This lens features a unique optical system designed by master lens craftsman DJ, housed in a slim barrel. The lens is multi-coated for clear and sharp image rendering. The moderately wide 35mm field of view allows you to capture both the subject and its surroundings, making it ideal for street photography, landscapes, and everyday documentary.
Rangefinder coupling compatible. Minimum focusing distance: 0.5m
It supports a rangefinder coupling mechanism, allowing you to get as close as 0.5m to your subject for shooting*. The focusing knob allows for smooth focusing. Distance and depth-of-field scales are located on the front of the lens, making it useful for snapshot photography where you can set the shooting distance in advance while checking the range of focus. The aperture ring is stepless without clicks, allowing you to finely and continuously adjust the aperture value to suit your shooting intentions.
*Rangefinder coupling is not supported at shooting distances between 0.5m and 0.7m. Please use live view or similar to check the focus.
