You either love it or hate it. Most of the haters really either expect too much from this lens such as focusing in no light or on objects with no contrast and marginal light. The other reason there are detractors come from focus issues.This seems to be a user problem in my opinion. When you shoot at f 1.4, the area in focus can be pretty shallow. An example is at f1.4 and at a distance of 5 feet, the areas in focus is just .45 feet. If you have a DSLR with multiple focus points, you might find what you want in focus is not selected by the camera. This gives the impression of a focus issue with the lens which it is not. If you move into close focusing such as 2 feet using f1.4, the focus area becomes less than � of an inch. Even the slightest movement by you or the subject can blow the focus. Again, this is not a lens problem but a user issue. However, don't be discouraged by the...

(SF Valley, CA) - See all my reviews This review is from: Sigma 30mm f/1.4 EX DC HSM Lens for Canon Digital SLR Cameras (Camera) I've had this lens for a couple of days and have shot in a variety of situations. The image is somewhat soft at f/1.4, but sharpens quickly as you stop it down -- f/1.8 looks much sharper and f/2 is excellent.From a purely practical standpoint, you can shoot in lower light w/o external lighting, and you can run higher shutter speeds in low light for better action-stopping when shooting people or animals. I was also amazed at the incredibly small depth of field I could attain -- for example, I was able to narrow the focus down to a single stem of a plant and have every other part of the plant far out of focus. Not something I've been able to do with my Canon 17-85mm and 10-22mm zooms. It's a heavy lens but it balances well on a 20D. Autofocus seems nearly as fast as with my Canon lenses. My one complaint is that the focusing mechanism (in auto or manual) isn't as smooth or quiet as with my Canons -- it sounds a bit rough in auto, and makes a slight "barking seal"...

Simple, it cleverly exploits a hole in nikon's product lineup as a wide aperture (f/1.4) prime lens with HSM (hypersonic motor) at a price point just above nikon's older, slower 35/2 prime.Therefore nikon purists hate it with a passion, while 3rd party aficionados tend to have a more open mind. First off, if you're looking for something razor sharp at f/1.4 try zeiss or get over it. it's no fillet chef wide open, but that's not the point. the point is that you CAN use it at 1.4, which means it can shoot in light a 2.8 would be challenged by. also you can stop it down a few clicks and still be at 2.8, or shoot at f/2 or 2.2 and not be completely wide open. Second, while i'm sure there are sample variations out there, don't be put off by doomsayers on internet forums. opinions of actual users are one thing, but i dont know how people who have never used...
