GFX50R, SONY A7CR & GFX100S (50 vs 61 vs 100)
5

I picked up and Sony A7CR with a couple of lenses (50mm 1.4 GM + Sigma 90mm f2.8) last week as I wanted something small again with fast auto focus, without giving up much in image quality.

I was stuck at home for a few days so I took some casual comparisons photos. Bear in mind that I'm no pro and these were really just taken to help me decide what to sell. But I thought I would share them just case it's useful to anyone. Excuse the dodgy model used, I was all that was available!

Coffee cups (pictures with A7RC + 50mm 1.4, 50R + 80mm & 100S + 80mm)

To me the A7RC + 50mm looks soft at 1.4 (or I messed up focus), but get's much better after. Still, to me you need to get closer to f4 to match what the Fuji's are doing wide open).

By f8 they're closer still. I still find both Fuji's sharper in the details of the cups, but possibly prefer the A7RC over the 50R.

Either way this seems to me like the lens is the biggest difference here.

Bad model (with A7RC + Sigma 90mm 2.8 & 100S + 110mm), Using the Sony app and fuji 10 sec timer.)

The light changed for the 110mm shots a little which washed out some of the colour and I had to lift the shadows more. But I don't think you can beat the 110mm. Plus (no picture here) the fact it is still so sharp even wide open helps.

But... the sigma is a £500 tiny lens on a tiny camera.... I love them both.
