Irix 15mm f2.4 Ultra-wide Rectilinear Lens Announced

Swiss newcomers Irix look to leave a wide wake with their first entry into the 3rd party manual lens market.

The Photography Show 2016 in Birmingham,

Swiss lensmaker Irix have just announced their 15mm f2.4 ultra-wide manual focus rectilinear lens. Produced for Canon EF, Nikon F, and Pentak K Full-Frame mounts (look at you Pentax!) the new Irix 15mm f2.4 aims to capitalize on photographers desires for a high-resolution capable ultra-wide premium lens offering.

The new 15mm looks to set itself apart by packing in a list of dream features for fans of landscape, architecture and astrophotography. Most notably a good deal of attention was paid to precision manual focusing. The Irix 15mm f2.4 features a focus lock that can be selected at all focusing distances as well as a click-lock at infinity; the distance the lens will often live¬†at. That’s right astrophotographers, no more pre-focusing in the daylight then taping down your focus ring and hoping for the best. Speaking of shooting at night, the hyper-focal scale and other lens markings are said to glow in low light.

Minimum focusing distance is a very short .25 meters or .82 feet. Along with it’s f2.4 aperture this combo could make for some interesting out of focus effects as long as you’re willing and able to get very close to your subject. Should you need to stop the lens down it’s aperture design features 9 blades and a minimum f-stop of f22.¬†Irix_9_rounded_aperture_blades

Another nice touch not seen in other 3rd party options is that front filters are able to be screwed onto the massive 95mm filter thread¬†while maintaining the use of the lens hood. As if that weren’t enough there is also a slot for gel filters to be slid into place behind the rear element.

The 15mm f2.4’s¬†optical design utilizes¬†15 elements in 11 groups. With all of the modern corrective optics present Irix claims their lens will be capable of resolving the best of what modern 50+ megapixel sensors can capture. Elements feature a neutrino coating to help produce¬†an image free of outside coloration and maximize image contrast.

Because jumping into the market with a feature rich ultra-wide manual lens wasn’t challenging enough, Irix has decided to do so with two variations of the lens each aimed at shooters with different needs. First up is the Blackstone which lives in an¬†aluminium and magnesium body engineered to handle the environment with weather-sealing and splash resistance. Next is the Firefly designed for the more mobile photographer. It’s body is lighter and it’s focusing ring has a more knurled texture.

Irix says that it’s ultra-wide 15mm f2.4 will be available in the spring 2016 so we won’t have to wait long to see if the optics can match the body’s ambitious design. Pricing has¬†yet to be announced for this Korean assembled lens but expect it to fall between the Full-Frame offerings from Samyang/Rokinon/Bower and 1st party auto-focusing lenses.
