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.
The graphs show lens sharpness of the three lenses, divided into six categories ranging from “Superlative” to “Low”. The sharpness was measured at different apertures, and different focal lengths for the 32-64mm lens. And as you can see, all lenses show superlative performance at f/8 and f11. The 32-64mm lens shows the worst result at f/4 with the focal length of 46mm. However, it has a truly stellar performance at 64mm.
If you are interested in the camera performance, here is a short excerpt, roughly translated from French:
LENS PERFORMANCE: The dive was calculated on the basis of standard style Jpeg, as Raw conversion software was not yet available. Overall the sharpness is always of high level, from very good to superlative according to the focal length and the openings. Only the corner area is sharply recessed at the focal length of 46 mm on the zoom, in all cases the dive is superlative over the field at medium apertures. The vignetting is never annoying and the chromatic aberration almost invisible, the only small defect noted is a cushion distortion (-0.15%) a little strong on the 120 mm macro that can be used to make reproductions of Works of art or documents, a little post-processing will be required.
AUTOFOCUS: the contrast detection autofocus is very precise but not always ultra-reactive, and the continuous shooting at 3 frames second is not really targeted sport but sufficient to capture changes of attitude of a model.
ISO: On our “Nessie” basic test with a maximum sensitivity of 12,800 ISO, there is little degradation of the structure of the image, with the rise of a very light grain observable at 100% screen but quasi- Invisible on a glossy A1 paper print. The contours will nevertheless be a little less sharp than at 6 400 ISO, a grade that does not present more granulation than an average film format 100 ISO.
