This is the second in a series of posts on the Fujifilm GFX-50S. The series starts here.
Normally the first thing I do when I review a camera is evaluate the sensor, but the bulk of the GFX sensor has been around for quite some time, being used by Phase One, Hasselblad (twice), and Pentax. There may be some surprises, but they are not likely to be earth-shattering. So the first thing I’m gonna do here is look at adapting full frame lenses to the GFX. Probably because of my long history using V-series Hasselblads, I love square pictures. One of the things that is attractive to me about the 33x44mm sensor in the GFX is that it’s got about 38 megapixels when cropped to a square, and the image circle for such a crop is not much larger than that of the 24x36mm full frame circle. 46.67 mm for the square GFX crop, and 43.27 mm for the full frame camera.
I did a series of quick and dirty tests of one native lens, the 63, and a lot of adapted ones on the GFX. These tests were just intended to weed out the obvious winners and equally-obvious losers, so I will know what lenses deserve more refined, and more time-consuming, tests.
I am now removing these tests, since I have done better ones.
Here’s the visual test for the Zeiss 135 mm f/2 Apo-Sonnar DF.2:
Here’s an Otus 85 mm f/1.4 test:
The 135 mm f/2 DC-Nikkor covers about as well as the Apo-Sonnar, but is not quite as sharp.
