Additional information:
The compact KIPON 75mm Fuji G mount lenses are ideally suited for medium format cameras. They are small and fast enough to handle any and all photographic situations. For instance, cropping portraits, or landscape and street photography. All capabilities for image composition and visual imagery can be creatively realized with the manual lenses.
The puristic 75mm Fuji G mount lenses with a constant speed of 2.4 and focal length of 75mm come in black and are initially available for Fuji G mount systems. During development, particular attention was placed on achieving a light weight and compact size in order to live up to the guiding principle of medium format cameras.
The design calculated with demand for highest image quality for digital sensors is based on classic constructions. The photographer is in complete control when selecting the focus point and thus the original photography experience is preserved compared to autofocus lenses.
