This Pentax SMCP-FA digital lens provides quality shooting in a lightweight package. The Pentax camera lens weighs 7 oz, making it an easy option for travel and outdoor photography. The Pentax SMCP-FA features autofocus, as well as a manual focus. Photographers can alternate between focus modes with the slide of a switch to make adjusting focus faster. The wide-angle camera lens works with Pentax K mount cameras, though autofocus only works with specific cameras. With a prime focal length of 50 mm, this wide-angle camera lens is ideal for general photography as well. A f/1.4 aperture provides smooth out-of-focus edges for realistic portraits when using this Pentax camera lens. The lens imitates the view angle and perspective of the human eye for a more natural look. Additionally, the Pentax SMCP-FA has multi-layer lens coating to reduce reflections, as well as ultra-violet rays that can distort color. The coating helps preserve contrast and sharpness when shooting in any environment.
