Product Description
Manufacturer's Description
This lens has a macro focusing capability with fast F1.8 maximum aperture, which is ideal for Digital SLR cameras.This lens is capable of Macro photography, with minimum shooting distance of 20cm (7.8 inch) (reproduction ratio 1: 2.9) and angle of view is 75.4. You can take picture not only the subject but also the surrounding scenery.The lens has an advanced optical construction, in order to obtain adequate peripheral brightness with open aperture. Also, the iris diaphragm has 9 diaphragm blades to obtain beautiful out of focus images in the foreground and background.The lens incorporates a Dual-Focus (DF) mechanism. It is easy to hold the lens, since the focusing ring does not rotate during auto-focus, yet it provides adequate focusing torque of the focusing ring during manual focusing of the lens. Also, this also allows the use of a Petal-type Hood and the easy use of a polarizing filter.It incorporates a floating focus system and uses two aspherical lens elements for minimizing distortion, aberration and astigmatism.

One of the best lenses for Canon I have ever used
17 Jan 2011
Amazon Verified Purchase
From precise macro to wide-angle shots, this lens performs very, very well. The images it produces are tack-sharp. I have all but abandoned my 50mm f/1.8 on my 50D...this lens is closer to "normal" on the crop sensor. The bokeh is marvelous: creamy, smooth, and dreamy. The colors are typically Sigma: that is to say a little warm and not overly saturated but not exactly subdued. The build quality is far better than most Canon lenses in this price range, which is also typical of Sigma. The auto-focus performs well, occasionally seeking at very close macro distances, but that is normal for the small DOF of macro lenses, plus I do not have a ring- or macro-light.
As I said, I use this lens as "normal" on my crop bodies but on the 5D (I have the original not the Mark ii) it really shines as a wide angle lens. 28mm is the perfect indoor angle offering enough field of view to capture everyone in your scene but still allowing use of flash to fill the dark spots using my 580 EX II. I have essentially stopped using the 24-105 f/4L for wide angle work because this lens is so sharp.
Now, the obvious strong point of this lens is the f/1.8 aperture which is sharp, sharp, sharp even wide open with virtually no falloff and almost no CA. I never hesitate to just leave it wide and shoot in TV mode to stop action or to create action trails. Using it indoors at 400 ISO I get perfect images every time without the harshness of flash.
I have used this lens on these bodies with excellent results:
50D
5D
Rebel XTi (400D)
Elan 7 (35mm film)
Elan IIe (35mm film)
EOS 3 (35mm film)
So for crop or full frame, this is a great walk around, macro, and wide angle lens.

Great value if you do know how to use it correctly
23 Feb 2010
It's a wonderful lens! Great value for the money!
At f/1.8, it's a fast lens that's capable of shooting in low-light condition, or making artistic photos with dramatic bokeh. With 9-blade aperture diaphragm, the bokeh (or the out-of-focus blur) is so buttery and dreamy.
However, you do need to know how to control the shallow depth-of-field (DOF) with the wide aperture opening or big distortion from a wide-angle lens. If you aren't careful with the composition and have the subject too close to your lens, then the 28mm will cause the subject to have a big & round face. As for DOF, I calculated that a 28mm at f/1.8 with the subject distance of 4', is only 6". If you are not careful with the focus, then you'll get a blurry photo.
Many folks are concern about the automatic focus accuracy of this Sigma lens. When the subject is only 1.5' away (1" DOF), I did notice that I was getting a front focus of about 1". That is probably within the tolerance of the lens still, since the error was a combination of the deviation of my camera body and the lens. An easy adjustment of the calibration setting in my camera took care of the problem and everything is hitting bulls-eye after that.
The 77mm lens diameter is the same common Canon diameter of many EF lenses. Thus, all my existing filters fit just perfectly. The exterior finish is the typical wrinkle EX finish and looks nice. Although the front lens do not rotate with focusing, the lens itself does extend or contract when focusing. In addition of the automatic/manual focus switch, there is the quirky pull/push clutch system for fine focus adjustments. The communication with my Canon 1D Mk III is great. It would be nice if this lens had the Sigma's Hypersonic Motor (HSM) instead of the conventional, robot-cop sounding, motors. However, the focus was quick enough and not much hunting for focus even in darkness.

Great lens, especially for the money

I have been a fairly serious hobbyist photographer for about a year now, since purchasing my Canon DSLR. Many hours spent researching photography in general and lenses in particular have led me to this lens. From what I've found online and on Flickr, it doesn't seem to be very well-known, especially compared to this other Sigma lens, which I also considered:Sigma 30mm f/1.4 EX DC HSM Lens for Canon Digital SLR Cameras. In other words, this purchase felt more risky to me, but I think it turned out quite well.
Pros:
-Future-Proof: If you're considering this lens, you most likely have a "cropped" sensor DSLR. All but the most expensive DSLRs have them. Many new lenses - "DC" lenses for Sigma, "EF-S" lenses for Canon - will ONLY fit on cropped-frame cameras. In the future, if and when full-frame cameras become cheaper and more popular, these lenses might not fit new cameras. This "DG" lens, however, will fit on both cropped- and full-frame cameras (albeit with different focal length equivalents - it takes wider shots on full-frame).
-Depth-of-Field: I'm loving the small DOF on this lens. It's nice and smooth.
-Low-Light Photography: With its large aperture, it's fast in low light. Quite fun if you're used to slow zoom lenses!
-Construction: Looks nice, feels nice, and the focus ring has just the right amount of resistance.
Cons:
-Auto-Focus: The AF could be faster, but that is to be expected without a hypersonic/ultrasonic motor. It also sounds more gravelly than I'm used to, which is a little unnerving, but it seems fine. I have not seen any AF accuracy problems.
Other Considerations:
-Size/Weight: It's hefty, but it's nothing compared to some of those telephotos out there. Admittedly, that's an apples-and-oranges comparison, but still. I love the size and weight; your mileage may vary.
-77mm filter thread size: Again, it's big. Filters can be expensive. On the other hand, it looks and operates like serious business.
-Image Quality: I am very pleased with the quality, but I'm no studio photographer. I don't take pictures of test charts for fun.
Thumbs up!
