French website Le Monde De La Photo (The World ofPhotography) has recently published test results for three Fujifilm lenses on a Fujifilm GFX 50S camera. They tested Fujinon GF 63mm f/2.8, Fujinon GF 120mm f/4 and Fujinon GF 32-64mm f/4. The lenses and the cameras will be released on February 28, 2017, so this is a good chance to take a look at the performance they offer.
According to the tests, all the lenses have performed very well in terms of performance, autofocus and ISO when attached to the GFX 50S camera. But the sharpness results were exceptional. This review is an early first look, but it gives a nice insight on the lenses and this mirrorless monster of a camera. Le Monde De La Photo has published the graphs showing the sharpness of these three lenses, and here are the results.
