Picked up a Canon 7D mark 2 today. As a fight photographer using a Canon 1Dx, I am very happy with the camera and the results.
I used the camera with a Canon 24-70mm f/2.8L II at a Muay Thai demo tonight.
Menu system, ergonomics, using the camera, and the results were very familiar. Felt like I was shooting with the 1Dx.
Since Adobe doesn't have an update for the Canon 7Dm2 yet, I shot Raw to CF and Jpeg to SD, which slowed down the buffer a bit. Not sure if this is the same problem as the 5Dm3 where the SD card slot shortens the buffer (if I remember correctly). I'm used to the 1Dx 32 RAW buffer so the difference was new to me.
Here's a Jpeg sample straight out of camera (added watermark). IMO, it's quite good for a jpeg.
The Canon 7Dm2 is definitely a good backup to my 1Dx. I can still comfortably shoot weddings and events with this no problem. I can see why Scott Kelby likes this camera so much.
