Review Summary

The lens is razor sharp. At F1.4 the depth of field is paper thin. I use " catch in focus" method and the firmness of the focusing barrel is a plus IMO. It's heavy and well built, and the balance was good with my K-1. I'm an old 2 1/4 film shooter so I'm used to working at a slower pace and manually focusing. If you are in a hurry I can not recommend. If you are patient and like to craft your images in camera, you will be very pleased.

Lens is phenomenal for astrophotography. Not as wide as some would like but still phenomenal. Paired with my Nixon D810 images are sharp and clean. Very well built and heavy lens for the price. You can't beat it for a 500 dollar lens.

Irix 45mm F1.4 old school sharpness.

Smooth Bokeh | Fast Aperture | Classic Focal Length
The Irix 45mm f/1.4 is a compelling alternative to 35 and 50mm focal lengths, thus providing a creative option for all fans of "normal" lens photography.
Whether you're a professional photographer looking for the right lens for the job or an amateur looking to fill a gap in your focal lengths - the Irix 45mm F/1.4 is the lens for you!
Focus Lock
The Focus Lock feature allows you to lock the focus ring in a specific position. This is especially important for landscape photos and repetitive shooting as well as when you want to keep a specific distance from the subject (ie. In-studio or on the street).
Focus Ring
Due to the excellent response from Irix shooters to the focus ring we designed for the Irix 150mm f/2.8 1:1 Macro lens, we incorporated a similar one in our Irix 45mm f/1.4 lens. After extensive testing, we have developed a material that provides excellent durability and resistance to weather conditions and which, combined with special embossing, provides outstanding comfort. You'll find that the "feel" of the hand position on the ring makes focusing even easier.
Ready to Shoot in Any Weather
The best lenses must provide ease of use in all lighting and atmospheric conditions. The Irix 45mm f/1.4 provides for this with laser-engraved focus and aperture markings, filled with UV-reactive paint. This innovation makes them readable even in low-light conditions. Irix weather sealing also assures the reliability of our lenses, protecting the lens interior and the camera sensor from dust and moisture, regardless of the environment and weather.
This lens is equipped with weather sealing in four key places to protect the internal parts from unfavourable weather conditions so there are no worries to use it even in harsh environment and weather conditions.
Build Quality - Dragonfly
The Dragonfly finish is the perfect blend of strong metal components and lightweight composite materials. In addition to its rugged construction, the lens is also weather sealed at crucial points, for worry-free use in all environments and weather conditions. Its internal focusing mechanism means it keeps its compact size as you concentrate on the shot.
