This is my first macro lens and I love it the results are above what I imagined and I am enjoying the results, Its functions are easy and user friendly, I can only get better with this lens on my camera.
I love this lens! It hasn't come off my A100 DSLR since it arrived. I have had it about a month and shot over 3000 images learning all aspects of this superb optic. It is sharp, shockingly sharp! Until now I was using my 18-70 mm and 75-300 zooms with and without close up filters. Mostly good close up shots and occasionally a real nice sharp close up. The 100mm f2.8 is in another league. I have been in photography since 1968, and this lens once again proves my theory and gut feel that fixed focal length prime lenses are still king of Resolution. My shots of flowers and bees are the best ever. For the first time I can now see in my digital images just how messy bees are with pollen! Oh, and let's not forget the color. The color is intense in every image. Warning: This is a demanding lens. So first and foremost read the instructions on how to use the "focus limiter." This is a must. It will speed up focusing for all uses, including macro, scenes, architecture, and general photography. Also realize that this is a telephoto lens with extreme close focusing. As a result, especially for close ups, the Depth of field is extremely shallow when using f2.8 and similar f-stops. This is an optical law, not a defect, so use it to your advantage by planning shots requiring selective focus. By following these tips, taking many shots to learn about the lens, and if this is your first prime lens, you will be ushered into a new level of digital photography performance. PS: Amazon was fast and reliable in shipping my 100mm f2.8 macro.
Arrived in good order and after using it for several hours in one day I can report no problems and it functioned well. The kit lens that came with the camera was good for the Sony A350, but this lens enhances the camera's utility and effectiveness greatly.
