Pentax FA 645 400mm f/5.6 EDIF Lens

Code: 26555    Brand: Pentax   

Extra-low dispersion (ED) glass is used for thoroughly eliminating the chromatic aberration that tends to occur in super telephoto lenses. This enables a sharp resolution with a minimum of color blurring. Various types of protective coatings, prevention of reflections on the inner side of lens, and a large hood are used for rendering results with a transparency and reduced ghosting and flare.

The smc FA 645 400mm f/5.6 ED IF Lens from Pentax is a medium format, manual and autofocusing telephoto lens with a 35mm-equivalent focal length of 315mm. Extra-low dispersion (ED) glass is used to eliminate chromatic aberration for improved sharpness and contrast. Multi-coatings offer protection and prevent reflections on the inside of the lens to minimize ghosting and flare. Also helping to prevent flare is the supplied large lens hood. Quick AF/MF switching is also possible, and an internal focusing system enables easy MF operation and improves focusing speed while minimizing lens extension, allowing for a closer minimum focus distance. Additionally, the lens features a rotating tripod collar with clip to enable speedy switching between vertical and horizontal orientations.
