Combining a versatile normal focal length with fast design, the Canon EF-mount Irix 45mm f/1.4 is a useful prime lens characterized by its manual focus operation and weather-sealed design. The bright f/1.4 maximum aperture excels in low-light conditions and also offers increased control over depth of field for working with selective focus techniques. The optical design incorporates a series of specialized elements to reduce a variety of aberrations in order to produce sharp and color-accurate imagery.

Complementing the optical assets is a robust physical construction, dubbed Dragonfly, which incorporates extensive weather sealing to guard against dust and moisture. This manual focus lens also features a printed focus distance scale to benefit fast and accurate focusing, and a rounded nine-blade diaphragm contributes to a smooth bokeh quality.

Q: 7. For the Pentax mount version, will it work with a film Pentax camera like the ZX-5n which has Av and Tv settings or the fully manual K1000 SE? I understand that there is no aperture ring so I would not be able to select the aperture on a fully manual camera like the K1000 and the aperture would default to 22 which would be fine for my intended purpose (landscape photography with a large DoF mounted on a tripod). Was wanting this to use with a K-1 Mk II special for night sky astrophotography landscapes and also be able to use it with my old ZX-5n and a K1000 SE for daytime landscapes. I already have a 95mm night sky light pollution filter - which is why I would prefer this lens over the Roki 14mm 2.8 which won’t accept filters but does have an aperture ring and would likely work fine on my film camera.

A: It will mount to the older Pentax film cameras.
