Sony has revealed the Planar T* 50mm F1.4 and 70-400mm F4.5.6 G SSM II

Sony has revealed the Zeiss-branded Planar T* 50mm F1.4 ZA SSM and 70-400mm F4-5.6 G SSM II A-mount lenses, alongside a redesigned DT 18-55mm F3.5-5.6 SAM II entry-level kit zoom. The redesigned 70-400mm telephoto zoom offers faster autofocus than the existing version and comes in a white body that matches the recent 70-200mm and 500mm G lenses. Meanwhile, the 50mm F1.4 features a dust and moisture resistant design and quiet autofocus.

70-400mm F4-5.6 G SSM II” telephoto zoom

Sony’s G lens line-up is strengthened for 2013 with the revised 70-400mm F4-5.6 G SSM II. Ideal for capturing wildlife and action-packed sports, the upgraded super-telephoto zoom builds further on the premium performance of its predecessor with enhanced optics and faster, more responsive autofocus. Thanks to a new LSI drive circuit, autofocus speed of the SSM (Super Sonic Wave Motor) is around four times quicker than before. Teamed with enhanced tracking AF, the upgraded lens is now even more suitable for capturing stills and Full HD video of fast-moving subjects.

While its optical design is carried over from the previous-generation model, the new-generation lens features Sony’s proprietary Nano AR Coating on optical surfaces. Offering around five times the efficiency of conventional anti-reflection coatings, this advanced technology reduces flare and ghosting for exceptionally high-contrast images.

Carl Zeiss “Planar T* 50mm F1.4 ZA SSM”

The new Planar T* 50mm F1.4 ZA SSM joins the existing Distagon 24mm, Planar 85mm and Sonnar 135mm in the A-mount range of prime length optics by Carl Zeiss. Offering a fixed 50mm focal length and extra-bright F1.4 aperture, the premium lens is an ideal choice for quality-critical portraiture and low-light shooting.

Featuring 8 elements in 5 groups with two aspherical elements, the brand new optical design is optimised for superb results with Sony’s full-frame α99. Exceptional resolving power and contrast at all apertures are teamed with smooth, quiet autofocusing and a rear-focus system that maintains the same lens body length during AF. The dust- and moisture-resistant design extends the appeal of the new lens to a wide range of outdoor shooting applications.
