Pentax 55mm f/1.4 DA* SDM Short-Telephoto Lens

The Pentax 55mm f/1.4 DA* is a prime short-telephoto lens built for the Pentax K mount, designed specifically for APS-C format digital SLR cameras. With a maximum aperture of f/1.4, it gives photographers meaningful control over depth of field and performs well in lower light conditions where slower lenses struggle. The 55mm focal length sits in short-telephoto territory on APS-C bodies, making it a natural choice for portrait work and everyday shooting where a slightly tighter field of view is preferred over a standard focal length.

Autofocus is supported alongside full manual focus capability, giving shooters the flexibility to switch between focusing modes depending on the situation. The lens accepts 58mm filters, which opens up a broad range of compatible accessories. At 375g, it strikes a reasonable balance between build substance and portability — substantial enough to feel well-constructed without becoming a burden during extended use.

The lens is compatible with Pentax K mount camera bodies and is categorized within the DA* lineup, which represents Pentax's higher-tier optical series. There is no image stabilization built into the lens itself, though many Pentax bodies feature in-body stabilization systems. Overall, this is a purposeful prime lens aimed at Pentax DSLR shooters who want a fast aperture in a compact short-telephoto package.
