IRIX Firefly 11mm f/4 Firefly 11mm
Its 16-element optical path with three aspherical and two ED elements, plus Neutrino coating, provides sharp, low-distortion images and a weather-sealed build at just 730g. The manual focus design features a rubberized ring, focus lock, and depth-of-field scale, offering precise control in a durable, weather-resistant ABS housing. This lens is ideal for Pentax K-mount users shooting ultra-wide landscapes and close-up details, given its 275mm minimum focus distance.
