Great walk around normal that will shoot 1/1 macro as well. Compact and light. Fit and finnish not as good as My other sigmas, and lens hood is junk (it screws in and does not allow the lens cap to be mounted. Suggest a protection filter as You WIIL bump the lens as it will focus a half inc away. A screw in rubber lens hood works well.

Also good for using as a standard 50mm lens.

I purchased this lens based on reviews I had seen on other web sites and I do not regret it. The lens focuses quickly in AF mode and in manual focus, it focuses as smooth as an AF lens I've used does. I use the lens to take closeup pictures of wildlife, for example to photograph scales on a lizard that are useful for identification purposes, etc. The results are very sharp with excellent color. I am very happy with this lens. Only drawback is that it needs both a filter thread adapter to get to 58mm thread so that then a 58C ringlite adapter can be added. It would be nice if for Canon mount, the lens either came with the ridge for Canon macrolites or came with a 58mm thread so that canon adapter could be used without a step-up adapter.

I keep this lens on my camera most of the time. It is good for many different types of photography. A good carry around lens. On my crop camera it gives a little telephoto boost, but not too much.

very nice macro lens. The housing is a bit weak (I dropped mine once & it needed a new focus chassis), but it's a very nice alternative to the canon 100L

Took one last chance on Sigma, never again. [...] Needless to say, I went with a Canon and guess what? It works brilliantly!

I like this lens, because it is not to big to handle while hiking, also can be used for an excellent macro lens, and as a fixed lens it does it's job very well.

...especially during the spring and summer when the bugs, flowers, trees and other things are in full swing. I took this out to shoot some insects and the like the day I got it. If you aren't familiar with the focus limiter and try to use auto-focus without it, you'll find the lens hunts and is sometimes not so accurate at acquiring the subject. That being said, this lens produces VERY sharp images, and its focusing distance is incredible. In a nutshell, great lens.

It is tack sharp which is what I was looking for. It can be very slow to focus, even on the limited setting, and it seems to get confused once in awhile. The motor is loud, too, but I did know that about this lens when I bought it. Overall, I am happy with it and would reccommend it as a great portrait and macro lens.

As a beginning macro photographer, I was stunned by the quality of the lens in doing simple photography of everyday objects in my home. This is going to be great fun!

Here's a nifty way to get professional-looking images of small-scale-subjects. Sometimes, modeling (a lighting effect caused by placing the light to the side of your subject) isn't the best way to light your shot. Here's how to get flat lighting--the opposite of modeling.

A ring light is a flash unit that has special characteristics that are optimized for specific and diverse kinds of shooting such as macro, scientific applications...and fashion photograhpy.
Optimized image quality for Digital SLR cameras. Floating Internal Focusing (FIF) system minimizes the aberration in entire focusing range. Super Multi Layer (SML) coating reduces the ghost caused by reflections from the surface of digital image sensors. Minimum aperture of F/45 provides greater depth of field A screw-in hood for convenient use of circular polarizing filters
MACRO 50mm F2.8 EX DG incorporates the very latest optical technology and is an ideal standard lens for digital SLR cameras. The new advanced lens design corrects various aberrations. This macro lens is specially coated to get the best color balance whilst cutting down ghost caused by reflections from the digital image sensor. This lens provides the utmost correction against lateral chromatic aberration which is a serious problem for digital SLR cameras.
The new MACRO 50mm F2.8 EX DG incorporates a "Floating Internal Focusing" (FIF) system which enables this lens to photograph objects precisely not only at life-size reproduction but also at infinity. The lens has a minimum focusing distance of 18.9cm (7.4 in) and is capable of true macro photography with a maximum magnification of 1:1. Experience the enjoyment of real life-size macro photography. This lens is equipped with a "Focus Limiter Switch" that limits the auto focus range, allowing the camera focus more quickly. This lens has a minimum aperture of F45 which produces a tremendous depth of field. A screw-in hood is included, for convenient use of circular polarizing filters. It is also possible to attach a 72mm filter in front of the lens hood.
