This is NOT about how you use your gear, I don’t judge how you shoot. will keep it as objective as I can.
Sony colour science between the A7 and A72 are widely considered to be “off”. This isn’t my opinion, this is the opinion of the general community.
Fuji colour science, even from the X-T1 are widely considered to be good, and better than the Sony of that era.
Sony Auto focus in the A7 and A72 are widely considered to be below par of that era.
Fuji auto focus from the X-T1 are considered to be great at the time, and still perfectly acceptable even now.
So it is perfectly logical for someone to suggest NOT getting the Sony A7 for those 2 reasons alone.
The argument is “go manual”. Sure you can do that, but you only have by-passed 1 of the 2 points above, it’s colour science is still below par, accordingly to the community.
And to suggest going manual lenses, then you would go into it wholly knowing the 2 downsides above, then you really have to love manual focusing that much to really sacrifice everything else. That is a niche, wouldn’t you say?
And let me be more clear now, I feel like I am repeating myself here a lot. I am sure you can get good images from it, but so can the Fuji or really most modern cameras, what we are talking here is the original files produced, the colours that comes out of the camera. Because we are talking about the camera, we are not talking about the skill of the photographer after you put it into the computer.
Sony A7/A72 would not get my recommendation given what
@wibbly has already to hand.
p.s. at no point here have I talked about what lenses I have. At no point here have I talked about what lenses he should buy or any specific lenses at all. I don’t think I ever have suggested to anyone to buy any AF lenses.
The subject here is purely the A7 and its AF and files.
