Photozone, one of the web's most-trusted resources for reviews dealing with interchangeable camera lenses, has just posted an in-depth review of the new Fuji 56mm f1.2 Fujinon lens, which is among the latest in Fuji's ever-expanding lineup of-mount lenses.
So, how does it do in practice? Short answer: very well.
Optically, the lens is really good. In terms of sharpness, the lens is good right from the get-go at f1.2, with the corners only slightly lagging behind the center. The lens does sharpen a little through f5.6, which is where the corners pull nearest even to the center. As for chromatic aberration and distortion, both are very well controlled and should not present any real problems. Vignetting? As is to be expected for a large aperture lens, vignetting is quite pronounced with nearly 2 stops corner darkening. Stopping down to f2 eliminates the problems in real life shooting.
Mechanically, the lens uses all-metal construction and AF is via a focus by way of a 'DC Coreless Motor,' which produces quiet, though by no means silent, AF. Focus is controlled by a focus-by-wire system, which means that there is no AF/MF switch as this function is controlled on the camera. As for speed, it will depend on the camera. In its review, Photozone used a X-T1, which incorporates Fuji's latest AF system. Speed on the X-T1? Fast, but not quite ultrasonic fast. In addition to the MF ring, there is an old-fashioned aperture ring on the rear barrel of the lens, too.
If there is any gripe at all, price could be the only concern as the lens retails for around $1,000 but by reading the above, at least you do get what you pay for.
Overall conclusion: praise at the highest level.
