HD PENTAX-DA645 28-45mm F4.5 ED AW SR is the first ultra-wide-angle zoom lens in the 645-system lens line-up that can be used on both 645Z and 645D. This is ideal for landscape photography, where delicate angle-of-view adjustments can be difficult due to the restricted footing, and for architectural photography requiring a wide angle of view despite the close distance to the subject.
