Sony a7RII Compares Well to Fujifilm GFX 50S and Pentax 645Z

Image Resource updated their Comparometer to include the Fujifilm GFX 50S so I took the time to put together the comparison above to see how these 4 similar megapixel cameras compare at 100 ISO and 12,800 ISO for Fujiaddict. At base ISO they are all very similar, but by 12,800 ISO the Sony a7RII pulls ahead. If you check out Image Resources Comparometer the Fujifilm GFX50S is the best by a hair at base ISO arguably followed by the Sony a7R and then the Pentax 645Z. The Canon 5DS R isn’t far behind, but it really depends on what part of the image you examine. Each camera has it’s own strength. You can do your own comparisons here.

    While I’d like to grab a GFX for a variety of reasons, to me the a7RII appears to be ahead. When I factor in the form factor, the feature set, and the price point of the a7RII, I wonder if I should refrain myself from going for the current GFX thing.

    • Mine will be here Wed. I am waiting for the Sony a7RIII to get an R camera. I only have a Sony a7II at the moment.

      My impression is that the GFX is over all better throughout most of the frame, but you also have to take into consideration the dynamic range and the way medium format changes the look of a photography.

        I shot with the GFX on Saturday and the dynamic range & detail is astounding! The only way I can describe it, is that “it’s as if you are standing there looking at the real scene”. I don’t get that with my a7R. Don’t get me wrong, the a7R is very good, but the GFX has a quality & look that hard to quantify. It also lends itself to enlargement very very well. I did a 75 inch print and it too looked like I could walk right into the scene.

          Yes, that is it. When I shoot first time with the Pentax 645Z, I had the same impression. But, 645 is bulky and uncomfortable to walk around.
          GFX Body is great. The lenses could be better, compare to the new Hasselblad X1D-lenses! Oh my goodness. I do hope Fuji, Hasselblad or other manufacturer will bring an adapter on the market.
          But, cross the finger…… Sony a9 will be middle format as GXF and X1D, but with BSI-sensor! Sony still wait to come out, because the lenses are not ready yet! A7rIII with more Megapixel! It not brings more to the a7rII.
