Irix 11mm f/4 Blackstone - Pentax K
Irix 11mm f/4 Blackstone Pentax K is a manual-focus ultra-wide-angle prime lens with a fixed 11mm focal length and constant f/4 aperture. Built in the Blackstone finish, it is the heavier, more robust version in the Irix range, aimed at photographers who want strong construction and precise mechanical feel for landscape, architecture and interior work. The optic is known for its extremely wide field of view with controlled distortion for this class, plus a modern rendering that suits high-resolution DSLR bodies. Like other Irix lenses, it is designed for straightforward manual operation, so it rewards careful focusing and deliberate composition rather than fast action shooting. On Pentax K cameras it is a specialist lens for big perspectives, tight spaces and dramatic foreground emphasis, and it is especially useful when you want an ultra-wide look without moving to a zoom. Used-market checks should include smooth focus and aperture operation, clean glass with no haze, fungus or scratches, and the condition of the mount, caps and rear element; also confirm there is no damage from front filter-ring use or impact.
