The Sigma 105mm f/2.8 EX DG OS HSM Macro Lens for Maxxum and Sony DSLR Cameras offers advanced performance of close-up photography. The OS (Optical Stabilizer) system enables handheld close-up photography. A Special Low Dispersion (SLD) lens and one high refractive index SLD lens provide excellent correction for all types of aberration and distortion. A floating focusing system moves two different lens groups in the optical path to different positions. This system compensates for astigmatic aberration and spherical aberration and provides extremely high optical performance from infinity to 1:1 Macro.
The Super Multi-Layer Coating reduces flare and ghosting, providing high contrast images. It is also possible to use this lens with Sigma's APO TELE CONVERTERS. The HSM (Hyper Sonic Motor) ensures quiet and high speed autofocus as well as full-time manual focus capability. This lens features a splash proof design for use in harsh conditions and a rounded 9 blade diaphragm creating an attractive blur to the out of focus areas of the image.
I did considerable research on the best macro lens to suit my needs & I am NOT disappointed in my choice! To me, the only differences in this lens & the Nikon version are the weight and price!
Image quality is good. Bokeh is good - not great, but then neither is the Nikon 105. Chromatic aberration is non-existent. Autofocus is slow, though. Slower than the Nikon 105, and much slower than a pro Nikon lens. Though this is not surprising for a macro lens. It does seem to be pretty accurate, though. In any case, for 1:1 macro AF is of little importance anyway. But, the manual focus ring is not very good. Which is to say it's like the focus ring on most modern lenses, but that's not good enough for macro work. It has way too little travel - about a third of a rotation - which makes fine adjustments at close distance basically impossible. It also has a slight but noticeable slop - that small initial rotation of the ring before it actually starts adjusting focus. I *feel* like the Nikon is better, but only very slightly. The VR ("OS") works only okay at large distances, but is pretty useless by minimum focusing distance. This is also not unusual for macro lenses, but I feel like it's again a bit worse than the Nikon 105. Note also that, as with all macro lenses, the effective maximum aperture reduces as the subject distance changes. F/2.8 is only achievable at distances or at least ten or twelve feet, or more. It pretty quickly drops, reaching f/5.6 a bit before minimum subject distance. I don't know how this compares with the competitors - it's possible they vary slightly as to exactly when they loose aperture - but it's important to consider when you look at objective measurements of resolution, in which this Sigma usually shows as a bit soft wide open. At 1:1 distances, that means at f/5.6. To get optimal resolution, you need to stop down to f/8, whereas perhaps other competitors would do better closer to wide open. But of course that assumes you can handle the very shallow depth of field anyway - which is rarely the case, for me. In fact one of the main reasons I choose this Sigma over the Nikon is because this Sigma tests as a bit sharper at f/8 and below, which is basically the only range I use for actual macro. And for portraits or similar, where f/2.8 is useful, it's plenty sharp in my opinion. In summary, it's very similar to the Nikon 105, but at a significantly lower price. Not to say it doesn't have its specific advantages, but the better overall value is one of the main reasons I ultimately kept it and let the Nikon go.
I purchased this lens to shoot wedding rings with great detail. It will certainly do the job. The image stabilization will keep from from bring a tripod. I am very pleased with this lens and consider a good lens for the price (under $700).
First, thanks to Adorama for the excellent and fast service to replace the defective lens. The replacement lens arrived as scheduled. The lens is heavy. It produces sharp images if it get at the correct focus as the autofocus was some kind like hunting. Most of the time it happened at close distance with small object and no contrast colour with the surrounding area. Also in a low light environment. So, manual focus will help this out-of focus dilemma. Using tripod is highly recommended for Macro photography. Colour rendering is up to my expectation for the class of the lens' price I paid. Object blurr is good.

I am rating this at 4 stars since I have no experience with other macro lenses and so far I am satisfied with it's performance. This is my first macro lens and I decided to purchase this over the Nikkor lens solely on price. I have included several photos using this lens attached to this review. Being new to the "macro world" I see what I've been missing and now I'm already thinking about buying a macro slide (The DOF is very thin !). This lens will serve me well.
This is a nice lens that is capable of producing very sharp images. Generally I am very pleased with it, but the only thing that is somewhat annoying is the fact that it often will hunt through the full focusing range when being used for macro work. The solution is to set the focus range switch to the near range setting. This gives mixed results though as sometimes it fails to find the correct focus position. I would say that half the time I end up manually focusing when working at or around the closest focusing distance. I suspect that this is due to the shallow depth of field in those conditions. I use the lens on a Nikon D80.
I gave this one a try after seeing Sigma really changing its lineup and making some stellar lenses.. Perhaps the one I got was a dud, but I didn't want to send it back for another copy so I went with the Nikon. This one is good, but the images don't pop like those from shooting with the Nikon, and the focus doesn't seem as accurate. Comes with extras and a lower price than the Nikon, so worth a try for you to see for yourself.
I LOVE this lens. That being said, it is my first macro lens. I did plenty of research before purchasing this lens and I'm very glad I went with this one. The bokeh is a dream. I don't mind the slow auto-focus in low light because I'm more of a manual focus-er anyway. I use this lens for macro nature photography as well as portraiture. I have also found it to get brilliant results with distant landscapes. For instance, making a photograph of the Rocky Mountains from a view within Denver is such a different experience using this lens. Additionally, I bought the lens as a used item, which was $75 off the regular price (it was only lightly used.) Overall I'm so pleased and inspired by this purchase.
I am an amature photographer and recently became interested in trying my hand at Macro photography. I was a little wary because I have been told that this is one of the more difficult types of photography to do. This lens makes it much easier than I expected. It is easy to manually focus and produces tack sharp images. The lens is a bit heavy and it had a hefty price tag (even on sale) but I am convinced that the quality of the lens has made all the difference and it encourages me that, yes, even I can take good macro photos ....with this lens.
