Product Description

The large angle of view (122 degrees super wide angle of view at 12mm along the diagonal axis) is ideal for shootings indoor as well as landscape photography. It has a variable angle of view from 122 degrees at 84.1 degrees. Four Special Low Dispersion (SLD) glass elements are provided for effective compensation of color aberration, which is a common problem with super-wide angle lenses. Two pieces of Glass Mold and one-piece hybrid aspherical lenses offer excellent correction for distortion as well as all types of aberration. By effective arrangement of lens elements and advanced technology this lens has Super Compact dimensions of 3.9 inches full-length, and 3.4 inches maximum diameter. It is equipped with Inner focusing system that will keep the length of the lens unchanged while controlling aberration. The models, which are equipped with HSM (Hyper Sonic Motor, available for Sigma, Canon and Nikon camera mount lens) system offer Full Time Manual Focusing. It has a minimum focusing distance of 11 inches (28cm) at all focal lengths. This lens is equipped with an integral Petal-type hood to block out extraneous

Professional 12-24 lens

Review Date: January 22, 2006

Reviewer: Stopdown, Boston MA

I use this lens primarily for architectural work. It's rugged, fast focusing, and most important, distortion free (i.e., straight lines stay straight). Dramatic design, built for full frame use if (when) you decide it's time to go that way. It's also performed extremely well for landscapes....even some shots at weddings. My most frequently used lens. (Hint: on the APS-C format digital SLRS, you can leave the accessory ring on the lens - it provides additional flare resistance, and there is no vignetting.)

Excellent ultrawide

Review Date: May 8, 2007

The Sigma 12-24 is an excellent ultrawide. It is very sharp with very little barrel or pincushion distortion. It is a true 12-24 fullframe with a film SLR (love it with my Nikon N80) or full frame digital slr, and effectively an 18-36 with an APS-sized sensor digital SLR. Excelleent ultrawide for architecture, landscapes etc. At 12mm though, it is so wide that you must be careful of distortion introduced by shooting off-level. This is not to say this particular lens is faulty and distorts, but would be true of any ultrawide lens with this wide degree of coverage. While I have heard much talk of supposed poor Sigma quality control, I have no qualms at all about this lens - It is sturdy, tough, smooth and has performed flawlessly for me for years.

Impressive performance and value.

I bought this lens to service a new client that does virtual tours for hotels and resorts. Their lens requirements are 18mm for full frame digital cameras and 12mm for DX chip cameras, to shoot 360 degree VRs. I didn't want to invest the 1000.00 plus dollars for another Canon lens and Canon or anyone else for that matter doesn't make a lens with this range. The Sigma would allow me to use both my 1Ds Mk II and 20D to service this client and cost me half what anything Canon provides.

Having bought the lens mainly for Internet content, I wasn't going to be too critical about image quality from it, but I've been very surpised and pleased by it's performance. This lens has the least amount of barrel distortion of any wide angle zoom lens I've ever used. Even less than some primary lenses. To the point where it is essentally undetectable to the naked eye. It has less barrel distortion than my 1000.00+ 24-70mm f2.8L Canon lens! Operation is smooth, fast and constructions is first rate. I haven't done any critical sharpness comparisons yet, but I haven't noticed any problems from the images I've taken so far.

The lens has a very bulbous front element, so conventional filters and lens caps won't fit. But Sigma cleverly includes a high quality adapter ring with filter threads in one end that slides over the built in lens shade on the lens. A lens cap is also included that fits on the end of the ring to protect the front element while being stored. The ring vignettes at 12mm on a full frame camera, but does not on DX chip cameras. So on those cameras, conventional thread on filters can be used with by screwing them on to the end of the adapter ring. You could do also this on full frame cameras, at longer focal lengths. A gelatin filter holder is provided on the back of the lens, but I can only imagine this being useful with film cameras.

Overall, I'm very impressed and satisfied with this lens. I highly recommend it.

widest zoom on the market for a full frame

as i researched for this lens i saw people comparing this lens to the tokina 12-24 f/4 or even the tokina 11-16 f/2.8 and sigma 10-20. people say those lenses are half the price with wider f/stops. people should realize that all other wide angle lenses are dx they are not full frame. this is the widest full frame zoom there is (as of date) it is wider than the beast 14-24 f/2.8 nikon by only 2mm s but at those angles even 2mm s matter.

if you ask me which i would prefer the nikon 14-24 or sigma 12-24 of course the nikon no question but the nikon is more than twice the price and even though people call it the sharpest wide angle there is i do not know if the difference would be worth the price. f/2.8 is nice to have but this wide it does not make too much of a difference. most of my shots with this lens are night photography or landscape and for both it is better to use a small aperture. mostly i go down to f/32.

this lens is extremely sharp and on my d700 it focuses really fast. and i am talking about night time so literally no light i shine a flash light to where i wanna focus and bam it is focused. i have taken a night photography class everyone including the instructor was shocked how wide this thing is and how sharp the pictures are.

i consider myself a tough grader but this lens earned the 5 stars. yes it glares but look at the pictures of the lens there is a half a sphere on the front end of this thing how wouldn't it glare.

i put 2 pictures of the lens and 14 of some of the night pictures i have taken with it on amazon. [...]

Good Super Wide for Price

Review Date: January 13, 2008

Reviewer: Kevin B. Macy,

I bought this lens because the Nikkor version was simply overpriced. I usually do not like Sigma products but I needed a super-wide angle lens and my choices were limited for my budget.

I thought I would be settling for something less, but WOW! Actually the lens produces good images for interior architecture work. There is some color fringing but you have to magnify extremely close to see it. The aberration is what you would expect from a lens of this type. All of the above are easily corrected in Photoshop.

Pro's : Sharp images, good color and quiet Auto-focus. Minimal aberrations for the money.

Con's: Front element is a "popeye" which is not favorable for filters
