Together with the 18mm and the 60mm, the Fujifilm XF 35mm f/1.4 R for the Fujifilm X-series is part of the very first line of System camera lenses by Fujifilm. What immediately stands out about this 35mm lens, is the use of an aperture ring with steps of 1/3 stops. This allows you to determine the light very precisely, and to increase or decrease your depth of field. Besides that, you have, when the camera supports this, full communication with the body. This gives you a super fast autofocus, and both an optical and an electric viewfinder.
