Le communiqué de presse
PENTAX EXTENDS LENS RANGE FOR DIGITAL SLRS
Five new lenses are announced to supplement the existing range of accessories for digital SLR cameras.
The two new fast telephotos smc PENTAX-DA* 200mm F2.8 ED [IF] SDM and smc PENTAX-DA* 300mm F4.0 ED [IF] SDM are not only optically astounding but also support the ultrasonic autofocus drive system for fast and quiet operation.
Special optical glass including ED glass elements, aspherical lens elements and outstanding lens coating provide for excellent contrast characteristics, a consistent edge-to-edge sharpness and a particularly clear rendition of fine details.
As well as the outstanding imaging attributes, PENTAX engineers have raised the mechanical characteristics of the lenses to a state-of-the-art level. Built-in ultrasonic motors (Supersonic Motors) in the lenses provide for extremely quiet and fast autofocusing. Both lenses are also weatherproofed and protected from penetrating dust by appropriate seals. The front lens elements of the lenses use the special Pentax SP - "Super Protect" - fluoride coating technology. This nano-technology protects the front lens against dust, finger marks or smearing, making the lenses exceptionally easy to clean. The Pentax "Quick Shift Focus System" allows the photographer to manually alter the focus point at will without having to take the camera out of the autofocus mode.
The new smc PENTAX-DA 35mm F2.8 Macro Limited Lens will satisfy the most demanding photographer with its pictorial quality. Due to its fast aperture and outstanding sharpness this lens is ideal as an everyday ‘standard lens’.
Two zoom lenses; the smc PENTAX-DA 18-55mm F3.5-5.6 AL II and the smc PENTAX-DA 55-300mm F4-5.8 ED complete the new PENTAX lens assortment. With their compactness and extended zoom range they are both well suited for all types of general photography. The SP - "Super Protect" - technology and the PENTAX "Quick Shift Focus System" are incorporated in both lenses. ED glass lens elements are used in the optical construction of the smc PENTAX PENTAX-DA 55-300mm F4-5.8 tele-zoom in order to assure the highest image quality possible.
(The SDM (Supersonic Motor) system can only be used with PENTAX K10D and K100D Super. All other PENTAX DSLR cameras use the AF drive system incorporated in the camera body.)
