IRIX Blackstone 11mm f/4 Blackstone 11mm
The 11mm focal length, constant f/4 aperture, and advanced optic layout with three aspherical and two ED elements ensure sharp, rectilinear images free of distortion, housed in a weather-sealed magnesium alloy body. A manual focus mechanism includes a focus lock, UV fluorescent engraved markings, and a rounded nine-blade diaphragm for precise control and smooth bokeh. This lens suits architectural and interior photographers who demand a rugged, weather-resistant ultra-wide prime for detailed, field-based work.
