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 ¾ 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 above comments. This lens has so many possibilities from creative images to group portraits to low light photography. You just need to put in a little effort to learn the lens (and your DSLR). Also remember that stopped down to f4 at 10' gives you 5.45 feet in focus.
The 30mm lens also is about as close to a 50mm lens on a 35mm film SLR as there is. A 50mm lens was considered the de facto standard for an SLR in the old days and many people never had anything else. This is a very versatile lens.
The lens itself has an excellent build quality and includes extras such as a lens hood and case. It is sharp and offers great contrast and compares well against such a well regarded lens as the Canon 35mm f1.4L which is about 3 times the price.
You will not be disappointed in this lens at all and I highly recommend it. It is one of my favorite everyday lenses for my Canon 20D. (My everyday kit includs the Canon 17-40mm f4L, 70-200mm f4L, and a Canon 580ex flash.)
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" sound as you go from close to distant focus manually.
Nice of Sigma to include the lens hood and case, instead of charging exhorbitant amounts for the hood as Canon does.
Overall, this is a very useful addition to my zooms, and it will definitely allow me to get usable natural-light photos in situations where I couldn't before.
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 the lens can qualify it whatsoever.
(but if you do order this lens, make sure its from a vendor with a good return policy. check for front focus issues when you get it; if you have a problem, sigma will recalibrate the lens. saves them money in the QC department, but at least they have good customer service.)
for the record, i own three sigma lenses, all EX series, all bought online, and they all worked perfectly fine from day one.
There are two categories of folks who will be looking at this lens: d40/d40x/d60 users and everybody else.
for a d40/60 kinda person who wants to take no-flash, low light pics, there are no other options in this focal length and aperture class with an internal motor. period. you'd have to go to the micro-nikkor 60mm or 105VR to get an AF-S prime.Read more ›
After conducting numerous focusing tests on charts, my copy also has significant front focusing issues at all apertures. In real world use, the focus issues became apparent quickly. So I decided to contact Sigma.
Sigma stated that the focusing problem is not with their lenses, but rather with my Nikon D80 and other Nikon cameras. I informed them that my D80 focuses properly with 3 different Nikkor lenses, but they still denied there could be a problem. After inspecting the sample, they also were UNABLE TO FIX any problem (probably because they wouldn't acknowledge a problem existed, even with the test charts showing front focus).
Anyone who dismisses the front focusing issues as operator error ignores the fact that people who buy speciality lenses, such as the Sigma 30mm, generally are experienced photographers. Additionally, the same high number of front focus issues aren't experienced with other similar lenses, such as the Nikon 28 f/1.4. It seems like poor quality control to me.
YOU RUN THE RISK OF BUYING A LENS THAT IS USEFUL ONLY FOR MANUAL FOCUS IF YOU BUY THIS LENS, AND WHERE YOU WILL BE UNABLE TO HAVE IT REPAIRED VIA WARRANTY.
However, the lens is built from quality materials. Using manual focus, photos are sharp, although I am noticing some softness as you move from the center of the frame. Assuming the auto focus issues could be resolved through adjustment, it would have been lot of lens for $369.Read more ›

Nice lens that's near 50mm equivalent focal length on a crop frame (sub frame) sensor. Just don't buy one for a full frame. When used on my Canon 6D, the vignette is extreme.Published 4 months ago by Jason Hattery
