IRIX 45mm f/1.4 Dragonfly Lens for Fuji GFX

The Irix 45mm f / 1.4 GFX is a professional lens designed for FujiFilm GFX cameras. It has a high-quality construction, based on the knowledge of Irix Lens engineers gained during the design and production of full-frame lenses. The equivalent focal length of 45mm for the FujiFilm GFX sensor is ~ 36mm, which combined with the very high resolution of the lens, makes it possible to capture every subject of photography. The combination of fast aperture and length makes this lens extremely practical. You can use it both for photos on which you can blur the background special effectively.

Optical technologies applied in the construction of the Irix 45mm f / 1.4 GFX lens ensure an extremely good speed result - f / 1.4. This parameter provides exceptional light transmittance, perfect for work in low light conditions, creates a unique depth of field and enables you to capture the picturesque separation of the object from the background. The Irix 45mm f/1.4 lens was designed to give a detailed image from just f/1.4, being even sharper at higher f-stop values.

High-quality lenses must be ready to work in all conditions. Therefore, the design of the Irix 45mm f/1.4 GFX has no compromises - our premium class lens uses only the best materials in its construction. The guarantee of operation in all conditions is provided by a sealing system located in key areas of the lens. Equally important, the lens does not change its dimensions during focus pulling, eliminating the risk of dirt particles getting swept into the internal structure. These properties not only allow you to work in demanding conditions, but also guarantee the cleanliness of the camera’s mirror chamber sensor.

The Irix 45mm f/1.4 GFX has dedicated stepless aperture ring that ensures smooth and quiet operation. The lens is equipped with an aperture consisting of 9 rounded blades. It provides gentle background blur on stopping down the aperture and a beautiful circular bokeh.

Focus Lock allows you to lock the focus ring in a specific position. This is especially useful when we want to maintain a specific distance to the subject (zone-focusing), or when we want to maintain perfect focus on infinity during landscape photography. Focus Ring - We know how much you liked the focus ring on the Irix DSRL lenses, that’s why we decided to use a similar one in our 45mm f/1.4 GFX lens. We have developed a ring material characterized by its high mechanical strength and resistance to adverse conditions. Special texturing allows for reliable and precise focusing, and dedicated embossed dimples allow you to feel the ring’s position even without looking for it- making focusing even easier.
