Ive got an interesting story as to why im possibly very interested in the high mp canon eos r camera.
over the past two years i felt a bit let down by canon for not supporting the "low budged" wildlife community as much as wished for. I had really hoped for the 7d iii and when the rumors about no 7d iii and only a 90d showed up i was very disappointed.
Then i saw sony announcing and releasing the 200-600 and the a7r iv, which seemed to me like everything i had whished for in a portable wildlife setup, so i bought the camera.
But for the last two months i only had problems with the sony setup. my plan was to use my sigma 150-600 sport with canon mount on a sigma mc11 adapter until i could save enough money to buy the sony 200-600. With the adapted lens i had a big backfocus at 600mm and couldnt really use it. So i speed up my saving and quickly bough the 200-600 but i had the same backfocus on that too, so i sent it back.
I then tested my sony a7r iv with a completly different 200-600 at my dealer and again the backfocus. My dealer then exchanged it against a new a7r iv... but still the same backfocus.
I even sent in bouth of my sony a7r iv for repair but they said they cant do anything about it (only sent in the body, not the lens).
Now im visiting my dad and checked out the camera store near his city and tried out their a7r iv and 200-600 they had... again a backfocus.
I dont know why noone so far has talked about this problem. Maybe they dont pixelpeep enough.
Well ... at this point it seems to me like sony is really a huge let down for me.
So i look forward to that canon, but im afraid it probably wont focus well enough for wildlife, what do you guys think?
