Irix has announced a new version of its 45mm F1.4 still lens, designed specifically for Fujifilm GFX medium-format cameras, which include the GFX100, GFX 50S, and GFX 50R

According to the release, the 45mm F1.4 GFX is fixed with a dedicated G-mount that covers the 54.7mm image circle found on the GFX series. It joins four other models in the still lineup.

Optically, the lens carries over much of the same construction as the full-frame 45mm F1.4 model available in Canon EF, Nikon F, and Pentax K mounts. The 45mm F1.4 GFX has the same 11 elements arranged in 9 groups with a single aspherical (ASP) and high refractive glass element to improve sharpness, along with multiple extra-low dispersion (ED) elements to reduce color fringing. 

The lens features the same 9 blade aperture that will create a smooth, rounded bokeh.  As for features, the lens also touts the company's focus lock feature that allows you to lock the focus ring to a specific position. 

The 45mm F1.4 GFX comes in its Dragonfly finish. This is different than Irix's other finishes—Firefly and Blackstone—that are found on the 11mm and 15mm.

The difference between those is that Firefly is a lightweight construction, and Blackstone is a full-metal design. Dragonfly is Blackstone on steroids. It has a reinforced internal construction, scratch-resistant finish, anti-slip focus rings, and seals to protect against water and dust. With the lens, Irix includes a carrying case. 

While the focus ring does not have standard 0.8m gears ideal for video shooters, it does have a non-slip surface allowing you to add standard pitch gears to the lens. If you're looking for dedicated cine lenses, Irix does have focal lengths available in 11mm, 15mm, 45mm, and 150mm for Canon RF/EF, Sony E, PL, and Nikon F, among other mounts. 

The 45mm F1.4 GFX will retail for roughly $795. It's available for pre-order now.
