The Pentax SMC-DA 15mm f/4 ED AL Limited is a new so-called pancake lens for Pentax APS-C DSLRs. The field-of-view of this lens is equivalent to about 23mm so it's on the verge of being a wide to ultra-wide prime lens. As you can observe below pancake lenses are pretty tiny beings - this one has a length of just 40mm. Pentax has quite a tradition here by now and these lenses are definitely a differentiator compared to other systems.

Lens Mount
The Pentax DA 15mm f/4 Limited prime is offered only in the Pentax KAF2 lens mount, a modernization of the long-lasting Pentax K mount. With a crop factor of 1.5x on DSLR cameras, the lens has a 35mm equivalent range of 23mm.
Manual Focus
Focusing manually with the Pentax DA 15mm Limited lens is much easier than with older Pentax lenses. As with all lenses in the DA family, there is no need to flip the MF/AF switch on the lens barrel or camera body because this lens features "quick-shift focus" (full-time autofocus override)
