Description PENTAX-FA 50mm F1.4 Large Aperture HD Coating Contemporary Design Lens (Black Matte Finish) The HD PENTAX-FA 50mm F1.4 Lens is designed for use with the PENTAX K-mount digital SLR cameras. Offering a unique design concept, this compact standard lens lets photographers choose the lens that suits their style and use. Drawing inspiration from the iconic 1991-launch PENTAX-FA 50mm F1.4 lens, this contemporary counterpart incorporates large-diameter optical elements to fully cover the full-frame image circle of K-mount cameras. Latest High-Grade HD Coating The HD PENTAX-FA 50mm F1.4 lens features a high-grade, multi-layer HD coating that delivers sharp images with high contrast. The newly revamped design looks similar to the contemporary DA- and D FA-series lenses, which makes it an ideal match for the new PENTAX digital SLR cameras. Extensive Research to Achieve Improved Images The multi-layer HD coating of the lens was incorporated after extensive research of the lens coatings applied to the smc PENTAX-FA 50mm F1.4 lens. This new implementation has resulted in a reduction in average reflectance. It not only improves light transmission but also effectively diminishes ghosting and flare to deliver crystal-clear images with high contrast. The photographer can experience a drastic reduction in ghosting even in the worst scenarios with backlighting. Contemporary Design Although the lens is based on the iconic smc PENTAX-FA50mm F1.4 lens, this lens has a new and contemporary exterior design similar to the DA- and D FA-series lenses, which makes it an ideal match for the SLR cameras of the K-series. Multipurpose Use Mount it on a PENTAX digital SLRcamera body to use it as a standard 50mm lens in the full-frame format, or use it in the APS-C format to make it a 76.5mm medium-telephoto lens. When used with a full-frame camera, it provides an angle of view close to the human visual field. This makes it an ideal choice for a range of applications, from shooting portraits, scenes, or just plain snapshots. Shallow Depth of Field Experience a very shallow depth of field with the lens’ large F1.4 open aperture. Easy Maintenance The lens features a water- and grease-repellent SP (Super Protect) coating on its front surface. This makes it easy to wipe away water and stains. Eight-Blade Diaphragm Control Mechanism Give your pictures a soft and subtle, natural-looking bokeh effect thanks to the eight-blade diaphragm control mechanism of this lens. It lets you further minimize the streaking effect of point light sources. Compatible Design The lens is compatible with K-mount digital SLR cameras from the past and film-format AF SLR cameras. The aperture ring on the lens body lets the photographer keep all camera functions intact. The versatile mechanism is made to work with the camera’s motor-driven, in-body AF system.
