About Sony 100mm F/2.8

Product Information provided by the Manufacturer

100mm F2.8 Macro Lens

This 100mm F2.8 Macro lens offers a greater working distance so you can capture tight macro shots of small-scale wildlife without scaring subjects away, and you're not so close that you need special lighting to illumniate your subject. It's also a first-class telephoto lens for normal shooting and is a good choice for portraits or other subjects that require a bit more reach.


Circular Aperture

When changing your aperture to defocus the background, the light sources appear blurred. This 'bokeh' effect of the blurred background can be enhanced with circular aperture blades used in this lens. Conventional aperture blades have flat sides creating unappealing polygonal shaped defocussed points of light. α lenses overcome this problem through a unique design that keeps the aperture almost perfectly circular from its wide-open setting to when it is closed by 2 stops. Smoother, more natural defocusing can be obtained as a result.

Focus hold button

Once you've adjusted focus to where you want it, pressing this button on the lens barrel will keep the lens locked to that focusing distance. The preview function can also be assigned to this button through the camera's custom settings.

Focus range limiter

This function allows you to set a limit on the focusing range which can save you time during AF operation as the lens will not 'hunt' through the entire focusing range. In macro lenses, this limit can be on either the near or far range (as pictured). In the SAL70200G, the limit is set on far ranges only. In the SAL300F28G, focusing can be limited either to a far range or to a range that you specify yourself.

Distance encoder

The distance encoder plays an integral part in ADI flash metering, which delivers high precision flash metering that is unaffected by the reflectance of subjects or backgrounds. The distance encoder is a lens component that directly detects the position of the focusing mechanism, and sends a signal to the CPU in order to measure distance to the subject. During flash photography, this data is very useful in calculating how much flash output is appropriate to the scene.

Shoot macro close-ups at a distance - 100mm F2.8 Macro lens (SAL100M28) 
 The 100mm focal length lets you do the seemingly impossible - take close-ups at a distance. Now you can easily capture tight macro shots of wildlife and nature. 

Get incredibly close to small subjects with the Sony SAL-100M28 macro lens. Its superb clarity gives you professional results in almost any shooting situation. The superb macro-focus lens for both close-up and distant subjects. This versatile 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 the Sony a (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. 

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

Excellent optical precision gives your shots greater visual accuracy for close analysis of your subject. Speeds auto-focus response by limiting the range of distances that are brought into focus, Close-up Range, or Telephoto Range. For full creative control, a focus hold button located on the lens can lock auto-focusing. In auto-focus mode, the manual focus ring does not rotate, which improves handling ease. 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. 

Smooth defocusing - Instead of a standard polygon-shaped lens aperture, this lens features a 9-blade circular aperture for more natural, rounded defocusing, or bokeh. 

Say goodbye to blur - Pair the lens with a Sony camera with SteadyShot INSIDE and you'll enjoy smooth, blur-free results when shooting handheld, even zoomed in. 

Refined optical performance - Multiple lens elements crafted from high-performance optical glass help minimize distortion and aberrations, giving you crisp, sharp images. 

Focus hold button - Easy-to-reach button lets you lock focus at the current setting. 

Focus range limiter - Useful when you need the fastest possible autofocus response.
