Offering flexibility in a compact package, the K-mount HD PENTAX DA 18-50mm f/4.0-5.6 DC WR RE Lens from Pentax features a retractable design which significantly shortens the lens when not in use, and has a versatile 35mm equivalent focal length of 27.5-76.5mm when used with APS-C cameras. The aperture is variable with a range of f/4.0-5.6 when wide open, and the lens utilizes aspherical lens elements to ensure edge-to-edge sharpness throughout the zoom range. Also, it utilizes both the HD PENTAX coating for limiting flare and ghosting for excellent contrast in your images as well as a Super Protect coating to ensure the lens elements aren't easily damaged or scratched.
Smooth, quiet autofocus is possible with the use of a direct current (DC) motor and it has the Quick-shift focus system for quickly switching to manual focus. The lens also has ten seals as part of the all-weather resistant construction, limiting potential damage from water, moisture, and dust. Additionally, it has a rounded 7-blade diaphragm and comes with a hood and lens caps.
