With a lens structure of 6 elements in 5 groups, it offers a magnification of 0.15x. The filter size is 52 mm, making it versatile for various photography styles.

## Long description

This medium-telephoto prime lens is designed exclusively for PENTAX K-mount interchangeable-lens digital cameras. With a large F1.8 maximum aperture and a round diaphragm, it delivers a shallow depth of field and natural bokeh, making it well suited for portraits and casual snapshots. The lens features PENTAX optical design optimised for K-mount sensors to reduce astigmatism and produce clear, sharp images. Its compact and lightweight construction makes it convenient for photographers at all skill levels.
Advantages
The large F1.8 aperture enables very shallow depth of field and allows faster shutter speeds in low light to reduce camera and subject blur. The round diaphragm creates a smooth, natural bokeh and minimizes streaking of point light sources. The front element is treated with PENTAX SP (Super Protect) coating to repel dust, water and grease and to allow easy removal of contaminants. The lens’s compact size and low weight make it easy to carry and handle during everyday shooting.

How to use
Mount the lens on a PENTAX K-mount camera body and set the desired aperture to F1.8–higher values to control depth of field. Use the large aperture for portraiture or low-light situations to achieve shallow depth of field and faster shutter speeds. Keep the front element clean; the SP coating facilitates wiping off dust, water and grease. For best results with portraits, focus on the subject’s eyes and position the subject away from the background to enhance bokeh.
Recommendations
Use this 76.5 mm equivalent, F1.8 medium-telephoto lens for portraits and casual snapshots. Rely on its SP coating in outdoor or variable conditions, and select wide aperture settings to achieve a pleasing background blur while monitoring shutter speed to avoid motion blur.
