Description — Pentax Macro 100mm f/2.8 ED AW
The Pentax HD Pentax-D FA Macro 100mm f/2.8 ED AW is a prime macro lens designed for the Pentax K mount, covering a full-frame image circle and fitting comfortably within the telephoto focal length range. With a fixed focal length of 100mm and a maximum aperture of f/2.8, it offers a solid combination of reach and light transmission for macro and detail-oriented photography. The lens supports both autofocus and manual focus operation, giving photographers the flexibility to choose their preferred focusing method for any given situation.
A 49mm filter thread keeps accessory costs reasonable, and the lens's 345g weight makes it practical for field use without adding excessive bulk to a DSLR kit. Image stabilization is listed as None in the specifications, so in-body stabilization from the camera body is the available option for shake reduction. This is a purpose-built macro prime built exclusively for Pentax K mount DSLR systems.
