Product Description
A medium telephoto macro lens which is designed for traditional and digital SLR cameras, its lens power layout produces an excellent optical performance. The lens coating cuts down ghost. The DG lens is designed to reduce the influence of harmful light caused by reflections from the digital image sensor. Its outstanding optical performance provides the ultimate correction against lateral chromatic aberration and distortion. This lens boasts compact dimensions of 2.9" (maximum diameter) and 3.7" (overall length). It has a filter size of 58mm and, at just 15.8 OZ, is also extremely lightweight. The minimum focusing distance of 31.2cm (12.2in) is capable of macro photography with a maximum magnification of 1:1. It is possible to enjoy photography from life-size close-up to infinity. . This lens is equipped with a "Focus Limiter Switch" that limits the AF range so improving the speed and accuracy of auto focus. It also incorporates a Dual Focus (DF) system that is designed to make the lens easy to hold during auto focusing. The large focus ring offers smooth and positive action whilst focusing manually. A screw-in hood is included, for convenient use of circular polarizing filters. This telephoto macro lens has an equivalent field of view of 178mm on a digital SLR camera (when used with the SD10).

I've been using this lens for about 3 months now on a Canon EOS-350D and the Canon 5D. It has supurb optics. At f2.8, it is sharp. From f3.0 it takes off and stays sharp up to about f14. The focus mechanism is a little different from most other lenses, but actually I've grown to like it. With a push-pull lock at the end of the lens for manual-auto focus, you can put this thing in manual mode two different ways. If you're focusing in, pull the mechanism and you don't have to worry about the camera trying to change focus and you don't have to take your hand off the lens to find the manual button. Really cool actually, just a little different at first. It is light enough that weight has never been an issue, though it does extend out pretty far when focusing. Focus speed is not as fast and there is a little more motor noise, but this too is never an issue as all my close work is manual focus. As a telephoto, it works very well, but the autofocus speed comes into play here. It will hunt in some conditions as a telephoto, but it is pretty accurate.
Save some money and take great SHARP shots with this lens. Highly recommended!
I am absolutely loving this lens! April 27, 2008

Originally I didn't want to stray from Nikon products, but Sigma definitely has my attention. This is an excellent lens in both build quality and function. It works flawlessly on my Nikon D40, metering perfectly and in addition, even though it's manual focus on my camera, it is spot on with the auto-focus indicator light (lower left corner of view finder). I highly recommend this lens to anyone who is looking to get into macro! Don't be scared if you're a Nikon D40 user, I was at first, and now I'm hooked on this lens! Do yourself a favor and buy one!

Of all my Four-Thirds compatible lenses this has become a favorite. The Sigma is sharp, reasonably compact and features an actual manual focus mode. Yes, the 50-200mm Zuiko covers this range and is just as sharp, but this lens is much smaller and lighter than the Olympus lens and is, of course, a macro lens that focuses much closer than the Zuiko 50-200mm.
Despite being optimized for macro photography, this lens works quite well for general photography and has a bokeh that is a bit more pleasing than many of the admirably sharp Zuiko lenses. In macro operation the lens often gives a greater distance from the subject than the Zuiko 50mm macro lens does, but this lens is not (as far as I can tell) able to mount the Olympus ring flash for macro work so I use it strictly for outdoors and ambient light macro work (Edit: I have since purchased the Olympus twin flash and it works very well with this lens via an easily obtained step ring adapter.)
The build quality of the lens is not up to the level of the better Zuiko lenses and it is not a weather sealed lens but it is certainly of a higher quality than the Olympus kit lenses that normally ship with cameras like the E-410/510. It's also a higher quality lens than the inexpensive Sigma zoom lenses that have been available for Olympus and other Four-Thirds applications for some time now. I would say that it has a nice feel to it both in heft and in operation.
Due to optical designs that I do not pretend to understand the front element of this lens is remarkably deeply recessed into the lens housing. In fact, it's so deeply recessed that I don't feel the need to use the supplied screw on sun shade (which is a poor design in my opinion) nor do I feel the need to use a clear filter in order to protect the front element (it would be difficult to bang it on anything given how far from the front of the lens it is). One might view this as a money saver as well as a convenience but that's a very subjective opinion I do admit.
Finally, the lens features a fully manual focus mode that works very well but unlike the 'fly by wire' Olympus lenses that many are familiar with this lens requires that you throw a switch on the side of the lens housing in order to disengage the auto-focus motors. This is not terribly convenient, however with practice one certainly can train themselves to operate the switch without taking one's eye from the viewfinder.
To sum it up, I did not expect great things from this lens given that some of the Sigma lenses in the Four-Thirds mount have been a disappointment but I was pleasantly surprised by this lens. It is sharp at maximum aperture, it is moderately priced, it is an excellent macro lens, and it is a fine medium telephoto lens on top of it all. I can highly recommend this lens as a handy addition to any Four-Thirds DSLR camera kit provided weather & dust sealing is not required.

I debated between this and the 105 Nikkor but at $ 350 versus $750, I decided to try the Sigma and return it if it was not satisfactory. The build seems good with a very solid feel and, while the autofucus is a bit slower than the AF-s Nikkors, it is fine for all but the macro shots which need manual focus anyway. Comparing sharpness at f8, it is about as sharp as my 18-135 at the center and much, much sharper as you move from the center. Overall, I'm very happy I saved the $450.
super sharp, a great value compared to other brands December 16, 2006

I previously owned the sigma 150 macro. It was super sharp and awesome in any way, just kind of big and heavy. So I decided to get the 105mm because it's cheaper and lighter, more likely to stay in my bag. The 105 lacks HSM but that's not really a problem for macro where you use manual focus, or for portraits where you don't need fast focusing. The min focus distance is about the same.
I didn't get the 60-70mm macros because I also want to use the lens for portraits and 105 is better.
I researched the tokina & tamron equivalents but I choose sigma cause it was cheaper. The reviews say they're all about the same. I agree the Tamron 90 macro is better but it's a lot more expensive. Plus I think 105 is better for portraits.
Overall I highly recommend this lens for nikons. For canon bodies, the sigmas typically front focus and I would only buy canon lenses (canon has a good 100mm macro).
