Summary for Sigma 105mm f/2.8 EX DG Medium Telephoto ...- Sigma Macro Lens...great buy!!
Notes on Sigma 105mm f/2.8 EX DG Medium Telephoto ...- This lens is worth the money. I found that it is a bit slow to focus in AF mode, so I use MF mode instead. It produces lovely, sharp photos in 1:1 macro, portraits, and in hyperfocus depth of field landscapes. Once the lens has focused it becomes very quick thanks to it's F/2.8. It also has a good quality feel to it, much better than the kit lenses that come with the Sony SLRs. It feels sturdy in hand with a good weight: not too heavy, but not too light.

Notes on Sigma 105mm f/2.8 EX DG Medium Telephoto ...- There are several macro lenses in the 100mm focal length variety for the Minolta/KM/Sony line. They are all good lenses and offer pretty much the same problems as well. I am particularly fond of the Sigma offering. The build quality is fabulous, this is a very very solid lens. The photos are tack sharp and colors are well-saturated and lovely. In the US, the Sigma EX line offers a four year warranty and it is the least costly of the high quality 100mm trio of lenses. Highly reccomended. Here is a link to one of my favorite flower shots form this summer (2006).
