This fish-eye lens is designed to capture a 180-degree view in a 22mm diameter circular image. Even familiar subject matter can be given startlingly fresh creative expression through this exaggerated perspective that creates unusual distortion effects. In addition to creative expression, this lens can be used for academic or technical applications that involve solid angle measurements. An example would be capturing the angle of view through a window with a driver in a car or a pilot in the cockpit of an airplane. This lens accepts removable gelatin filters in a rear holder. The optical materials are made from lead-free and arsenic-free ecological glass. This model is dedicated to Nikon AF SLR cameras. ... Read more

My everyday lens from now on.
I bought the Sigma 28-135mm 3.8 - 5.6 to replace my broken Canon 28-70 3.5 - 4.5. The Sigma is nearly as fast, but offers a much greater range of focal lengths - the 70-135 range that was NOT on my Canon makes the lens far more versatile. Furthermore, the Sigma offers a very effective macro range (at the 135mm focal length only). Even when not in the macro mode (which requires throwing a switch) the lens focuses very close (to about 20").

Like the Sigma 70-210mm, the 28-135 has a little difficulty focusing in low light settings (more so than did my Canon 28-70). However, in good lighting conditions it focuses very quickly. Photos appear sharp from edge to edge, at all focal lengths. Zooming is smooth, and I have noticed no "creep."

The lens comes with Sigma's specially-shaped hood, designed so as not to interfere with wide-angle shots. The hood makes it very difficult to put on and take off the lens cap (so far the only negative thing I have to say about the lens).

For what it offers - a great range of focal lengths and good macro at a reasonable price - this is a fabulous lens. It gets 4 stars instead of 5 because of its 3.8 aperture - a 2.8 would be nicer, but probably far more expensive. (And yes, I'm aware of the Sigma 28-105mm 2.8-3.?, but its reviewers have questioned its sharpness).

Get this lens and it will probably stay on your camera all the time. Mine will. ... Read more

Amazon.com Product Description

Sigma's 70-300mm f4-f5.6 APO macro super lens has a compact apochromatic telezoom lens that incorporates two special low-dispersion glass elements in the front lens group with one special low-dispersion glass element in the rear lens group. The arrangement of the optics serves to minimize the chromatic aberration that can occur.

This telemacro zoom lens can achieve a magnification ratio of 1:2 (one-half life size) for macro and telephotography images at its 300mm focal length. As an accessory, you can add a 58mm achromatic close-up lens (not included), and get even closer focusing and reproduction ratios of 1:1 (life size) and still maintain excellent optical quality. The optical materials are made from lead-free and arsenic-free ecological glass. This model is dedicated to Nikon AF SLR cameras. ... Read more

Easy come, easy go.
I returned this lens the same day I received it. I found the macro function to be combersome, less than crisp, and with a miniscule depth of field. With no lock for the lens barrel, the lens extension continually slid forward with the slightest negative angle. And, once extended, the lens was awkwardly balanced and difficult to steady on my Novoflex head.

Excellent Zoom with Great Macro Capability
It was between the very resonably priced 70-300 Nikkor and this one from Sigma. I chose this one, mainly on the basis of the macro capability, and glad I did. I've gotten some super honeybee shots, and frame-filling portraits. Resolution couldn't be better, fully equal to the Nikkor or any fixed focal length lens in this range (as far as I can judge.) Light and relatively short, it's convenient to carry. Pair this with a good short zoom, and you're set. ... Read more

Amazon.com Product Description

Encompassing all popular focal lengths from the 50mm normal to 500mm ultratelephoto, the Sigma 50-500mm f4-f6.3 EX RF HSM hyperzoom lens gives you amazing versatility, plus a 10:1 zoom ratio, while its rear focus system ensures fast, convenient manual focus. The use of an apochromatic design, plus four optical elements composed of special low dispersion (SLD) glass, a seven-group zoom system, and multicoated optics combine to give you high-quality images.

This lens, featuring Sigma's silent hypersonic motor (HSM) focusing system, allows you to shoot pictures of your subject without the normal noise of an automatic focus system. In addition to its quiet, responsive AF function, you can also use the full-time manual focus at any time. The zoom lock mechanism helps reduce the "zoom creep" distortion that can occur when your lens is tilted up or down.

Sigma uses magnesium in the tripod mount to help reduce the weight of the lens (it's just over 65 ounces), yet still maintains the strength and rigidity necessary to support its weight. This model is dedicated to Canon AF SLR cameras. ... Read more

Best bang for the buck!
I just recently got into photography as a retirement hobby and was fortunate to be able to acquire a Canon D60 within two days of ordering one from Kaimuki Camera Store in Honolulu.

To complete the Canon system I purchased Canon Lenses, the EF 16-35mm f/2.8L USM, EF 28-70mm f/2.8L USM, Canon EF 75-300mm f/4.5-6 IS USM, and a Canon EF 35-350mm f/3.5-5.6L USM. I also got a Tamron 28-300mm UltraZoom XR f/3.5-6.3 LD Aspherical Macro, and my daughter got me the Sigma EX 50-500mm f/4-6.3 APO RF Zoom lens, along with the Sigma 2.0 teleconvertor lens, for my retirement party.

This Sigma 50-500 lens is like magic for me in that I've taken pictures of the city from my balcony and upon proccessing the images on my computer there are images that I didn't even know were there through my naked eye. I was amazed that I could read freeway signs that were easily over ten miles away.

Tonight my wife, daughter and I went out to shoot pictures of the full moon. We were all pleasantly surprised when we could see the details of the moon's surface, with the craters and other distinct features. By the way, I did have the Sigma 2X teleconvertor attached. If I'm not mistaken, along with the extra teleconvertor's 2X power, the magnification was also further enhanced by the inherent 1.6 mutiplier effect through the digital camera's characteristics.

All of the other reviewers are correct in their opinion of the 50-500's weight. It is heavy, and so far, I've gotten a lot of comments about the neat "retro" look with the crinkled black finish just as Bluegun opined. I also noticed that on several occassions people in front of me actually moved aside to give me room to shoot pictures at our Aloha Week events and once at a University of Hawaii sporting event. I guess the big tripod, and once, monopod monted Sigma zoom possibly gave me the look of a pro, which, of course, I'm far from.

I really like Sigma's locking feature so that the lens won't creep open when moving about. Also, when trying to manually focus the lens it is pretty tight, or sticky, as Bluegun has noted, however, I may be wrong, but I kind of like it tight rather than having it too loose. When I checked for comparisons in features/pricing this Sigma 50-500 is a definite bargain. I can't seem to find any comparable Canon lens with that range of the 50-500. The closest Canon has is not anywhere near Sigma's price points. Of course I pretty well believe that Canon's quality/price against Sigma's is definitly not comparing apples and apples. What Sigma has done, however, is help to make a big powerful lens that is affordable for just about anyone who can't affordably justify Canon's at the moment. Case in point - Sigma's 50-500 zoom has made it possible for my daughter to have the luxury of purchsing a good as well as impressive "big lens" for her daddy on her student's budget.

heavy but worth it
I got this lens to replace my 600mm reflector which is fixed aperture with a dreadfully small depth of focus. This lens is spectacular by comparison: excellent focus depth, with F4-6.3 it is light-strong enough to get away with a lot of stuff that reflector lenses don't allow as they suck so much light. I do motorsport and nature photography, so fast exposure times are key, and this lens allows for good flexibility in difficult light conditions or where you need to be super-quick without compromising depht-of-focus. I use this lens on a Canon EOS 7E elan, and this is an outstanding combo for motosport and nature shots, since both the lens and the camera are very quick and very quiet. My two only complaints with this product are the weight (very heavy, bring Advil to shooting a whole Grand Prix weekend!)and the fact that the zoom is a little slow-going, but maybe that'll easen up with more use. Overall another very solid Sigma product, unbeatable value for the money. I shut off the autofocus sometimes when I do difficult action pics where there's potential for automatic focussing errors, but if you don't, be prepared to bring extra batteries, since moving the autofocus in a big lens like this will suck the power out of your camera in no time.

Very decent lens for the money.
Heavy as lead. Slight "stickiness" in the zoom when changing directions at full extension, but nothing major, feels like it will work out. Nice finish, kind of retro, speckled, grainy finish, good gripping and looking. Good, very quiet focusing. Excellent sharpness, using it on a D30 digital, so can't really tell about aberrations at widest and longest, since I lose the edges with my CMOS anyway. FOR THE MONEY, I don't think you have a better choice. Of course, if you can afford it, get the Canon "L." Don't think you'll be disappointed for the price.

Heavy!
Its a good lens with with 500mm Zoom. It is necessary to shoot wildlife. However, the lens is EXTREMELY HEAVY! That limits its usage considerably. I went to shoot whales recently. Thanks to the fast zoom, I am the only one that got pictures of whales, everyone else I know, only got a small dark spec in the ocean! ... Read more

Bargain alternative to Canon's 1.4x Teleconverter?
The Sigma APO teleconverter is a little more than half the price of the Canon teleconverter, and it boasts an APO element to reduce chromatic aberration. I've found this teleconverter to be reasonably sharp, but there is noticeable vignetting when I use it with my Canon 300mm f4. Sigma claims that the teleconverter is designed to be matched with their high-end tlelphoto lenses, and perhaps this is the case. However, I wasn't very satisfied with the performance of this teleconverter. ... Read more
