Designed for general photography, the new Olympus Zuiko Digital 12-60mm Pro lens is a high-performance standard wide zoom lens that is optimised for use with the E-3 DSLR camera. It features a splash-proof and dust-proof design and robust construction plus the Olympus Supersonic Wave Drive (SWD) lens drive mechanism that supports an ultra-fast, quiet and high-precision AF system.
Consisting of 14 Elements in 10 Groups, it includes one Super ED lens, three ED lenses (one of them Aspherical) and two Aspherical lenses, to ensure excellent colour reproduction and minimal image defects. Like other Olympus lenses, it has been developed specifically for digital reproduction and features a tele-centric style of design that should provide edge-to-edge sharpness, even at the widest apertures.
The lens barrel is solid, with a large zoom ring closest to the camera and a similar-sized focusing ring towards the front. Between them is a distance scale with feet and meter markings for focusing but no depth of field or infrared indicators. The scale has only four metre markings: 0.25, 0.4, 1 and infinity. Both rings are rubber-coated, with the zoom ring having a coarsely-textured surface, while the focusing ring is finely ridged.
Both zooming and focusing involve internal movement of lens elements and, although rotating the zoom ring causes the lens barrel to extend forwards, it does not change the angular orientation. This means angle-critical polarisers and graduating filters can be used without requiring constant re-adjustment when focus or focal length are changed.
A petal-shaped lens hood is supplied with the lens. It reverses along the barrel when the lens is carried or stored. The clip-on lens cap fits onto the front of the lens, attaching to an internal screw thread, which also accepts 72 mm filters. Supplied with the lens is a soft carrying case, which has an attachable shoulder strap.
