소니 알파 Sony E-mount 20mm F2.8 pancake prime lens

 Sony has announced the E 20mm F2.8 - a moderately wide-angle pancake prime lens for its NEX cameras. The moderately-fast E-mount pancake will offer a 30mm equivalent field of view and adds another compact lens option for NEX shooters. It will be available in April for around $350. Sony has also said it will offer its video-targeted 18-200mm OSS F3.5-6.3 power zoom lens as a standalone product. Previously only available bundled with the NEX-VG30 camcorder, it becomes the company's third E-mount 18-200mm superzoom and will cost around $1200.

SAN DIEGO, Jan. 22, 2013 – Sony is expanding its popular E-mount camera system with the addition of two new lenses compatible with all α E-Mount cameras and semi-professional camcorders.

New 20mm F2.8 ‘pancake’ wide angle lens (model SEL20F28)

When mounted on any Sony α E-Mount camera, the sharp new SEL20F28 ”pancake” lens creates an exceptionally versatile, portable package ideal for a broad range of everyday shooting opportunities ranging from interiors to landscapes, street photography, casual snapshots and more.

The new lens features an ultra-slim design approximately 20mm from lens front to back, and with its wide angle of view (30mm on 35mm equivalent) and bright F2.8 aperture, it produces excellent contrast, resolution and clarity across the frame for both still image and full HD video shooting.

New 18-200mm F3.5-6.3 OSS Powered Telephoto Zoom Lens (model SELP18200)

Originally offered only as a kit lens for the new NEX-VG30 camcorder introduced this past fall, the new SELP18200 powered telephoto zoom lens will now be available for purchase as a stand-alone lens.

Designed for serious videographers, the high-quality lens offers a generous 11x magnification range and whisper-quiet power zoom mechanics, focusing and aperture operation. This allows for smooth cinematic transitions when adjusting zoom level or manual settings during shooting. It features a comfortably positioned zoom lever that works with a switch on the lens barrel, allowing zoom speed to be selected in three different steps – from slow, beautiful shifts in perspective to dramatic crash-zoom effects. Zoom can also be controlled directly from compatible NEX-VG900, NEX-VG30 and NEX-FS700 (requires firmware update) video cameras.

The new lens also has built-in Optical SteadyShot™, which cuts the effects of camera shake and minimizes camera blur while shooting handheld at slower shutter speeds. Additionally, Active Mode further enhances stabilization at the wide end of the 11x zoom range ensuring smooth, stable footage even if the shooter is in motion.

While the new SELP18200 lens is optimized for video, it’s also a flexible choice for shooting still photography – from expansive landscapes to high impact close-ups of wildlife or athletes – with Sony’s α E-Mount range of interchangeable lens still cameras.
