I am currently doing a lot of bird photography (and small rodents - Squirrels chipmunks etc) but also do landscape and all around. I am not a pro just someone who loves taking pictures.
Unfortunately I am also someone who loves gear! Definitely have GAS - Gear Acquisition Syndrome.
Currently I am shooting with an 80D and 90D as well as a 6D mkII. I recently got a 5D Classic because it is just plain fun to use and I don't mind leaving it my car so I always have it.
My 90D does 10 FPS and I can get about 25-28 Raw+JPG in a burst but then it has to catch up. Two things make me look at the 1D is the supposed 20 FPS and the bigger buffer (unlimited for JPG)
10 FPS has been fine although 20 would be better, but the main thing is the bigger buffer, as I am typing this I am wondering if finding a used 1D mk I one that is sound but may be rough looking, does it or is it the mk II that has unlimited JPGs on the buffer?
I am selling some guns anyway to thin the herd and wouldn't mind putting it into camera gear
