Product description
Announced Feb 20, 2018

The Irix 11mm F4 manual focus lens comes in two 'flavors': the 'Firefly', which is the basic model and the 'Blackstone', which has a higher build quality and premium finish. Constructed using 16 elements arranged in 10 groups the lens offers a nine-bladed iris with apertures from F4 to F22. Electrical contacts allow users to control aperture values from the camera body and for aperture values to be recorded in EXIF data. It's available in mounts for Canon, Nikon and Pentax.
