One of the best lenses for Canon I have ever used,
Verified Purchase(What's this?)
This review is from: Sigma 28mm f/1.8 EX DG Aspherical Macro Large Aperture Wide Angle Lens for Canon SLR Cameras (Electronics)
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:
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.
