Sony competes with Canon, Nikon and other camera manufacturers and thus, is not afraid to equip its entry level camera with a full bag of tricks. Canon competes with Canon and is so afraid that their lower priced full frame cameras such as the 6D Mark ii will compete with the 5D Mark iv that they "dumbed down" the 6D2. I keep finding things that I need and that the 6D2 doesn't provide. Simple things like a 1/8000 second shutter capability (the 1/160 maximum sync speed sucks also!). I have to use an ND filter if I want to shoot wide open at ISO 100 with my 85mm f/1.8 lens in bright Southern California sun. Sure I could use ISO 50 but, at that ISO, the 6D2 takes an additional hit in dynamic range. With the dynamic range already pretty bad, I don't want to do this...
Canon tries to excuse the limitations of the 6D2 by reminding people that it is an "ENTRY LEVEL" full frame DSLR. Guess what folks? The Sony A7iii is an "ENTRY LEVEL" camera also and look at the features it provides...
My solution to the problems of the 6D2 - sell it and buy a Sony A7iii with an adapter to use my present Canon glass.
