Sigma 12-24mm f/4.5-5.6 EX DG ASP HSM Reviews

SLRLensreview reviews the Sigma 12-24mm f/4.5-5.6 EX DG ASP HSM and writes;
“Sigma 12-24mm f/4.5-5.6 EX DG HSM shows pretty decent performance throughout the zoom range from f/8 and on. At wider apertures the lens exhibits some weakness around borders (primarily in the 12-17mm range), so you should be prepared to stop down to achieve the best results.”

Photozone reviews the Sigma 12-24mm f/4.5-5.6 EX DG ASP HSM and writes;
“The Sigma AF 12-24mm f/4.5-5.6 EX HSM DG proved to be a very decent performer for an ultra-wide zoom lens (on APS-C). It has specific strengths (extremely low distortions) and weaknesses (CAs, vignetting at 12mm) but generally the optical quality is very fine with good to very good resolution figures. The build quality is also very impressive.”

Photodo reviews the Sigma 12-24mm f/4.5-5.6 EX DG ASP HSM and writes;
“The one area where, with a lens of this type and extreme angle of view, that you would expect to see problems are in the area of distortion. With the wide angle of view, some noticeable distortion could well be acceptable even so. However, the lens showed no signs of this problem and even when measured it proved to be well inside acceptable limits.”

Ephotozine reviews the Sigma 12-24mm f/4.5-5.6 EX DG ASP HSM and writes;
“All of the usual anomalies, such as chromatic aberration and ghosting are well controlled throughout both the zoom range and the aperture range. Flare can be induced in any lens, especially one as wide as this one is, but the control of it is very well handled and when it does occur, it does not wreck the contrast of the whole frame.”

Sigma 12-24mm f/4.5-5.6 EX DG ASP HSM User Reviews

versatile wide-angle | Rating: ★★★★★
“For ultra wide angles I’ll use it with film (Nikon N-80) and for more conventional wide angle with my Nikon D-200. It’s one of three lenses I’m taking with me on vacation to the mountain states. The others are a Nikkor 28mm – 85mm and a Nikkor 70mm – 300mm with 2X Tamron SP doubler. Since I don’t yet have photoshop or similar I wanted to be able to take real wide shots without having to paste them together. “ – by Fredrick O. Smetana

Excellent ultrawide | Rating: ★★★★★
“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.” – by Robert A. Laubach

Good Super Wide for Price | Rating: ★★★★★
“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. Sharp images, good color and quiet Auto-focus. Minimal aberrations for the money. “ – by Kevin B. Macy

Not s bad as most people think.. | Rating: ★★★★☆
“I’ve been using this lens for about 3 years now and wanted to upgrade so I read all good things about Tokina (since I could not afford the Nikon). I purchased the 12-24mm Tokina and returned it because of horrendous camera flare which the Sigma does not have. Granted there is “some” flare issues with most wide angle lenses but the Tokina was totally unacceptable. I didn’t see any major differences in picture quality either. Both lenses must be used at F/8 for the best sharpness. I am keeping the Sigma and buying a Nikon D300 instead. “ – by Valente Riolo

Impressive performance and value. | Rating: ★★★★★
“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. “ – by Terry Doran

Amazing Lens | Rating: ★★★★★
“This lens is quite extraordinary on a full frame camera like my Canon 5DmkII. Some like to think it’s only great for landscape but I’ve had excellent results with it for portraits. Especially for fashion and really odd, but cool shots. “ – by Michael Catacutan

Fantastic glass | Rating: ★★★★★
“I got this for my Nikon D700 when looking for a wide-angle lens that wouldn’t break the bank and had a large wide angle view. Wow, was I surprised by the quality of this glass. It is the widest you can get for a full-format dSLR, and it is sharp across the entire focal range. I won’t go into a detailed review here of the the glass — you can google the reviews and the technical specs. “ – by RonAnnArbor

Pefect except for one flaw.. | Rating: ★★★★☆
“This lens is fantastic… Takes brilliant photos, no fish-eye, incredibly wide, just what I wanted. ONLY thing that seems an obvious mistake is that Sigma doesn’t have a clear way to mount a CPL (circular polarizing lens) on this baby. I’ve had to search and search for ‘workarounds’.” – by D. Bradshaw

widest zoom on the market for a full frame | Rating: ★★★★★
“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.” – by Nikonian

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.
