					  !@ PENTAX DA 10-17mm f/3.5-4.5 ED (IF) Fish-Eye Lens for Pentax Digital SLR




Capture fisheye imagery with a 180-degree angle of view with the Pentax DA 10-17mm fisheye lens.
Designed for the Pentax *ist series of digital SLR cameras, the lens creates images with an expanded
perspective, including images with a creatively deformed outlook and a sharp pan focus that extends
throughout the entire frame. The image circle in DA series lenses, meanwhile, is designed to perfectly
match the 23.5 x 15.7mm size of the CCD used in Pentax digital SLRs to optimize camera
performance. Plus, the new design contributes to a drastic reduction in size, weight, and production
cost compared to 35mm counterparts with similar specifications. Additional features include a 35mm
equivalent focal length of 15-26mm; new water- and oil-repellant super-protective (SP) lens coatings
for easy cleaning; extra-low-dispersion (ED) glass for superior sharpness and color correction; and a
responsive Quick Shift Focus System for switching instantly from autofocus (AF) to manual focus (MF).
