Irix Firefly 15mm f/2.4-22 Ultra Wide Angle Lens with Built-in Chip for Pentax K Digital SLR


The Irix 15mm Firefly is a manual, super-wide-angle lens that allows you to include much more of the scene for a greater sense of space and incredible effects. It's the perfect lens for landscape, architectural and even interior photography. This versatile lens will adapt to every situation and the results are impressive, to say the least. The built-in hyperfocal distance scale gives you precise information about the depth of field for each shot. The ergonomic focusing ring incorporates a convenient click-stop for the infinity setting. An innovative focus lock lets you easily set the focus anywhere on the scale and keep it there for consistently repeatable results and to help avoid focus drift. With a minimum focusing distance of 11.02" (0.28m), you can get in close to your subjects for great wide-angle effects.
