Introduction

Typical for most Fujinon lenses, the build quality is very good thanks to a tightly assembled metal body based on a metal mount. The focus ring operates very smoothly. Interestingly the lens does not provide the focus clutch mechanism that we have seen in the Fujinon XF 14mm f/2.8 R and XF 23mm f/1.4 R. Fuji's strategy is a little unclear in this respect. The lens has also a dedicated aperture ring with distinctive 1/3EV steps. You may notice that the aperture ring shows white and red-colored numbers. The red numbers indicate the T-value (transmission value) and at large-aperture settings they are a little slower because of the APD filer. A barrel-shaped lens hood made of plastic is part of the package.

Ages ago Minolta (now Sony) introduced the 135mm f/2.8 STF ... the only other mainstream lens featuring an apodization filter out there (as of the time of this review). Because of the filter, the lens didn't provide auto-focusing. Well, that was at a time when the dinosaurs (DSLRs) still ruled the world but the situation is a bit different with mirrorless cameras now. The effect of apodization filter is poison for phase-detection AF systems but in the mirrorless world, contrast-detection AF is naturally available thus the Fujinon XF 56mm f/1.2 R APD can fully take advantage of this. While there's a slight penalty in certain situations, the AF speed remains certainly fast enough (without being really fast though). The AF noise level is low albeit noticeable. Manual focusing works "by wire" thus by triggering the AF motor - this works fairly well although the ultra-large aperture makes things more delicate compared to slower lenses.
