Based on the previous Minolta 100mm macro lens, the Sony 100mm f/2.8 Macro is one of two current Sony macro options, the other being the shorter 50mm f/2.8 lens. It's compatible with both full-frame DSLRs and Sony's extensive range of APS-C Alpha models, on the latter giving an effective focal...

The Sony 100mm f/2.8 macro is able to produce very sharp results combined with a negligible amount of distortions, vignetting and lateral CAs. However, longitudinal (axial) chromatic aberrations can be quite a problem in out-focus areas (f/2.8-f/5.6) resulting in a magenta to greenish tint in some...

This is a lens that only Sony could deliver. I waited to purchase this lens, ordering a competitors lens first because it was advertised as being great, but only a Sony lens is as sharp. I shoot with a Sony a99. So the A mount is great. Again, I am blown away by the quality of the photograph.

Motor is a little loud when moving. Seems to hesitate sometimes. It does take very good pictures.

I absolutely love this lens!!! It's a perfect addition to my collection. I have been taking photos of flowers for a long time, but I never had a decent macro lens that would allow me to get those extra details. This lens produces some high quality images.

Good lens. 100mm allows not to be extremely close to the object.

So far I love it. Have only been able to play with it for a few minutes. Can't wait to have more time and really explore all that it can do

It is the only lens you will need to cover all your nside needs.It is compact, fast and silent, so you can take it with you in a small pounch, no need to carry other lens.You may use it in automatic mode for great portrait and manual for special effect with shades and shadows.

I wanted a macro lens for taking pictures of insects on my Sony Alpha A58 Translucent Mirror Interchangeable Lens Camera with 18-55mm Lens (20MP) without having to get too close. I knew it would not produce the fantastically sharp pictures that the professionals get with their £1000+ lenses, but to...

Nice lens, good contrast , but quite a bit of focus hunting in my lens! Light weight lens and feels cheep but I am very satisfied results with the resulting images.
