Editorial Review

The Sigma 105mm F2.8 EX macro lens gives you superb, distortion-free images across the entire focal range, from infinity telephoto to 1:1 (life-size) macro. You can get as close as 12.3 inches to your subject--without accessories--making this an ideal lens for shooting nature photography. The "focus free" mechanical design lets the lens focus automatically without any interference from the manual focus ring, making it easier to hold the lens without affecting the speed or other normal operations of the autofocus feature. The nonrotating front lens group makes it easy to work with polarizing filters. This model is dedicated to Canon AF SLR cameras. ... Read more

Lots of fun and high quality
This is a fun and good quality lens, offering true 1:1 macro at a reasonably price.I will echo the other reviewers comments about the clutch mechanism.Pretty clunky for an EX series lens.Fast auto focusing should you wish to use it for portraiture or the like, I think it better to focus manually for macro work.I also like that this lens has a very small minimum aperature for increasing the al important depth of field in macro work. I recommend a buy here.

Essential Buy !
This 105mm Sigma macro lens with a fast f/2.8 aperture satisfies you in every department. First of all it gives you a 1:1 true life size macro and these macro images comes out truly amazing... extremely sharp, good color saturation and contrast(on Pentax ZX-7). The 105mm focal length is also suitable for taking portraits. Portrait results have also come out extremely well. The EX finish is aesthetically pleasing, scratch proof and has a metal alloy body for sturdiness. The hood which is provided along with the lens matches well with it. One can also use a 77mm dia lens cap which fits perfectly on the hood, so that the hood can remain permanently on the lens (hood is threaded so that it can screw on the lens like filters.) Excellent Lens
I bought this lens when they had a sale.It was [price] without shipping charge, and I think the price was the lowest anywhere.Read more

Great lens for the price!!!
This is an excellent lens.Note:I own the one with Minolta mount but I would imagine the ones made for Canon or Nikon differ only in mount.I was really skeptical at first because it's so much cheaper than the ones made by original manufacturer but I decided to give it a try since it's not all that expensive, relatively speaking.My lens arrived.The thing comes neatly packed with a big lens hood and a multilingual manual.The lens itself feels sturdy and well made.Very solid.To my surprise, it is made in Japan.Not that it matters all that much in this day and age but I thought anything made in Japan would've cost a lot more than what I paid for this.

Editorial Review

Sigma combined a five-lens group zoom system with an aspherical lens element when they designed the 170-500mm f5-f6.3 APO aspherical lens. This combination gives your images sharp high-contrast images throughout the entire zoom range. Its unique apochromatic lens design and three SLD glass elements help eliminate the vibrations usually found in ultra-telephoto lenses. Since the front lens group doesn't rotate, polarized filters are extremely easy to use. This lens also has a built-in rotary tripod mount to help keep the lens steady, reducing vibration during shutter release and keeping your images sharp and clear. This model is dedicated to Canon AF SLR cameras. ... Read more

problems with lens
For the money u really can not complain. But I use pro lens like the L series and they make it look silly to be honest. First is it isnt an internal zoom which introduces technical problems, while shooting etc. And the lens slides down when held on the camera unsupported, i am hoping this can be fixed because it is impossible to walk around with if it keeps sliding out. next thing is the noise. If you dont use canon lens then it is normal but i got so use to the absolute silence of focusing. You better not plan to do any sensitive wild life with this. But for the price and the 500 zoom (why i got it) its cool. My 70-210 canon is perfect but on some occasions you need that 500 and no way would i go and pay for even a 300 canon zoom so.. plus when u stick this daddy on your camera you look well pro, ull have no probs convincing the sisters that you are for real lol.

One of the best on the market. Even using a 2x adapter to get 1000mm. It is big and not too heavy and has a tripod collar ring for added stability.

Good lens but a few problems
Received lens as a gift, was thinking of buying myself. Was impressed with the looks of this monster,looks very expensive to unfamiliar folks. I use this lens on my Canon Elan 7e and from the start had a problem that I wasnt informed of when bought by friend. Problem was that certain Sigma lenses don't work properly with the new Canon camera. After some research, i found I had to ship my lens to New York Sigma factory for a free upgrade, A+. received lens in a few weeks and problem was solved. Other problem was the tripod collar is in bad spot for use with some Bogan tripod heads. the head must be used sidewards to be used with the lens. Not a big problem but a problem. Next problem is that when carrying camera with lens attached and pointing downward, the lens slides to the fully extended position and could get damaged by banging into things when not noticed right away. Other than that I like the lens. Its definitely not a pro lens but it will serve the advanced amateur well. ... Read more

Editorial Review

The Sigma 17-35mm f2.8 EX aspherical HSM lens combines a fast f2.8-f4 maximum aperture with an ultra-wide-angle zoom of 17-35mm. Also, by incorporating aspherical lens elements in the front and rear lens groups, it corrects spherical aberration that could distort your images. The internal focusing system prevents the deterioration of optical quality when you are at a close distance to your subject, and it eliminates the rotation of the front barrel during focusing. The AF drive comes equipped with a silent, responsive hypersonic motor that lets you photograph your subjects without disturbing them. This lets you capture amazing wildlife shots without the noise of an ordinary AF lens. The lens materials used in this lens are lead-free and arsenic-free ecological glass. This model is dedicated to Nikon AF SLR cameras. ... Read more

You'll never buy anything but a Sigma HSM lens again!
This is was my thrid Sigma EX HSM lens.While I've had other Sigma lens I purchased them mostly for the price.The quality was OK/acceptable.But these EX HSM (Hyper Sonic Motor) lens are the finest quality lens I've ever put my hands on!They are mostly metal vs mostly plastic.They are smooth as silk and extremely FAST focus.They seem not to seach back and forth as much for the focal point--they lock on almost immediately.This lens makes brilliant true color shots and works great with my Nikon D100.With the digital camera 1.4x factor this lens is like having a 24-50 on a film camera.While with telephoto lens this is like getting extra lens for free--with wide angles you loose a bit.But that is the camera's fault not the lens. The lens comes with a beautiful case and a high-tech lens shade.You'll never buy anything but a Sigma HSM lens again.Too bad they don't make the HSM for all their models. ... Read more
