Full frame sized imageLenses that create APS-C sized image are designed for digital only. They cannot be used on cameras that have image sensor larger than the APS-C format. These lenses are not suitable for film cameras either. No Ultrasonic AFLenses with ultrasonic focusing mechanism tend to be quiter and faster than traditionally focusing lenses. Not stabilizedImage stabilization helps to reduce blur caused by hand shake, especially at high focal length or in low light situations. Image stabilization can give 1 to 3 stop advantage over none stabilized lens, based on the reciprocal rule. |

A compact macro-focus lens that covers the full range from life-size to infinity. "Life size" macro imaging means that the image you capture is the same size as the subject in reality -- giving you spectacularly sharp photos of insects, flowers, gemstones, postage stamps and other small nature subjects and collectibles. Mounted on the Sony® α (alpha) DSLR-A100 camera, this lens provides a 75mm focal length (35mm equivalent) -- which means it can also be used as a standard and midrange telephoto lens.

Rather than "reviewing" this lens, I will instead point out features which I feel will be important to a potential buyer.
* Lens made in Japan - not Chinese junk.
* Razor sharp images.
* Very crisp and bright for an F2.8 lens - it "feels" like an F1.4 lens.
* Absolutely no vignetting in the corners - full coverage.
* Focus range limiter - either infinity to close, or close to macro. Can be turned on or off. The focus range limiter is a very important feature - it prevents the camera from needlessly swinging the lens all the way from infinity to macro when it re-focuses.
* Uses 55 mm filter rings.
* Macro focus works a LOT closer than advertised. You can photograph a flea on a fly if you want.
* On-lens focus hold button - temporarily turns off auto focus if you need to. This is very useful for getting the *exact* spot in focus that you want (especially in macro mode).
* The Focus Hold button can be programmed in the camera to do focus hold OR depth of field preview.
* Iris leaves are nice and symmetrical - another sign of quality.
* Iris has 7 leafs - and they are slightly curved so that the aperture is almost a perfect circle at any F-stop.
* Lens is smooth and tight - nothing rattles like "cheap" lenses do.
If you buy this lens, you will not be disappointed.

This is, like other Sony products, very high quality. I've enjoyed a lot with this purchase.

If you want to shoot macros, you have to buy this lens. I used it with A700 and got very sharp images that I cannot get using other lenses.

Sony 50mm f/2.8 Macro Lens for Sony Alpha Digital SLR Camera
This little lens is BIG on performance. I took a photo of a blue vase my son brought back from Korea and the blues are rich, deep and very sharp. Sony makes quality lenses and this one is no exception!
