For the opportunity review of the legendary Canon EOS 7D body camera Many thanks to Georgy Abramashvili.
The Canon 7D is a very unusual semi-professional camera, although I personally consider the Canon 7D to be a true professional crop camera. The Canon 7D is the only camera in its subclass of Canon's DLC, the newer EOS 6D is already full-frame, and the EOS 50D and eos 60D lower level.
The Canon 7D uses an 18MP CMOS sensor. Now with a large number of megapixels you will not surprise anyone, especially after the release Nikon D800... For most amateur tasks, 18MP is quite a lot, but professionals can squeeze all their potential out of 18MP. The camera can form images 5184 by 3456 pixels (17.9MP). Cameras have the same matrix. Canon 600D, 650D, 550D и 60D. True, it is worth noting that in Canon 650D a slightly modified version of the matrix is used, which made it possible to double the maximum ISO value. You can take a look at my interesting article, which conducts an experiment on 'megapixel' - Battle of Megapixels.
Canon 7D attracts itself very high speed burst shooting. Shooting speed reaches 8 fps - This is an excellent indicator for a crop camera. No other crop camera with APS-C sensor from Canon can shoot at such high speed, only Canon APS-H and APS cameras can do it. Interestingly, Nikon has as many as 6 APS-C cameras that can reach this speed, but Nikon has a lot of limitations and nuances to achieve this burst speed.
However, in order to process such a large amount of data when shooting at 8 fps, the Canon 7D uses two DIGIC 4 processors. The weakness of the Canon 7D is a small frame bufferhowever, the new firmware slightly increases the number of frames during continuous shooting. Canon 7D outperforms even some of its full-frame brothers in performance - see the section for more details. the performance of all Canon.
Canon 7D is very well made, the camera body is made of magnesium alloy. The camera body has weather protection. In the hand, the Canon 7D sits very comfortably, it feels like a serious level device.
An additional monochrome display is simply an indispensable item for quickly adjusting basic camera parameters. The additional display has a backlight function. I really appreciate advanced cameras with an additional display, top-level cameras even have 2 such displays. The camera has a variety of controls that you can quickly get used to.
Canon 7D has a 3-inch display with 920 thousand dots. Now you won't surprise anyone with such a display, it is very convenient to view the footage, dig into the menu settings and shoot video.
Canon 7D can use ISO 100 to 6400 units and expand the value to 12.800. I can’t say that the camera has a low noise level at high ISOs, since now there are cameras that make noise an order of magnitude lower, especially considering the full-frame line of cameras. Minimum excerpt is 1 \ 8000, which is an excellent indicator.
The optical viewfinder deserves special attention - it has 100% frame coverage, which means that no extra details on the sides of the frame will get into the picture. For example, even on my full frame Nikon D700 the viewfinder does not cover 100% and you have to remember that after pressing the shutter button, extra details will appear at the edges of the picture.
Canon 7D uses 14-bit color depth, the camera supports 14-bit RAW (CR2). A deep color depth is very important in image processing. By the way, I updated the review Nikon D1X, with new software it can use 16-bit color depth.
Of course, the Canon 7D's very strong point is video. The camera can shoot Full HD 1920 × 1080 29.97 fps in MOV format, H.264 codec. Also, you can shoot 1280 × 720 and 640 × 480 at 60 or 50 frames per second. When shooting video, all basic parameters are available, the camera has a special button for starting / stopping video recording
Focusing is based on a 19-point sensor, with all 19 points being cruciform. The focus menu has several interesting settings, during the review I still did not understand the full possibility of the focus system working methods. The Canon 7D does not have an autofocus backlight.
Measurement exposure built on the basis of a 63-segment sensor, the sensor takes into account the focus, color and brightness of objects in the field of view of the camera. Many Canon EOS cameras use 63-segment metering exposure. You need to get used to the operation of an exnometer of any camera, just like the work of an automatic white balance.
Canon 7D camera has huge amount of useful features:
- Matrix dust cleaning system
- Great battery with over 1000 shots. The number of frames shot is highly dependent on many parameters.
- Automatic bracketing exposure и white balance
- Creative auto mode and image management system
- Automatic ISO first versions available from 100 to 3200 units
- The camera uses fast CF memory cards. True, the camera has only one slot for memory cards
- INFO key, with which you can set the basic camera settings, a very convenient thing
- Canon 7D can automatically correct vignetting with 'Peripheral Illumination Correction'
- Auto brightness correction, allows you to expand the dynamic range of the image
- Fine-tuning the focus, the camera remembers 20 lenses
- An optional battery pack can be attached to the camera
- and many, many others
The camera using the built-in flash may control external flashes remotely. Only 4 Canon cameras can do this: Canon EOS 600D, Canon EOS 650D, Canon EOS 60DCanon EOS 7D. By the way, with Nikon, as many as 12 models have such a function, however, Canon EOS 7D can control 3 groups of flashes, and Nikon's built-in flash can only control 2 groups. In this case, the Canon EOS 7D can use high speed sync with external flashes in this mode excerpt with flash not limited to threshold XSync in 1 \ 250 seconds and can even be set to 1 \ 8000. High-speed sync is a must have for flash photography during the day.
A direct competitor is often called Nikon D300s, I made a small tablet of the main parameters, the advantages are highlighted in green.

There is a modification of Canon EOS 7D, which is called Canon EOS 7DSV, which is aimed at the use by professional photographers in the studio, but I do not see any serious differences, except for the barcode scanner and a slightly different menu. Also, Canon EOS 7D of old releases can be updated using firmware version 2.03, the new firmware adds a couple of useful little things.
Personally, it seemed to me that the camera control system was not very convenient, most likely this is due to the fact that I was simply used to the Nikon system, which I use most often. In general, the Canon EOS 7D is just a fairy tale, especially for advanced amateurs who are trying to squeeze the maximum out of cameras. A simpler alternative is Canon 60D.
Prices for modern Canon cameras in popular stores can look at this link.
In comments Can I ask you a question on the topic and you will answer, and you can also express your opinion or describe your experience. For the selection of photographic equipment, I recommend large catalogs of various photographic equipment, such as E-Catalog, or large online stores such as Socket. Many little things for the photo can be found on AliExpress.
Canon EOS 7D is an excellent camera with tremendous burst shooting speed, unmatched in terms of speed among other crop cameras from Canon. The quality of video and photos is at a high level, the Canon EOS 7D has an excellent focusing system and an excellent protected body. You can write about advantages for a very long time, in a word - I recommend.
