Pentax HD D FA 150-450mm f/4.5-5.6 ED DC AW - Pentax K Mount

A long-reach telephoto zoom designed for wildlife and sports photography, featuring All Weather (AW) construction. The lens incorporates a DC motor for smooth autofocus and a focus range limiter to improve speed. It includes four extra-low dispersion elements to minimise chromatic aberration at longer focal lengths and a tripod collar for balanced mounting on a support system. Check the tripod collar for smooth rotation and secure locking. The zoom lock switch should function correctly to prevent lens creep when carried. SDS inspects the internal optics for fungal growth, particularly in used units from humid environments, and verifies that the autofocus remains responsive across the entire 150-450mm focal range. Verify the weather seals around the mount are intact.
