New Lenses from Sony

Sony has announced four new lenses to accompany its new Alpha models. Aimed squarely at the first-time DSLR owners it's done so much to attract, all feature inexpensive construction (including plastic mounts) and a new in-lens autofocus system designated SAM (which stands for Smooth Autofocus Motor). First up is a pair of new kit zooms (standard and telephoto), in the shape of the DT 18-55mm F3.5-5.6 SAM and the DT 55-200mm F4-5.6 SAM. These are accompanied by a pair of primes; the DT 50mm F1.8 SAM and the DT 30mm F2.8 macro SAM. Prototypes of all four lenses were first shown at PMA earlier this year.
