Description
A fast, standard zoom featuring a sophisticated optical design, the Pentax-D FA HD 24-70mm f2.8 ED SDM WR Lens is designed for use on full-frame K mount DSLRs, as well as APS-C cameras where it provides a 36-105mm equivalent focal length range. The constant f/2.8 maximum aperture offers consistent performance throughout the zoom range and pairs with a rounded nine-blade diaphragm to produce smooth shallow depth of field imagery. The lens’ design incorporates a trio of extra-low dispersion elements, three aspherical elements, and one anomalous dispersion aspherical element to control a variety of aberrations and distortions in order to produce well-corrected images with notable sharpness and even illumination. An HD coating has also been applied to further benefit working in difficult lighting conditions by suppressing lens flare and ghosting for increased contrast and colour neutrality.
