Where I feel the R7 will benefit me are on a few accounts:
- Replace my M50 (longer battery life, dual cards)
- Better AF than my M50 (like real working eye AF instead of the first gen version)
- Nicer ergos I feel (other than dial issues, lack of some buttons)
- 15fps mechanical interests me over the 10 I get now, but probably will hardly ever use 30fps ES.
Not sure what to think about the lack of a grip though, or that strange dial/joystick (but they are related, placement assumes no grip will ever work with the camera).
So even if this isn't a 7D3, I would just continue to use my 5D4 and R6 for that type of work where I would have used the 7D2 (and it helps I sold the 7D2 some time back for the M50), the R7 would come out for wildlife/hobbyist work as needed with details/resolution I cannot get today (24Mpx vs 32Mpx).
I wish more people had gotten time with the camera and posted videos, etc. I guess more will show up over the next few weeks like they did with the R5/6.
