Summary: This is my very first Macro lens and I am currently trying to be familiar with it. But I could tell that this lens is very sharp and fascinating piece if enjoyment. The seller is committed to the customers' satisfaction and friendly. The package arrived two weeks earlier than expected delivery date. thumbs up.
Excellent macro lens for Sony Alpha bodies either FF or APS-C - brilliantly sharp, but somewhat noisy motor

Summary: This is an exceptionally sharp lens, and gives a very nice 100 mm on FF or 150 mm perspective on an APS-C sensor body like the Sony A 77/77II. In terms of image quality it's mostly a five star lens, particularly if you stop down just a little bit to F4, but I'm giving it four stars because of its hunting and noisy motor (see cons). Call me picky or just spoiled by the newer lenses, like Sony's terrific 16-50 2.8.
Summary: I've been using this on my Sony a700 and now my a900 since this lens came out. It took me from semi-pro to pro level and selling my macros on a regular basis. The only reason it's not 5-star is that it's a bit slow to focus. It takes a bit to learn the trick here. It's a bit noisy as it focuses, too. Many a butterfly has startled from the noise. It locks down at a short stop. 1:1 is clear and colors are bright. There are no vignettes.
Summary: I recently upgraded to the Sony 100mm f/2.8 macro from the Sony 30mm f/2.8 macro lens. What can I say? I love it! I use this lens coupled with my Sony A77 and the results have yet to disappoint. I will say- manual focus (for me) works a lot better than relying on the auto focus. Although the AF is relatively silent, it seems pretty slow and "focus hunts" a bit more than I'd like.
Summary: I have used this 100 mm macro lens for years on film cameras, Sony alpha 100, Nex 5, and, now on the Sony a7R. It must be attached with the A to E-mount adapter and will autofocus through the mirror; however, there is such a stack of glass that this lens does better on the level in AF mode. I recommend manual focus in steps if you have the right situation. Close it down to F/32 for finely focused closeups or open it wide to F/2.8 for portraits with creamy bokeh.
Summary: If you want to see the world you cant see with regular lenses, then this lens is for you! I love taking pictures of bugs and flowers in macro. When your friends see it they are amazed. I even got a picture of a mosquito's shadow with this thing.
Summary: I use this lens with an APS-C sensor camera which converts this lens to an effective focal length of 150mm. This allows for a comfortable distance between the subject and lens at close range at the expense of a very narrow depth of focus. The lens is sharp; however, there is noticeable diffraction distortion (loss of sharpness) at f16 and beyond. This lens is best suited for full frame cameras for which it was designed.
