Amazon.com Product Description
Optimized for Canon digital SLR cameras but also compatible with film SLR cameras, the Sigma 105mm f/2.8 medium telephoto lens allows a greater working distance between the lens and the subject, helping it excel in all shooting ranges. The increased working distance of the lens is ideal when taking the picture of a flower among several branches, or an insect on a leaf. The narrow angle of view helps simplify the background, while the shallow depth of field makes it easier to handle the composition. The lens also offers a super multi coating that reduces the flare and ghosting that tends to occur when using digital SLR cameras, helping create crisper, sharper photos. And thanks to the Dual Focus (DF) system, the lens is easy to hold during autofocusing, but also offers smooth and positive action should you choose to focus manually on images. Other features include a minimum aperture of f/45, a screw-in lens hood that supports the use of circular polarizing filters, and a minimum focusing distance of 12.3 inches. Offering a 35mm equivalent field of view of 178mm on a digital SLR camera, the lens carries a one-year warranty. Specifications

 I Love this Lens!!! The colors are fantastic! May 19, 2010

I recently bought this lens for a Nikon D90 camera. I am new to Macro Photography and chose this lens over the Nikon 85mm. At first I had trouble taking macro pictures with the lens. I know you are supposed to use a tripod, but right now that's just not my style. Finding a way to put a tripod in front of a flower and trying to catch the bee in the act just doesn't appeal to me. My pictures at first were blurry. My shutter speed was too low to hand hold the shots. After giving the shutter more speed I solved that problem. Now my pictures are just as nice and clear. The lens works well with my Nikon D90. It doesn't make any noise at all and is very snappy to lock in when I use auto focus. It doesn't hunt at all. I did find that in taking pictures of things close up it is easier to take the pictures in manual focus. Focusing in manual is real easy with this lens. The picture quality is fabulous! I just love this lens!!!!! I posted a link to some of my pictures in the comments section.

I'm sure this is a great lens but it was absolutely worthless for what I wanted to use it for. The focal point is soooo small and even with a good tripod you still get a good amount of camera shake or blur in the picture. I know a macro lens is often talked about when taking pictures of bugs and what not but I am a fossil dealer and was hoping to take crips pictures of specific areas on a fossil (ie. a potential undisclosed repair or restoration) but you have to be very far away and your subject has to be very very very small (ie. an ant) for this lens to be useful. If you want to take a picture of the eyeball of a wasp from far away....then yes, this might be the lens for you. If for instance your a coin collector and you want to take a crips shot of a 1821 penny....its not going to happen with this lens. You would need to place the penny on the driveway and you and your camera, with the tripod, would need to get on the roof of your house, and even then....you'd have a very difficult time getting this thing to focus on the entire shot.
I read lots of reviews that talked about how great this lens is before shelling out the cash...and I am sure it is...but you have to be buying it for its sole intented purpose (taking pictures from far away of bugs) and don't go outside that purpose expecting it to work. Am I a professional photographer and a camera and lens expert? No, but I do take approx. 10,000 pictures per week x 10 years and you begin to pick up on things just with experience.
This is a review based on how the lens performed for my intented purposes. I am not giving the lens a 2 rating...just my experience with it. Hope this helps others who were perhaps hoping to use this lens for something besides taking pictures of bugs and small flowers. Kind regards, Garry

Excellent Macro Choice March 10, 2010

This is a great lens. I see quite a few people giving it bad marks for the auto-focus system, I do not use auto focus in macro; I find it cumbersome when shooting macro.
Pros:
*Sharp, very sharp
*Acceptable low to mid lighting performance
*1:1 and 105mm are a great combination
*Build quality is very good
Cons:
*Auto-focus tends to hunt
 Good lens January 25, 2010

Salvo por que el autofoco no funciona con la Nikon D60, es una maravilla, muy luminoso y liviano.
La limitación del autofoco no es problema para macro, ya que usualmente se debe utilizar foco selectivo.
Muy buen lente para retrato por su caracter de 105mm
