With a fast f5.6 aperture, this apochromatic lens also incorporates an internal focusing system to give you fast, responsive autofocus speed. Polarizing filters are extremely easy to use with this lens because of its rotary filter holder, located in the rear part of the lens barrel. The lens materials used in this new lens are lead-free and arsenic-free ecological glass. This model is dedicated to Pentax AF SLR cameras.
