Prime 60mm Pentax K-Mount lens is compatible with full-frame sensors as well as APS-C sensors, where it will provide a 90mm equivalent focal length.
The lens is capable of focusing on subjects as near as 2.4" away with a 2:1 magnification ratio for greater-than-life size macro shooting without the need of extension tubes or adapters. Additionally, the lens is also able to achieve infinity focus with a 1:10 magnification ratio for general shooting applications. When working with full-frame sensors, the image may be slightly vignetted when working at infinity focus.
Manual focus and manual aperture setting design does not maintain any electronic communication with the camera.
Nine-element-in-seven-group construction produces a high degree of clarity throughout the focusing range as well as accurate color rendering.
Two lens groups move during focusing in order to control barrel distortion.
Rounded 14-blade diaphragm produces a smooth out-of-focus quality when using selective focus or shallow depth of field techniques.
Built-in lens hood helps to deflect stray light from causing lens flare or ghosting.
All-metal lens barrel offers ensured durability and rigidity.
In addition to the lens itself, a protective filter pouch and a 62mm UV filter are also included.
