This versatile Pentax 35mm DA L F2.4 AL Lens is considered a standard, normal focal length lens for the Pentax DSLRs it was designed for, but it's a great lens to own, even if you only have one lens. This 35mm lens (equivalent to 52.5mm in 35mm format) is ideal for family photos, portraits, landscapes and a lot more. The fast f2.4 maximum aperture helps you get pictures even in low-light situations, and it provides high-resolution images with edge-to-edge sharpness. An aspherical lens element helps to compensate for spherical aberration to maximize image quality, and PENTAX Super Protect (SP) coating helps repel dust, water, and grease--making the lens easier to clean.
