Description — Pentax 70-210mm f/4 ED SDM WR
The HD PENTAX-D FA 70-210mm f/4 is a full-frame telephoto zoom lens built for the Pentax K mount DSLR system. It spans a 70–210mm focal length range and holds a constant f/4 maximum aperture throughout, so there's no exposure shift as you zoom — a meaningful advantage when shooting quickly or in mixed light. The lens supports both autofocus and manual focus, giving you the control you need for a variety of subjects.
A 67mm filter thread makes it straightforward to attach polarizers, ND filters, or protective UV glass. The lens weighs 819g, placing it in a practical range for a full-frame telephoto zoom while still being a considered carry for longer shoots. Designed specifically for the Pentax K mount camera system, it integrates natively with compatible Pentax DSLR bodies.
Note that no image stabilization is built into the lens, so shooting technique, in-body stabilization, or support equipment becomes more important as you approach the longer end of the zoom range.
