So I do a lot of photography for my job- mostly boils down to high quality product photography. I used my friend’s a7 a couple times over the last year and was really shocked at how high quality the pictures were. I was thinking of buying one, but there are so many different models with slight differences... which is the most worthwhile to purchase? I see A7, a6300, and a6000 are all available for around or under 1000. A6000 is definitely the cheapest... Any thoughts here on the advantages? Is it better to get the newer 6300 than the a7?
