Closer Encounters With Sony's New 500mm Super-telephoto

Photographers can pull distant subjects closer with a new 500mm (equivalent to 750mm with APS-C camera) super-telephoto lens from Sony.

The SAL500F40G is ideal for sports, wildlife and demanding imaging applications that require extreme magnification.

The SAL500F40G is the longest fixed focal length G Lens from Sony to date. With a F4.0 maximum aperture, its excellent light gathering power allows the use of faster shutter speeds to broaden shooting opportunities.

Focusing ring and front/rear joints are protected by interlocking seals that shrug off dust and moisture.

Like all other A-mount lenses, the SAL500F40G is compatible with the SteadyShot INSIDE image stabilisation system that?s featured in every alpha Translucent Mirror and DSLR camera from Sony. Depending on shooting conditions, camera model and settings, you'll enjoy camera-shake blur compensation that's equivalent to approximately 4.5 stops (max.) in shutter speed.

Inside, the optical design of the SAL500F40G includes 11 elements in 10 groups, including three ED (Extra-low Dispersion) glass elements. It's also the first G Lens from Sony to feature a new coating process for clearer images. Exclusive to Sony, the Nano AR Coating process cuts internal reflections by up to 80% compared with previous models. Flare is reduced still further by the carbon fibre lens hood that?s lined with black velvet fibres to absorb incident light.

The high-torque SSM (Super Sonic wave Motor) features a new drive circuit for responsive AF with up to 4x faster object tracking than conventional Sony lenses.

Four focus hold buttons are spaced around the lens barrel for easy operation in any position. They're complemented by a two-way DMF (Direct Manual Focus) mode button and focus range switch for positive, fumble-free operation when you?re shooting under pressure.

The SAL500F40G super-telephoto lens from Sony will be available from late March 2012.
