## Description

smc PENTAX-FA 50mmF1.4 Classic, single-focus, standard lense for use with K-mount digital SLR cameras

## Features

- Through intentional fine-tuning of the lens design, this lens has been designed to produce a unique visual effect commonly known as rainbow flare when it captures an image at open aperture* and against strong backlight. By closing the aperture down to F4 or smaller, the photographer can capture sharper, crisper images that are free of not only rainbow flare, but also ordinary flare and ghost images.
- This lens retains the exterior design of the smc PENTAX-FA50mmF1.4, featuring a black matte finish and a matte-black focus ring. It has no green ring — the symbolic design of recent PENTAX digital-specific lenses — to recreate the nostalgic appearance of an old-time lens from the film-format SLR era.
- When mounted on a PENTAX digital SLR camera body, lense can be used as 50mm standard lenses in the full-frame format, or 76.5mm medium-telephoto lenses in the APS-C format.
- The large F1.4 open aperture produces images with a very shallow depth of field.
- Water- and grease-repellent SP (Super Protect) Coating has been applied to the front surface of the lenses, making it easier for the user to wipe off water or stains.
- The eight-blade diaphragm control mechanism produces a soft, natural bokeh (defocus) effect from open aperture to F2.8, and also minimizes the streaking effect of point light sources.
- Designed to be fully compatible with older K-mount digital SLR cameras and film-format AF SLR cameras, these lenses allow the photographer to retain all camera functions, thanks to the aperture ring installed on the lens body, and the mechanism designed to couple the lens with the camera’s motor-driven, in-body AF system.
