Irix 45mm F1.4 Review Posted
By bdery in Review Announcements on Mar 23, 2021
Today we are happy to present our in-depth review of the Irix 45mm F1.4 lens!
Launched in 2020, this fast aperture, normal lens features a rugged, weather-sealed body, automatic aperture coupling, manual focus with adjustable friction and a focus lock.
The focal length makes the Irix a logical competitor to the Pentax 43mm F1.9 Limited, while its size and specifications bring it more in line with the D FA* 50mm F1.4.
How does the Irix compare with these lenses, and with other modern 50mm lenses available on K-mount? Read our review to find out!
