The Pentax 20-35mm f4 SMC FA AL Lens covers angles of view from an ultra-wide 94° at the 20mm setting to a wide 63° at 35mm. The Pentax 20-35mm Lens incorporates two aspherical lens elements to reduce distortion and produce sharp, crisp image reproduction. Like all Pentax FA lenses, the Pentax 20-35mm Lens is treated with Pentax’s acclaimed SMC coating for maximum light transmission, sharp definition, and high contrast, while minimising flare and ghost imaging. Extremely flexible, the Pentax 20-35mm Lens is ideal for shooting panoramic landscapes and tall buildings.
