The smc-DA series of lenses are particularly developed and designed for use with PENTAX digital cameras. They are designed to fulfil the high digital image technology standards of PENTAX digital SLR cameras and are intended exclusively for use with these cameras. Extreme focal lengths are the domain of SLR photo¬graphy. With the 12 – 24mm zoom lens PENTAX has succeeded in mastering a difficult challenge and can now offer wide angle photography on the highest digital level. With the 35mm equivalent of an 18 – 36mm lens, breath taking photographs are possible even if the spatial surroundings are limited.
