SAL-135F28 135mm f/2.8-4.5 Telephoto Lens

The advanced SAL-135F28 STF (Smooth Transition Focus) telephoto lens incorporates an apodization optical element that distributes light rays to create smooth, aesthetically pleasing out-of-focus backgrounds and foregrounds that make sharp-focus subjects stand out more vividly. Mounted on your Sony (alpha) DSLR-A100 camera, this lens provides a 200mm focal length (35mm equivalent).

Smooth Transmission Focus
While subjects remain in sharp focus, out-of-focus backgrounds or foregrounds are blurred smoothly and evenly with gradation that thickens toward the edges of the frame for a pleasing aesthetic effect

Transmissive Brightness
After light passes through the apodization element, the lens aperture of f2.8 yields a T (transmissive brightness) equivalent of 4.5; a manual aperture ring can adjust T setting from 4.5 to 6.7.

Wide Focus Ring
The dedicated manual focusing system is controlled by a wide focus ring that’s comfortable to hold and gives you a solid, hands-on feel for pinpoint focusing of your subject.

Circular Aperture
Because aperture blades form a near circle at the wide openings used for low-light shots, spot-light sources have a pleasing circular defocused effect.

SAL-2470Z 24-70mm f2.8 Zoom Lens

High-performance Carl Zeiss large-aperture zoom. The SAL-2470Z Carl Zeiss Vario-Sonnar f2.8 24-70mm Zoom Lens is a brilliant all-around performer—with SSM (Super Sonic wave Motor) design for fast, silent auto-focus, pro-quality Carl Zeiss T* coated optics to reduce lens flare, and 17-element design with two aspherical and two ED glass lens elements to minimize distortion and virtually eliminate chromatic aberration. It also benefits from the Super SteadyShot image stabilization built into every Sony system DSLR—and its wide-angle to medium telephoto range and compact, lightweight design is ideal for a wide range of shooting applications (35mm equivalent: 36-105mm).

Compact Design, All-Around Versatility
This superb 24-70mm zoom lens is an excellent choice for a wide range of photo applications — a lens you can put on and leave on, providing large-aperture brightness that’s easy to carry (35mm equivalent: 36-105mm).

Superior Large-Aperture Performance
Like other large-aperture Carl Zeiss lens designs, this f2.8 24-70mm zoom lens is simply magnificent in its ability to capture brilliant high-resolution images in low-light conditions requiring fully open aperture.

In-Camera Image Stabilization
A major reason for its compact, lightweight design is the benefit of Super SteadyShot in-camera image stabilization, built into every Sony ? system DSLR — and enabling accessory lenses to eliminate the extra weight and expense of in-lens stabilization mechanisms.

SSM (Super Sonic wave Motor)
Designed for fast, smooth, silent automatic focusing, this unique technology achieves high torque at low speed with rapid start/stop response. It operates through the ability of a piezoelectric device to reshape itself quickly when voltage is applied.

Carl Zeiss T* Coating
Coated optics were pioneered by Carl Zeiss — and this superb lens features T* (T-Star) coating that virtually eliminates the lens flare, internal reflection and light scattering that can otherwise occur at glass-to-air surfaces.

Multi-Element Design
The SAL-2470Z is designed with 17 lens elements in 13 groups, including 2 aspherical elements and 2 ED glass elements. Floating motion between the third and fourth groups of lens elements helps compensate for any aberrations caused by the zooming action of the lens.

Glass-Molded Aspherical Lens Elements
These precision lens elements correct distortion for sharper, more visually accurate images across the entire zoom range of the lens.

ED (Extra-low Dispersion) Glass
Because light of different wavelength (or color) bends at different angles when it passes through a lens, ED (Extra-low Dispersion) Glass is used in Carl Zeiss lenses to eliminate chromatic aberration by correcting certain wavelengths of light for sharp, clear images with well defined colors.

SAL-100M28 100mm f/2.8 Macro Lens

The versatile SAL-100M28 macro-focus lens covers a wide range of photographic applications, from close-up nature subjects to midrange telephoto shots-making it ideal to carry on location or in the field. Mounted on your Sony (alpha) DSLR-A100 camera, it provides a 150mm focal length (35mm equivalent). And its superb sharpness and clarity give you professional results in every shooting situation.

Sharp Macro Focusing
You can get closer to your subject to capture low-angle shots of insects, flowers and other natural wonders — and broad depth of field lets you keep backgrounds in focus too.

Bright f2.8 Aperture
In conjunction with the Super SteadyShot? image stabilization system of the Sony a (alpha) DSLR-A100 camera, this lens captures bright, steady images even working with hand-held camera in low light.

High Contrast and Resolution
