Description — Pentax 24-70mm f/2.8ED SDM WR
The Pentax HD Pentax-D FA 24-70mm f/2.8ED SDM WR is a standard zoom lens covering 24mm to 70mm with a constant f/2.8 maximum aperture, designed for the Pentax K mount and optimized for full-frame DSLR cameras.

The lens supports both autofocus and manual focus, offering flexibility across different shooting scenarios.
Its 82mm filter thread accommodates a full range of large-format filter accessories.
