Sigma 12-24mm f/4.0 overview

  • 1Description

Sigma's third generation 12-24mm f/4 DG HSM Art Lens, available here with a Canon EF mount, refines their ultra-wide arena and delivers an image with little distortion and with a high resolution for crisp photos with a modern full-frame digital image sensor. A member of Sigma's Art series, it boasts high image quality which is helped out by the use of FLD and aspherical elements, including an 80mm large-diameter molded glasses aspherical lens, that minimizes aberrations and distortion. Furthermore, it uses a Super Multi-Layer coating that minimizes flare and ghosting.

Benefitting handling, the 12-24mm is equipped with a Hyper Sonic AF motor with an optimized algorithm for speed and accuracy. The lens also offers a large focusing ring with full-time manual override settings for quickly making adjustments. A rounded 9-blade diaphragm improves image quality by helping create smooth bokeh while the lens is constructed from a lightweight and durable thermally-stable composite. Also, the 12-24mm has a brass bayonet lens mount and is dust- and splash-proof. And, it is fully compatible with Sigma's USB Dock.

As part of the Art line within Sigma's Global Vision series, this lens' is designed to achieve truly notable optical performance and is ideally suited for creative and artistic applications.
This wide-angle 12-24mm f/4 zoom lens is designed for full-frame format Canon EF-mount cameras, and can also be used with APS-C models where it will provide a 19.2-38.4mm equivalent focal length.
Constant f/4 maximum aperture provides consistent performance throughout the zoom range.
F Low Dispersion and aspherical elements, including an 80mm large-diameter molded glass aspherical element, have been incorporated within the lens design to correct for chromatic aberrations throughout the entire focusing range and help to ensure high image sharpness, clarity, and contrast regardless of focus point or aperture setting. This optical design also helps to control distortion and limit vignetting.
A Super Multi-Layer Coating has been applied to lens elements in order to minimize lens flare and ghosting and contribute to producing contrast-rich and color-neutral imagery, even in backlit conditions.
The integrated HSM (Hyper Sonic Motor) realizes quick and quiet autofocusing, which is further complemented by an optimized AF algorithm to produce smoother focusing performance. The HSM also permits full-time manual focus control simply by rotating the focus ring at any time.
Minimum focus distance of 9.4" when shooting at 24mm for getting close to your subjects.
A rounded nine-blade diaphragm helps to produce an attractive out-of-focus quality.
The lens is constructed using a Thermally Stable Composite (TSC) material, along with traditional metals, for greater precision and use in wide temperature variations.
The bayonet mount is constructed from brass for ensured accuracy and durability.
Dust- and splash-proof construction with rubber sealing to protect the mount and a water- and oil-repellent coating on the front and rear elements.
This lens is compatible with the optional Sigma USB Dock for fine-tuning different lens characteristics and updating its firmware.

    Sigma 12-24mm f/4.0 reviews

    12-24mm f/4 DG HSM Art Lens for Canon EF is rated 4.6 out of 5 by 19.
    Rated 5 out of 5 by from Just what I expected! I haven't tried the Canon 11-24 as that is a bit out of my price range so I was really hoping that Sigma would compete with a better bang for your buck offering that would still have great image quality and I think they have delivered! Beefy lens but love the constant aperture and the dock compatibility (I had to tune my 150-600 Contemporary but so far this one doesn't seem to need it). Still, always great to have the flexibility as ymmv. Focus and zoom rings work smoothly and construction seems top notch; very happy. I thought I might miss the 11mm but honestly haven't even found myself using the 12mm that much (uploaded photo was one of the few at 12mm).

    Rated 5 out of 5 by from A real upgrade from the previous model Have the Sigma 10-20mm f3.5 and really like it. Decided to give this lens a try after getting the 50mm art lens and loving that. Did side by side comparisons at 12mm, 15mm, 20mm at F4 and this new lens is slightly sharper dead center BUT 5x sharper out to the edges. Really makes the whole scene come alive compared to the previous similar lens. Don't really notice the slight difference in length vs the 10-20mm. Not crazy about the inability to have a protective UV filter on the end to protect the glass but the Canon version is the same way.

    Rated 4 out of 5 by from A great WA lens for a fraction of the price of the Canon. I use use this both for interiors and landscape photography. The 12mm fov is wonderful. Build quality, sharpness, distortion are all quite good and what I'd expect from an ART lens. When the sun is at about a 90deg angle left or right to the direction the lens is facing it produces some really ugly flare. Easily fixed by holding up a hand or hat to block it, but something to be aware of.

    Rated 4 out of 5 by from Solid Ultra-Wide Performer. As an architectural and real estate photographer, I was interested in getting an ultra wide lens to replace my Samyang 14mm. Main motivation was to move away from manual focus. My choice was the Canon 11-24mm L or the Sigma 12-24mm. If money wasn't an issue, perhaps I would have bought the Canon. Having said such, I have to admit, I've been really happy with my initial useage with the Sigma. It has minimal barrel distortion for such a wide angle lens and very sharp from corner to corner. Solid construction and heavy. I use the Sigma on my 5D Mk III and the 6D. I can't speak for the Canon EF 11-24mm, but comparing the Sigma to the Samyang, I was quite surprised how good the Samyang can keep up with the Sigma! The Samyang image colors are cooler than the Sigma's. If you must have this lens, have the funding, and need the 12 mm then I recommend it, but if you can live with a 14 mm, you'll do well with the much more affordable and very capable Samyang 14mm f/2.8. I've uploaded few raw unedited photos of Sigma at 12 mm and Samyang at 14 mm for your comparison. Both shot at f/8.

    Rated 5 out of 5 by from Before the parade passes by... I'm having great fun with this terrific lens. Consistent with the other art lenses, it excels in both light and clarity. For urban environments, details are quite sharp and noise can be tempered in post. As much as I hankered for the Canon rectilinear, I am getting great quality for much less $$

    Rated 5 out of 5 by from Huge improvement on the older generation Sigma 12-24mm zooms I have been using the generation one Sigma 12-24mm lens for wide landscapes and architectual shots for many years. The older lens was sharp in the center but soft at the edges and corners even when stopped down. The older lens was at its worst in the 12-15mm range, right where you needed it most. I am very impressed with the sharpness of the new Art version, especially at 12mm wide open. It is impressively sharp right to the edge of the frame and even deep into the corners. Not tack sharp like the center, but very very sharp for the edges of a super wide lens. If you own one of the older Sigma lenses and are thinking about upgrading, don't wait. The new lens is a huge improvement over the older versions in every respect, including build quality, and image quality. If you consider cost as a downside to the new lens, consider the Canon 11-24mm lens. The Sigma is about half that price, so perhaps the Sigma is a bargan. In the DPREVIEW review of the Sigma Art lens they said at 12 mm it is very close to the Canon in terms of sharpness and beats the Canon in terms of vignetting, chromatic aberration (CA) and distortion. The DPREVIEW review of the Sigma lens was not as good in the 16-24mm end of the range. However, the images I have taken with the lens with my 5Ds look pretty darn good, at 24mm. At that focal length, the Sigma beats my Canon 24-105mm L lens in terms of sharpness. At 12 mm The Sigma is approaching my Canon 70-200mm f/2.8 IS II lens in terms of sharpness. If you are familiar with that lens, you will know that is impressive. For my purposes, the Sigma is a winner, especially when you consider price. That is why I gave it a 5 star rating.

    Rated 4 out of 5 by from Very good UWA for full frame This is my second Sigma Art lens. The first was the 50mm 1.4, and it's been a solid lens for me. The 12-24 appears to be following in it's footsteps. The lens is solidly built, it feels sturdy and substantial. This lens is larger than you would expect. It's way larger than my 24-105 f/4 or 17-40 f/4, it's also far heavier than either of those lenses, it's actually kind of a beast. But when compared to the Canon 11-24 it's essentially the same size. The front element is large and convex, and rests inside the built in hood, there are no filter threads. The lens cap is held in place by friction and so far it's holding nicely. This lens goes very wide and you can get incredibly close. Creating good compositions can be difficult with this perspective, and keeping you and/or your shadow out of the composition can be challenging. This lens is very slightly soft wide open, and sharpens up nicely at f/5.6. The center of the frame is very sharp with the corners trailing slightly. The focus is nearly silent and very fast, it hunts occasionally but then all of my lenses do in various situations. Price wise this lens is expensive, but when cost vs performance is taken into account it's a bargain.

    Rated 4 out of 5 by from From an Architectural Photographer I do architectural photography and shoot about 20 jobs per month. Some jobs may require very large prints. Most are for the web. I've been surprised so many times that I assume every shot on every job needs to be perfect because you never know which one they might pick for a large print or crop out a small portion for their use. I've had architects win national competitions with Photos commercial restrooms! With that in mind I've read a few reviews and found some test results of the Sigma lens and have also used the lens in my workflow. My conclusion is the lens is good. I'm comparing it to a Nikkor 14-24mm. In the sigma there are waves of sharpness and waves of less sharpness whcih I would atribute to the aspherical lenses. The Nikkor not as much. This is noticable a 100% view of my files made with a Metabones Mk IV EF Canon adapter on a Sony A7R2 at 42 megs (The auto focus is just OK.). The waves of different looking details issue isn't a deal breaker and even if one of my clients would ask for a 48 print I would not be concerned. The focus distance is VERY Critical with this and needs to be verified in the view finder as with all wide lenses. On a 42 meg file you can eaisily see there is a point of focus and the depth of field is a fantasy. But that's on interior shots when you look at the image with a very critical eye much like the guy at printing press looks at the alignment of the half tones with a loupe or a fine art photographer looks at each image for best focus. Exteriors can be focused at a distance of about 30 feet and depth of field will carry the focus. I have tested this lens at f/9 down to f/16 and its decent. The colors are a bit different that the Nikkor and will take tweaking in my work flow to fix. The contrast is good and the distortion in my sample so far is much better controlled that the Nikkor. There is a slight change in distortion as you change zoom settings. The main thing I was looking for is focus shift when stopping down and zooming. So far my test and real world jobs show none. The Nikkor is unpredictable in this regard and focus must be verified after stopping down and is guaranteed to be off after zooming. The focus seems remains on point after zooming both directions on the Sigma but I really haven't tested it enough to be 100% sure but on critical images I would verify anyway. The Nikkor always looses focus after zooming. To be fair I use strictly manual focus and the Nikkor it is designed to be use in autofocus NOT manual focus. The lens is noticably larger than the Nikkor and the build quality is excellent. The zoom and focus controls are very tight and solid and the lens is heavy. How you focus and where you focus is the key to this lens. I would highly recommend this lens. Bravo Sigma! Sent from my iPad
