【Product Contents】 ・C-mount lens 35mm F1.6 (BK) ・C-FX mount adapter (BK) The above two items are included. ※ Lens cap and rear cap are included. ※ For mirrorless cameras only. Not compatible with single-lens reflex cameras. This is an old lens that allows you to enjoy unique image rendering. It uses the "cinema lens" standard called C-mount, and is a manual lens used in surveillance cameras. It has the style of an old lens from a while back, where you manually turn the rings to adjust the focus and aperture. A feature of this lens is that old lens enthusiasts can easily enjoy impressive "swirly bokeh" photography. By converting the mount shape of the C-mount lens, it can be used as a single-focus lens for Fujifilm X-mount cameras. Fujifilm X-system mirrorless cameras include the X-Pro2, E1, E2, E3, A1, A2, A3, A5, M1, T1, T10, T20, and H1 models. It can be used with any X-mount camera. ※ I used it once after purchasing it. It was very good, but I am selling it due to a change in my camera body!
