This smc PENTAX-DA 50mmF1.8 short telephoto lens uses a bright open F value and round iris dia-phragm for enabling attractive out-of-focus (bokeh) effect.

This short telephoto lens uses a bright open F-value and round iris diaphragm for enabling attractive out-of-focus (bokeh) effect. A plastic mount is used to enable high cost performance and a more compact and lightweight design. With this lens, you can easily enjoy shooting of portraits, snapshots, and other situa-tions.

Short telephoto lens suitable for portrait and snapshot photography
When attached to a PENTAX K mount digital SLR camera, this lens provides a focal length equivalent to 76.5mm in the 35mm film format. This enables unique enjoyment of photography that is only possible with short telephoto lens, such as portraits with an out-of-focus (bokeh) background and snapshots where a portion of the subject has been removed.

Bright open aperture
An open F1.8 large aperture F-value is used to enable photographic representations that use an extremely shallow depth of field.

Bokeh effect
This lens uses a round diaphragm for reducing the beams of light when shooting point light sources for enabling a soft, natural out-of-focus (bokeh) effect. This enables shooting at high shutter speeds even in dim locations for reducing the adverse effects of hand shaking.

Compact, lightweight design
Featuring a compact, lightweight design with a length of 38.5mm and weight of only 122g for enabling enjoyment of carefree shooting and easy portability

Impressive delineation performance

The newest optical design is used, and the image circle is optimized for the imaging element size for providing delineation performance where non-point aberrations are corrected.

SP (super protect) coating
Also, the lens front surface uses the SP (super protect) coating for repelling water and oils. This prevents dirt and dust from adhering to the lens and enables them to be easily removed so that you can carry around this lens with peace of mind.

PENTAX K Mount

The lens mounts for PENTAX interchangeable lenses are based on the bayonet K mount, which has remained unchanged since its inception in 1975. It is a mount unique to PENTAX that features a large aperture combined with superior ease of replacement, accuracy, and toughness. These features are utilized to comfortably incorporate an iris control mechanism, autofocus mechanism, and other functions for enabling nearly complete compatibility with conventional lenses. The PENTAX K Mount keeps its advanced versatility despite differences in camera and lens functions.
