The maximum aperture of the HD Pentax-FA 31mm f/1.8 Limited Lens is f/1.8, making it ideal for low light conditions and depth of field control.
The PENTAX-original HD coating is a high-grade coating that assures higher light transmittance compared to conventional multi-layer coatings. This results in sharp, clear images free of flare and ghost images, even in challenging lighting conditions.
The bokeh effect is a visually pleasing aesthetic in photography where the lens renders out-of-focus points of light. The HD Pentax-FA 31mm f/1.8 Limited Lens produces a beautiful, natural bokeh effect.
The Super Protect (SP) coating is applied to the front surface of the lens to repel dust and stains, ensuring the longevity of your lens.
The HD Pentax-FA 31mm f/1.8 Limited Lens is designed to be used with Pentax K-mount cameras. It is compatible with a wide range of Pentax models, including the Pentax K-1, Pentax K-1 Mark II, Pentax K-2000, Pentax K-3, Pentax K-3 II, Pentax K-30, Pentax K-5 IIs, Pentax K-50, Pentax K-500, Pentax K-7, Pentax K-70, Pentax K-S1, Pentax K-S2, and Pentax KP.

Very good lens, sharp details and no signs of edge softness, slight flair on back-lit subjects can be an issue

This is an update to one of the legendary Pentax Limited Full-Frame lenses, with the addition of improved modern HD coatings (for less flare) and curved aperture blades. This is an excellent lens, beautiful bokeh, great low-light performance, and that ?Magic Pixie Dust? 3-D effect that combines amazing sharpness with smooth out-of-focus transitions and great color rendition. This is my favorite lens; it is my standard lens on APS-C. Highly recommended
