To go along with the K20D and K200D, Pentax announced five lenses that range from 18mm to 300mm.
Without getting into exact specifics since I know most of you don’t care, I’l touch on a few key things. The 200mm f/2.8 and 300mm f/4 lenses have Sonic Drive Motors, which basically ensure quiet and fast focusing as well as weather resistant and dust resistant bodies. The 35mm f/2.8 Macro Limited has a fast aperture. The 18-55mm and 55-300mm lenses have been spruced up with the quick-shift focus system and super protect coating to protect the exposed lens elements. Also featured on the 55-300mm lens is ED elements to help compensate for chromatic aberrations.
