Key Specs
Lens Mount Compatibility: Pentax K-Mount
Lens Type: Standard Zoom
Minimum Focal Length: 17 millimeters (The minimum distance between the lens and the image sensor that allows the subject to be in focus. The shorter the focal length, the greater the area of scene captured.)
Maximum Focal Length: 50 millimeters (The maximum distance between the lens and the image sensor that allows the subject to be in focus. The greater the focal length, the smaller the area of scene captured.)
