Large bright viewfinder. I think it's very important for the job. With 100% coverage. A little less than on FF, according to the sensations. This is not the case on older models.
Assembled perfectly, Japanese assembly. A lot of magnesium, dust and moisture protection. Large comfortable grip. Ergonomics are top notch. I especially like the joystick, with which we can quickly change the focus points (or point).
Focus system - 19 points - all cruciform, cover most of the frame. Works precisely and lightning fast with the appropriate optics. Separately, I would like to note the tracking mode.
Battery - holds 1000+ shots. Plus is used on other Canon cameras, such as 6D and 5D for example.
As for the functionality - by and large there is nothing to complain about.
I didn’t list the obvious advantages such as 8 frames / s, but indeed they are only done in good lighting, but excuse me, why would you shoot something at night that would require high-speed shooting. It's hard to imagine.
Here, some wrote about the supposedly not large buffer when shooting in RAW, do not believe it. A long time ago, Canon released a firmware ate. Now the series shoots back without slowing down to 23 frames on average, which is very good even by modern standards. I can compare with 6D, which I also use, it shuts up after 10 and writes to the SD card for a long time (not even the slowest one). 7D works just fine when using a fast card.
As for me, even for the year 2022 remains very decent equipment for shooting action in all weather conditions, but with good lighting.
What’s more, the price is now very reasonable.
