Compact prime for Pentax shooters

The HD Pentax-FA 31mm f/1.8 Limited is a wide-angle prime lens built with a machined aluminum body and a fixed hood. Its HD coating reduces ghosting and flare for high-contrast images, while the rounded nine-blade diaphragm produces smooth background blur at the f/1.8 maximum aperture.

Street and portrait photographers wanting

On APS-C bodies the lens gives a 47.5mm equivalent perspective that suits everyday scenes and environmental portraits. Photographers who need zoom flexibility or telephoto reach should consider other optics, as this is a single-focal-length design.

Consistent rendering during extended sessions

The all-metal construction resists heat buildup and maintains focus stability when shooting for long periods. HD coating performance remains constant across varying light, so contrast and colour fidelity do not degrade as the lens warms up.

Questions about this item

What camera mount does this 31mm f/1.8 Limited lens need to attach to?

It uses the Pentax K mount, so you must own a Pentax K-mount body or an adapter that accepts K-mount lenses.

Will the 31mm focal length give the same field of view on my older Pentax film body as on a current APS-C model?

On a film or full-frame body it acts as a true 31mm wide-angle; on APS-C it becomes a 47.5mm equivalent, so the angle of view narrows.

How can I confirm the HD coating is cutting flare after I mount the lens?

Shoot into a bright light source; clean highlights and no coloured ghosting mean the HD coating is performing as designed.
