TYPE OF TEST: CFR-2 (What does this mean?)

Canon 7D and Image Quality

Ok, let’s talk about Image Quality.

Many photographers have been evaluating the Canon 7D image quality. Most of the tests show satisfying and outstanding results. But not everybody’s happy. Why are we seeing so many different opinions about the same camera? One answer is that the test situations are different; file format, raw-files with no editing or finished files with editing. Lens quality is also extremely important.

Another fact is that no two photographers are exactly alike and there will always be some differences about what people think about image noise, sharpness, colors etc. The discussions and tests rarely focus on what can be achieved with these cameras. Is a picture perfect because it has no noise and is extremely sharp? Have we evaluated the composition, the passion, and the story the photographs are attempting to communicate to the viewer?

Image quality and file format

In my first beta test of the Canon 7D I was shooting with “raw + jpg”, because I could only judge the results from the jpg-files. After that I looked through thousands of raw files, and there were some differences in the files. This was not unexpected since the jpg files had already been through some kind of image editing (sharpening, contrast, saturation, color space etc.). It surprised me that the raw files had that much less sharpness than the jpg files (set to standard sharpening). Therefore, many of the raw files from the Canon 7D need more sharpening in post processing than the 5D mark II or 1DS Mark III. What’s the reason for this?

I have been told that the 7D has a stronger low pass filter in front of the image sensor; stronger than in other Canon cameras. This will reduce the image noise but it can also reduce sharpness. This is one of the reasons why full-frame sensors are usually better than 1.6 crop sensors. There is also more noise in the raw files from the 7D, than full frame cameras like 5D Mark II and 1DS Mark III. In my opinion the 7D is better than 50D for noise; some place between the 50D and the 5D Mark II and 1DS Mark III. It’s not difficult to increase the sharpness and reduce the image noise in post-processing afterward.

Image Quality and raw-file processing

I usually use Adobe Lightroom (LR) for importing and developing of raw files, and then converting them to 16 bit tiffs for the final tweaking in Adobe Photoshop CS4 (PS). In LR 2.5 it is possible to process raw files from the 7D, but the “camera calibration” could only be set to “Beta”. I also felt that the 7D raw files had more noise and less sharpness compared to using Canon’s own Digital Photo Professional (DPP). I develope most of the raw-files in this tests from 7D with DPP and then export them as 16 bit tiffs for editing in PS. This is a much slower workflow than my normal use of LR. The newer LR 2.6 is only slighter better than LR 2.5. Hopefully, the still not released LR 3.0 will give us even better processing of raw files from the 7D. It sometimes takes a few months before software is fine tuned for specific cameras.

Later in this blog under “Image Quality and sharpness” I have some example images developed in LR and DPP (sorry no Aperture).

Image quality in highlights

To be honest I´m quite impressed with the dynamic range in highlights from 7D raw files developed in DPP. Below are some images taken with 7D and 1DS Mark III, on a bright sunny day on the Falkland Islands in November. It may be difficult for most cameras to achieve the tonality in the highlights, but I think the 7D does a very good job!

Image quality and sharpness

I used the 7D as an action camera on the Antarctic Expedition in November and shot mainly with a 300/2.8 (85%) and the 70-200/2.8 (10%). Only 5% of the images were shot with a 16-35/2.8 and a 24-70/2.8. Due to heavy weight and a lot of extra HD video equipment, I didn´t take along my beloved 600/4.0 which I normally use for wildlife photography.

It’s difficult to write about sharpness because opinions may differ from person to person. If I upload an image which I don´t think is sharp enough, there will be some that disagree with me. Some of you will also disagree about pictures I think are sharp. It might be best to show you some images taken with 3 different cameras. You can then decide for yourselves.

Which camera do you think gets the sharpest pictures? It may have been difficult for most of you to guess if I didn’t tell you.

Image quality and colors

For me it is also important that the raw files have great tonality to the colors. In the pictures below I have some examples of birds photographed in bright sunlight and yellow backgrounds, which can be difficult situations to shoot.

Image and Highlight Tone Priority

Here are some images I took in Antarctica that I was not 100% satisfied with. These shots show increased noise and lack of sharpness in shadow areas bordered with bright backgrounds. In such situations I usually activate “Highlight Tone Priority” (CF.II – 3). I love to use this function in situations with difficult highlights, but when you give priority to the highlights you will compromise the quality of the shadow areas. This is especially prominent in picture #3 below which is developed in LR 2.6. After this experience I will only use Highlight Tone priority in situations where there are no important details in the shadows. So my advice is, be careful about activating Highlight Tone Priority on your Canon 7D camera.

Conclusion and recommendations

Ok, so what more can I say about the image quality of the 7D?

First of all the Canon 7D is a great camera, especially suited for action photography when fast AF-tracking is needed. The sharpness is very close to my 5D Mark II and 1DS Mark III full frames cameras. Sometimes I don´t think I can see any difference at all, but under some lighting conditions, like low contrast light, I prefer the 5D Mark II and 1DS Mark III.

Regarding the noise issues, I see more noise in the pictures from the 7D 1.6 crop factor, than my 2 full-frame cameras. This is especially noticeable in the backgrounds. This is not surprising. Maybe I should have tested the 7D against other 1.6 crop factor cameras…

The image quality is highly dependent of what kind of lenses you use. If you use high quality glass you will also get high quality images. Too many people forget about this.

LR 2.5 and LR 2.6 are in my opinion not yet optimized for developing and editing raw files from 7D. I hope Adobe will soon release Lightroom version 3 with optimized code for 7D files, to compete with DPP. I really love Lightroom, but I am not impressed how LR deals with my 7D raw files. For best image quality from your 7D raw files you should use the Canon DPP software.

Some photographers are not satisfied with the details in the highlights, but I think the 7D performs very well here. I can´t see any big differences at all when I compare the 7D against the 1DS Mark III. NB: I have only done outdoor field tests, so maybe with a “lab” test we may see some differences.

I think some images form the 7D need more sharpening in final edits than images from my full frame cameras. It also seems that the raw files from 7D don´t survive hard editing (adjustments in Levels, Curves etc.) as well as the 1DS Mark III and 5D Mark II files. The raw files from full frame cameras appear to have more dynamic range – not really surprising!

Canon 7D files are much larger than files from 1D Mark III / Mark IV. This is a big advantage when I’m outputting to a large format printer.

Be careful when using “Highlight Tone Priority” since it can sometimes reduce quality in the shadows!

And finally, the Canon 7D is a most excellent camera, better than I had expected from 1.6 crop-factor cameras. The image quality is not as good as the 5D Mark II and 1DS Mark III, but it’s close. In many situations it is very difficult to see any difference! I can highly recommend this camera, and I will use it on expeditions and assignments until maybe upgrading it for a Canon 1D Mark IV. If you already own a Canon 7D, I encourage you to enjoy it and don´t pay too much attention to photographers who aren’t satisfied with it. The most important thing is that you are satisfied.

TYPE OF TEST: CFR-2 (What does this mean?)

Canon 7D and autofocus

Many photographers have described the Canon 7D as an action camera. In November 2009 I had the opportunity to really test the AF system on a 3 week expedition to Antarctica. In this blog post I will share some of my experiences with the camera.

Autofocus on fast moving subjects

One important aspect of AF systems is their ability to follow fast moving subjects. Most AF systems fail when things get fast. Another problem with AF systems is the frequency of out of focus shots while shooting fast bursts, which can be very frustrating. So, how does the Canon 7D perform?

In the open sea between South-Georgia and Antarctica I was lucky enough to photograph the Antarctic Petrel. This bird is a fast glider in heavy winds and I have never before on my 3 other expeditions to Antarctica obtained good pictures of this bird in flight. When the bird showed up, I first tried to photograph it with my beloved Canon 1DS Mark III with 300/2.8L IS. This was not easy, so I switched over to my 7d and 70-200/2.8L IS. With 1,6 crop-factor and 200 mm this is almost equal to a full frame with a 300 mm. With its fast AF system the Canon 7D was better at locking on to birds in flight, and I got hundreds of sharp images.

I was also impressed with the tracking ability of the 7D. It could take many sharp pictures in fast bursts. Sometimes the AF lost track of the bird, but it was usually quick to get back on track again. Below are some pictures from a series on the Antarctic Petrel.

Autofocus with bright background

One of the situations were AF-systems usually fail is with bright backgrounds. The AF is usually lock on the background under these conditions. This was going to be a challenging situation for the 7D!

When shooting the Antarctic Petrel (and also the Southern Fulmar) I was shooting at bright sea water, and as you can see the results below are very good. I was very satisfied, because under these conditions getting sharp pictures is usually hard work.

One of the best things about getting sharp pictures is that you can go further and “play” with panning birds (or other subjects). For me a sharp picture is not the end of the story, but its a great opportunity to try different techniques with my camera. The picture below was taken with shutter speed at 1/15 of a second.

You can also get a feeling for the Canon 7D tracking abilities from the video below. This video was first posted 22 Dec. 2009.

Autofocus and sharpness

I will write about autofocus and sharpness in the next Canon 7D field review about Image Quality (#4).

Autofocus and settings

The AF settings in the Menu for the Canon 7D is closer to the pro Mark III and Mark IV cameras than the Canon 5D Mark II or 50D. The 7D has the ability to adjust the AF in many different ways. I may come back to these issues later in a tutorial etc. because these settings are not the same for all types of photography. The actual situation is very important for tuning your 7D to perform 100%.

The most important thing about AF-settings is the “One Shot” or “AI Servo” setting. I always use “One Shot” for non-moving subjects, and “AI Servo” for moving subjects. The 7D, 50D and lower also have a “AI Focus” setting which is something in between. To be honest, I don´t like the “AI Focus” setting at all because it seems to slow down the tracking ability of the AF system. When shooting the running dog in snow I did some of the shots with “AI Focus” by accident. Big gloves with cameras may cause problems too. When I looked at the pictures later, it seemed that there were more unsharp pictures in the series taken with “AI Focus” than with “AI Servo”. So, I will recommend that you use “AI Servo” on moving subjects and forget the “AI Focus” option.

Another issue is frame rate. For 8 frames per second you have to adjust the camera. The odd thing is that the 7D uses same symbol as the Canon 5D Mark II does for slow sync. This might be confusing when using 7D together with other cameras.

The AF Modes are very intuitive and easy to use. By pressing the “Q” button on the back of the camera it is easy to choose the desired AF Mode with the FEL button. I mostly used the selective AF with 4 extended focus points. Also the spot AF is great especially with non-moving subjects. Without the battery grip I get tired very fast when doing action shots.

Conclusion

In using the Canon 7D I have been more than satisfied with action shots. I can track the subject with a high degree of speed and precision, which I really like. The Canon 7D has the fastest AF I have used on assignments and expeditions, and it will be interesting to see how the Canon 1D Mark IV performs compared to the 7D.

The AF-system on the 7D is very close to the pro cameras with settings to tune the AF to your liking. It’s much easier to change to the desired AF Mode with this camera. Why should this be more complicated than on pro cameras?

I don´t like the “AI Focus” option, but maybe some of you use it and is satisfied with it.

One thing that I have mentioned in an earlier blog is the use of the battery grip, especially if you have activated the AF-ON button under the thumb area (the middle button on the back). Without the Battery Grip I get tired very fast when doing action shots, and I will strongly recommend you to get this accessory if you want to shoot action.

UPDATE (22 Dec.): I’ve done a new test with the Canon 7D today. A new video and information about the frame rate is now available.

Canon 7D in cold weather. Video filmed on Canon 5D Mark II. NB: View it in full screen mode!!

TYPE OF TEST: CFR-2 (What does this mean?)

I´ve had many questions regarding the Canon 7D’s operation in cold temperatures. Last Friday was the perfect opportunity to test the camera for 3 hours in -23 °C temperatures. I dressed warmly and prior to testing I put the 7D and its batteries out in the cold for about 1 hour. This isn’t the smartest thing to do as I always recommend removing the batteries and keeping them warm when the camera is not in use. For this test I wanted to cool down the camera and batteries.

I have some favorite shooting places close to my office and I took along my dog “Chilli”. I wanted to test how well the 7D AF-system works in the cold. My question: Is the 7D a great action camera when the weather is really cold?

AF tracking

As you can see from the images in the above video, the 7D AF follows the running dog very precisely. The situation of a light dog, surrounded by white snow and the sun as back lighting, is a challenging situation for the AF. I think the camera did a great job following the dog. A few times the AF lost track of the dog, but it was fast getting focus back and following the target dog as it approached me. The camera´s fast tracking ability was not hampered by the cold temperatures. I also tried the Canon 1DS Mark III with the same setup, and it was not faster than the 7D (1.6 crop factor) even if it is a full frame camera. The situation in sub-zero temperatures and difficult tracking situations impressed me.

Frame rate

The Canon 7D shoots very fast in cold weather. During this test I was shooting up to 8 fps for a total of 32 images in 5 second. This is very effective when shooting fast moving subjects.

It’s very important to use the correct settings to use the high frame rates. First of all you have to select drive mode “high”, not low or single. This can be confusing since the Canon 5D Mark II has a symbol for high frame rate, that is the same as the low frame rate symbol on the Canon 7D. The symbol for the low frame rate in 1D / 1DS Mark III is marked with «L» which makes it very clear. When I´m out in the field I usually use all the 1DS Mark III, 5D Mark II and 7D, and in the heat of the moment it can be very confusing with different symbols for drive modes on each camera. This was the case during my first field test in the cold, when I didn’t get 8 fps, because it was set to low drive mode.

Secondly, you must deactivate noise reduction on high ISO. Even with a setting of ISO 400 you can only shoot 8 frames before the buffer needs a break.

Conclusion

The Canon 7D has absolutely no problems in cold conditions and works as expected. The batteries are really very good, and you can shoot for hours in cold winter weather without recharging the batteries.

PS: In my next blog postings I will test the 7D AF and Image Quality

Canon 7D in a snow blizzard on South Georgia Island, November 11.

TYPE OF TEST: CFR-2 (What does this mean?)

One issue I´ve been very interested in regarding the new 7D, is how well it performs under tough weather conditions. Some of my assignments and expeditions take me to extreme parts of the world, where cold temperatures, snow, rain, sand, or a mix of fine sand, rain and a splash of sea water are the norm. On my recent expediton to Antarctica I had a great opportunity to really test how well sealed and rugged this camera actually is. The other two cameras in my camera bag were the Canon 5D Mark II and 1DS Mark III.

This trip was almost the same 3.5 week photo expedition to Antartctica as last year, where I had a 50D and Canon HF10 HD video camera for testing. On that trip I destroyed the video camera on my first day at South Georgia, and the 50D camera had a one day “hangover” after a wet landing. After a few days I put the 50D away because it was not suited to those conditions. 3-4 photographers with Canon 30Ds and 40Ds broke their cameras during last year’s expedition. NB: My workhorse, the 1DS Mark III worked flawlessly, even after 2 “baths” in cold sea water. After these experiences, I wasn’t sure if the 7D and 5D Mark II would survive for the duration of the expedition this year.

Weather resistant

When I´m shooting I’m very focused on my subject and technique. The cameras and equipment experience extremely hard use. When shooting wildlife I´m usually laying on my stomach, with the camera in direct ground contact. This works great with most cameras if the ground is dry, but in Antarctica the ground is almost always wet, muddy or covered with snow or sand. On my recent expedition it snowed almost every day, and at times wet snow, which is worse than rain.

Rough weather conditions = rough images. This Antarctic Fur Seal was photographed with 7D and 300/2.8L on South Georgia.

I always use the 7D with the attached battery grip because it gives me a much better grasp of the camera. Some 5D Mark II users who use the battery grip have reported some problems with water leaking between the camera and battery grip. The battery grip for 7D is new and seems tighter and better sealed. In my case the 7D had absolutely NO problems with snow, rain and water (sea spray). This was just as I had hoped. I’ve also used the 7D on rainy days in Norway, without any problems. The 7D easily passed the rain and wet conditions test.

My 7D in heavy rain.

Wet snow in South Georgia. These conditions might destroy cheaper cameras after a few hours. I used a ThinkTank “raincoat” for my 300mm, but nothing over the camera.

So, what about the two other cameras?
My 1DS Mark III is built like a tank and is heavily weather sealed. I didn´t drop it into sea water this year, but used it without worry or protecting it from bad weather. It worked as expected, without problems.

The big surprise was the 5D Mark II. I used this camera as hard as (but not as much) the 7D and it performed superbly. I didn´t use any protection from rain or snow. The camera was used without the battery grip, which might have helped. The 5D Mark II has been on 2 expeditions to Svalbard (Arctic – 80° North) and one recent expedition to Antarctica without problems, so the weather sealing is robust enough for most conditions.


Conclusion
All three cameras performed very well  for the whole Antarctica expedition. The 7D performed as I had hoped, surpassing 10,000 exposures without a problem. I must admit that the 5D Mark II surprised me as well with its build quality. The 1DS Mark III camera is the most rugged and best weather sealed, but the 7D and 5D Mark II (without battery grip) performed 100% in my opinion.

I have not tried to drop the 7D or 5D Mark II “by accident” into salt water, but I don´t expect them to survive as well as the Mark III / IV cameras. It will be interesting to hear your opinions regarding your use of these cameras (especially the 7D) in extreme weather. Have you had any different experiences, or mostly the same as mine?

UPDATE (23 Oct.): I have now got the battery grip for the 7D, and this is a MUST!! Much better grip, and I’m looking forward to test it in Antarctica.

UPDATE (15 Oct.): I will take the Canon 7D with me to Antarctica in November and test it under rough conditions regarding water/weather, autofocus and image quality.

UPDATE (1 Oct.): I just received the Canon 7D (not Beta) and will spend the weekend doing more field tests. I have also got the new 100mm IS macro lens for testing, so give me some days and I will be back with some new fresh reviews…

UPDATE (24 Sept): I will get my 7D in the end of next week…

UPDATE (21 Sept): We have just opened this site for Canon Field Reviews. More tests will follow!!

UPDATE (16 Sept): 7D raw-files developed from Adobe Lightroom 2.5

It is now possible to develop raw-files from Canon 7D with Adobe Lightroom 2.5. In the pictures below I have only adjusted the White Balance and Curves slightly (no sharpening or noise reduction). The first picture is without cropping, and the second picture is cropped to show 100% view.

The picture is shot with a beta 7D camera (ISO1600) and the image quality may not be optimized, but I think this looks very promising at high ISO!

UPDATE (14 sept.): Video clips with 7D

Video Feature

One new feature on the 7D camera is a separate switch for video or still images, with a button in the middle of recording video. This is better than the select button on the 5D Mark II.

As with the 5D Mark II (with latest firmware), you have options for manual adjustment of ISO and aperture. This is very usepful!

A big advantage with the 7D is that you can shoot in 24P and 25P, not only in 30P. This is very useful for European photographers. It is also possible to capture in 50P and 60P, which gives you cool effects when playing the movie in slow motion (see the movie clip below captured in 50P). In 50P or 60P mode you can only shot in max. 720P (1280 x 720).

During my filming I didn´t get any overheat warning, which may occur with the 5D Mark II. Maybe I was just lucky, or the manufactor has done a better job…

I had unfortunately not with an external microphone, so I can´t tell anything about improved recording capabilities.

The AF-system in Live View Mode is still not as goos as I want to, so for my filming with long telephoto lenses (300mm and 600mm) I had to focus manually. However, both the 5D Mark II and 7D AF functions for face recognition, but that don´t work with birds etc.

….and the image quality in Video mode is just great!
FIELD REVIEW (10 sept.): Canon 7D (Beta)

Yesterday (10 Sept.), I got the opportunity to test the new Canon 7D camera for 4 hours. The light conditions were not the best, with bright sunlight and harsh contrasts, but testing is testing and fortunately I found some places with shade.

About the Test

This camera test is primarily a field test, where I did not try the camera in all possible settings for ISO etc. I have rather taken the 7D camera and photographed with it as if it were one of my 1DS Mark III or 5D Mark II cameras that I use daily. I have also refrained from thinking too much about it’s 1.6 crop factor, 18 Megapixels etc. and just fired away with it.

The test was conducted with a beta camera, which means that I have not had the opportunity to check the raw files, as I usually do. I have photographed in JPEG format (RAW + JPEG), and set the white balance to 5600K, AdobeRGB color space and “Standard” in the Picture Style. With beta-cameras there might also be features, settings and characteristics of the image quality that is not fully optimized. This must therefore be taken as a preliminary field test until the completed cameras will be released in the market.

Camera Design and Settings

Canon 7D is designed in the same way as the good old analog Canon 1N camera, and should therefore survive in wet conditions. During the 4 hours I tested the camera, there was no sign of rain. I will, therefore, come back with an update on this issue after my photo expedition to South Georgia and Antarctica in November, where the camera should be exposed to rain and salt water…

The feeling of holding the Canon 7D  was in my opinion better than the 5D Mark II but not as good as the 1D/1DS-cameras. The beta camera I tested had no battery grip, so my little finger did not get any rest or grip. This meant that I became a bit more tired when using my thumb on the AF button behind. I´m looking forward to try the camera again with a battery pack, so it will feel more similar to 1D/1DS Mark III.

The introduction of a separate button for recording HD-video force the multi-controller to be places slightly lower than on other cameras. In action shots I sometimes pushed the video button instead of the muti-controller when I wanted to change the AF point. Obviously, this is something you will get used to, but I think it will be better when using the battery grip.

As you can see in the video below, I fumbled a little to find the new button for AF modes, to the left of the release button. In the video below (in Norwegian), I instantly go through some of the most important camera functions with the 7D. Make sure you watch the video in HD and full-screen!

Autofocus

I’m shooting a lot of action pictures of birds, animals, people and other objects in motion, and in the 4-5 last year I´ve been testing all of Canon’s DSLR cameras, especially with regard to autofocus (and image quality). One of the things that are challenging for any AF system is to set the focus quickly and accurately, and not get confused by high contrast backgrounds, light or dark surfaces or other “distracting” elements.

During my 4 hour test period I didn´t get the opportunity to test the AF as much as I wanted, but I have some examples.

The options for how you want to configure the AF system is in my opinion much better and easier than on any other camera I’ve used. It´s far more intuitive how to choose between different AF options, and configure custom button functions on the camera should have. This is something many with me will appreciate.

I used the “Extended AF point” setting most of the time, which I think worked really well. In several situations, I quickly put the focus in the eye of a bird and the focus was not distracted by other objects nearby. In the picture example below, you can see a Canada Goose that beats its wings. My experience from other DSLR cameras is that the focus often “jump” to the front wing when it comes near the selected focus – in this case, the eye of a goose. With the 7D, the focus seems more stable and are not so easily distracted and stressed.

I also tested the AF system with subjects where I wanted to keep the focus point in the shadow areas. It is usually difficult to focus accurately when the objects are very dark or bright, especially when objects are moving fast. For example, with the duck below, the camera was able to focus on the duck´s eye, although it is very dark. This is a situation where the AF system of many cameras would rather set focus on the light water droplets.

I also tested the AF-system when shooting a fast moving radio controlled car (gasoline powered). It was pretty hard to follow this car with my 300mm, but the autofocus did a great job. I got many crystal sharp pictures, in situations where the car was heading straight toward me or across in front of me.

As a summary I would say that the new AF-system in the 7D is very impressing, and I will rate it as the best AF system I have tried (including 1D/1DS Mark III). In my opinion it is fortunate that Canon again has developed a AF-system with the highest quality AF point in the middle, rather than 19 AF points that sometimes fight against each other.

Sharpness

As described above, I´m impressed by the new AF system, and the sharpness is also very good. If you are keen to take sharp pictures, the you should consider the 7D.

None of the images shown on this page is sharped (or noise reduced) in Photoshop or other applications! The bottom image of the Greylag Goose shows a cropped view of the image displayed at 100% resolution.

Frame Rate

With 8 frames-per-second, the Canon 7D is one of the fastest cameras on the planet.

During my test I photographed both with RAW + JPEG which decreased the number of pictures before the buffer was full, but the frame rate was 8 frames / second. To illustrate this I took some pictures of water droplets that hit a pond. With limited time and disturbing wind, it was not easy to predict where the drops would hit the surface (especially with my 300mm). The three pictures below shows a sequence of approx. 0.4 second, where one droplet hit the surface during 3 exposures.

Image Quality

The most important priority for me is the image quality the camera can deliver. Even if the technical specifications are outstanding, it won´t help if the image quality is not good. Therefore, I have been very excited about the image quality of the new 7D camera, especially considering that it has APS-C image sensor (1.6 crop factor).

I shall be very careful to say much about the image quality, just based on the JPEG images I have taken with 8 bit color depth. But what I´ve seen so far, it can withstand comparisons with image files from both the 5D Mark II and 1DS Mark III, especially with ISO settings below ISO 800. I photographed most of my test pictures with ISO values at ISO 500, but with the water droplets, I used ISO 1600. Even at ISO 1600, I think there are surprisingly little noise, even without any noise reduction. I’ve always been very sceptical with 1.6 crop factor cameras, but I think many with me will be more positive about the APS-C format after the 7D camera.

Image files from the 7D’s 18 Megapixel sensor resulted in RAW files of around 22-23 MB, which is about the same as for both the 5D Mark II and 1DS Mark III with approximately 21 megapixels. This was somewhat surprising, but perhaps the reason for this lies in the firmware in the beta-camera. The size of the pictures I got were 5184 x 3456 pixels, which really beat the 1D Mark III (3888 x 2592 pixels). With Canon 7D you can make great 23” (A1) prints from slightly cropped images!

Summary

Canon 7D combine very good image quality with a fast and accurate AF-system. I think this will be a popular camera for shooting action. The camera is in many ways closer to the 1D Mark III camera, rather than the 5D Mark II, and a good step over the Canon 50D. I think many photo enthusiasts and pros will acquire the 7D camera. In my case, this will be the first 1.6 crop factor camera, I will bring in my photo bag on assignments and expeditions.

The picture quality from the 7D pleased and surprised me, and both amateurs and pros can now get a decent action-camera for a reasonable price. I have no doubts about replacing the 1D Mark III with 7D (with battery grip), at least if it is as weather-resistant and sturdy as announced.

If you have questions or comments about the 7D camera, you can use the comment field below. I will also provide updates when I´ve tested the raw files.

Thanks to Einar Breen for filming and helping me on the test day!
