Key Specs
- Lens Mount Compatibility: Pentax K-Mount
- Lens Type: Telephoto Zoom
- Minimum Focal Length: 70 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: 300 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.)
