Fujifilm Fujinon XF 90mm f/2 R LM WR review
Fujifilm Fujinon XF 90mm f/2 R LM WR – Autofocus
Inside the Fujinon 90mm f/2 is a newly developed focusing system. Called the Quad Linear Motor system, it is made up of four focus motors working together to shift the large focusing group inside the lens. This system aims to be quiet, accurate and quick, and Fujifilm claims focusing speeds of 0.14sec.
In use, the autofocus is very quiet and can only be heard very faintly when all other background noise is removed. Even when shooting at a quiet wedding ceremony, nobody would be any the wiser when the lens is focusing. I used the 90mm on the Fujifilm X-T1 with firmware versions 3.2 and 4.0. I shot a number of portraits using flashguns with the model lit solely by a tiny LED light for focusing. Both the speed with which the lens locked on and its accuracy were impressive. With firmware 4.0 the face detection certainly improved, as well as continuous focusing.
In comparison to the Fujinon XF 56mm f/1.2, the lens appears to focus a fraction quicker and, overall, it boasts better consistency and accuracy. While it’s not quite as fast as the Fujinon 16-55mm f/2.8, and can seem a little sluggish at times in comparison, it’s still reasonably quick and very accurate.
