Irix Cine 15mm T2.6 Canon EF (Imperial - Feet)

The Irix 45mm f/1.4 GFX is a professional lens designed for FujiFilm GFX cameras. It features a high quality construction based on the knowledge of Irix Lens engineers they have gained in the development and production of full-format lenses.
The lens is equipped with an aperture consisting of 9 rounded fins. It provides gentle background blur when blending and a circular bokeh. The lens construction also has an aperture ring that works smoothly.
With the focus lock function, you can fix the focus ring in a certain position. This is especially important for landscape photographs, but also if you want to maintain a certain distance from the motif (e.g. in the studio or on the road).
The lens also has seals in 5 places that protect the lens when working in difficult weather conditions. Thanks to the closed structure, the lens does not change its length, so there is no air movement when focusing.
