Pentax 10-17mm digital fish eye zoom unveiled - Pentax have announced the smc Pentax DA fish-eye 10-17mm f/3.5-4.5 ED [IF] lens. Designed exclusively for use with the Pentax line of digital SLRs, this interchangeable lens offers fish-eye (180° diagonal angle of view at a focal length of 10mm) to super wide-angle performance in a single unit.
The image circle of this new lens will match the image recording area (23.5mm x 15.7mm) of the *ist D series to ensure precise optical performance ideally suited to the camera's digital imaging characteristics. The smc Pentax DA FISH-EYE 10-17mm F3.5-4.5 ED [IF] lens design also features lightweight, compact dimensions compared with 35mm format, SLR interchangeable lenses with equivalent specifications.
High Optical Performance. Employing ED (Extra-low Dispersion) glass, this lens compensates for chromatic aberration throughout the image. And with new optical architecture and a ghost-free lens coating, ghosting and flare are suppressed to produce clear, high-quality images more of the time.
Super macro shooting. The advanced internal focus system allows photographers to focus from as close as approximately one inch (2.5cm) with the power to fill the whole frame with surprisingly small subjects.
Newly Developed SP Coating made of a special fluoride compound has been applied to the front surface of the lens with a unique evaporation process. As a result, the lens offers excellent water and oil-repellant performance and makes for easier cleaning.
Exclusive Pentax Quick-Shift Focus System for instant shift to manual focus once the subject is captured by AF.
Durable metallic lens mount.
Exclusive lens cap constructed from high-quality aluminum.
