Key Specs
- Lens Mount Compatibility: Pentax K-Mount
- Lens Type: Macro
- Minimum Focal Length: 18 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.)
- Maximum Aperture: f/3.5 (The limit to how wide a lens can be open, typically expressed in f-numbers. The smaller the number, the larger the aperture and the more light that can enter the lens. A larger aperture creates a shallower depth of field, helpful for keeping subjects in focus and blurring background details.)

This zoom lens was exclusively designed to suit the characteristics of digital SLR cameras. The image circle was designed to match the size of the image sensors of digital SLR cameras, and this produced a compact lens with a maximum diameter of 60mm (2.3in.), overall length of 67.5mm (2.6in.) and weight of only 245gr (8.6 ounces). It has a variable angle of view of 69.3degree~27.9degree. The use of aspherical lenses provides correction for various aberrations throughout the entire zoom range and produce high level of optical performance. 18-50mm F3.5-5.6 DC lens has a minimum focusing distance of 25cm (9.8in.) at all focal lengths and is capable of macro photography with a maximum magnification ratio of 1:3.5.
