DA 18-250mm f/3.5-f/6.3 ED AL [IF] is a new interchangeable lens from Pentax (therefore, you should notice Pentax DA series is specifically designed for Pentax digital SLR cameras). The 14x super zoom lens features 27.5mm to 383mm (35mm equivalent) focal range and it is build upon 2 a-spherical optical elements in order to reduce aberration effects.
Compared to the other lenses in the Pentax product line, the new DA 18-250mm f/3.5-f/6.3 is not as compact as the DA 50-200mm f/4-f/5.6 ED, DA 12-24mm f/4.0 ED/AL [IF], or the DA Fish Eye 10-17mm f/3.5-f/4.5 ED [IF]. The Pentax 18-250mm lens weighs 1 pound and has an 3 x 3.4-inch body.
The minimum focusing distance is approx. 1.48-foot (0.45 meters) – based on mechanical Inner Focus (IF).
“Without the need for lens changes, it can be used for a wide variety of applications – ranging from such standard applications as landscape photography, snapshots, and portrait at frequently used focal lengths, to specialized applications like sports and wildlife photography at the super-telephoto range”.
The lens retails for $499.95 and will be available starting from October 2007.
