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. Whether shooting wide environmental scenes at 24mm or moving to tighter 70mm framing for portraits and detail shots, the consistent f/2.8 aperture means your exposure and depth-of-field behavior remains predictable throughout the zoom range. 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. Weighing in at 790g, this is a solidly built optic suited to professional and enthusiast Pentax DSLR shooters who need a reliable, fast-aperture zoom covering the most-used focal length range. Note that this lens does not include optical image stabilization, so stabilization-dependent shooting in low light will rely on other means.
