Wide-Angle Prime Lens

The Pentax 15mm f/4 ED AL Limited is a fixed focal length lens for Pentax KAF-mount DSLR cameras. It delivers an expansive 86-degree angle of view, equivalent to 23mm in 35mm format. This wide perspective suits landscape, architecture and interior photography where capturing broad scenes is essential.

Optical Construction Benefits

Extra-low dispersion glass and a hybrid aspherical element work together to minimise flare and ghosting while maintaining sharpness across the frame. The high-grade multi-layer HD coating further improves light transmittance, ensuring vivid contrast and neutral colour rendition even in challenging backlit conditions.

Build and Mounting Practicality

The Limited Black finish identifies this as a premium variant within the Pentax lineup. Its KAF mount ensures direct compatibility with Pentax DSLR bodies without adapters. Photographers who need autofocus, zoom versatility or a faster maximum aperture should consider alternative lenses.

Questions about this item

Will the HD coating on the Pentax 15mm f/4 ED AL Limited Black Keepsake wear off and need re-coating?

The HD coating is a permanent multi-layer treatment on the glass surfaces; it does not wear off in normal use and never requires re-application.

What optical limit appears first when shooting wide-open at f/4 for long sessions?

At f/4 the lens is already at its maximum aperture, so the first limit you encounter is the fixed f/4 depth of field and any corner softness inherent to the 15 mm design.

How much heat does the Pentax 15mm f/4 ED AL Limited Black Keepsake generate during all-day landscape shooting?

As a purely mechanical prime lens with no electronics or motor, it produces no measurable heat of its own during extended use.
