Sigma 20mm f/1.4 Overview

  • 1Description

Truly wide and truly fast, the Canon EF mount 20mm f/1.4 DG HSM Lens is a member of the venerable Art series of Global Vision lenses from Sigma and pairs a sophisticated optical design with a robust physical construction. Comprised of 15 elements in 11 groups, the lens design includes two "F" Low Dispersion (FLD) elements, five Special Low Dispersion (SLD) elements, and two aspherical elements to significantly reduce chromatic and spherical aberrations, as well as limit distortion for clean, sharp, and evenly illuminated imagery. A Super Multi-Layer Coating has also been applied to minimize surface reflections, flare, and ghosting for increased contrast and color accuracy. The wide focal length and consistent image quality make this lens especially suitable for landscape, interior, architectural, and astrophotography applications, while the fast f/1.4 maximum aperture deems it ideal for natural and low-light shooting.

Complementing the optical performance is an equally adept Hyper Sonic Motor, which provides fast, smooth, and near-silent autofocus performance. This focusing motor also enables full-time manual focus override at any time just by rotating the focus ring for refined manual control and focusing as close as 10.9". The lens barrel is constructed using a Thermally Stable Composite material, which supports working in a wide variety of temperatures and conditions, and the lens mount is constructed from brass for long-term durability and mounting accuracy. Additionally, this lens is also compatible with the optional Sigma USB Dock for fine-tuned control over focusing parameters and other lens characteristics.

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.
Prime wide-angle 20mm f/1.4 lens is designed for full-frame format Canon EF mount DSLRs, and can also be used with APS-C models where it will provide a 32mm equivalent focal length.
Fast f/1.4 maximum aperture is well-suited for working in low-light conditions and also provides greater control over the focus position when using shallow depth of field techniques.
Two FLD, five SLD, and two aspherical elements 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.
A rounded nine-blade diaphragm helps to produce an attractive out-of-focus quality.
Fixed petal-shaped lens hood helps to reduce lens flare when working in strong lighting conditions and also offers some protection to the front element of the lens.
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.
This lens is compatible with the optional Sigma USB Dock for fine-tuning different lens characteristics and updating its firmware.

    Sigma 20mm f/1.4 Reviews

    20mm f/1.4 DG HSM Art Lens for Canon EF is rated 4.5 out of 5 by 54.
    Rated 5 out of 5 by from Sigma hits a homerun with this one! Overall I am very happy with this lens. I already have wide angle zooms and wanted to go with a fast prime especially for my new Canon 5DS. The lens is well built and very solid and so far I am very happy with the sharpness and high resolution. Some people have complained about not being able to add a filter but I seldom use a polarizer on super wide lenses and the odds of me needing to use a ND are not great enough that I worry too much, you can do a lot in post production editing as well. The lens is on the heavy side but that is going to be the case when you have such a fast aperture and so much glass involved to render super sharp images.

    Rated 5 out of 5 by from Loving it!! I like night photography and am just getting into timelapse photography with my Canon 6d. I was considering a Rokinon as it has great reviews but I wear tri-progressive lensed glasses and its hard for me to manually focus. I also wanted to be able to catch wide scenic landscape shots with it once in a while as well. On to the lens. . . This is my first lens outside the Canon box. I am NOT at all disappointed. I am extremely pleased with this lens. Yes, wide open there is coma in the corners on night shots but I do not think its that bad. Stopping up a little pulls it into control. As a duel purpose lens it is nothing short of AWESOME!!

    Rated 5 out of 5 by from My number one (Sorry for my mistakes, i speak french) I used it last weekend for a wedding ... just incredible! Since i'm a journalistic type of photographer, this one was on my camera 85% of the time because it allowed me to focus on what i wanted without sacrifying the environement of my subject, wich is very important for a lifestyle photographer. Super quality image and color for portrait or landscapes.

    Rated 5 out of 5 by from As others ART series, from SIGMA... Spectacular! All my lenses are Canon L series or Sigma Art Series. Most of the sigmas are far superior in image quality over Canon's lenses. AF are pretty good and average speed, not as fast as the Canon's L series, but pretty acceptable for all kind of photography. On this particular lens, the quality is fat better than what I expected. It has some barrel distortion as expected, but it still acceptable. In outdoors it is not noticeable. The only downside over the Canon's is that is not weather proof and it is a little heavier than you will think. It worth every penny.

    Rated 5 out of 5 by from Another Winner From SIgma Yep, it is big. Yep, it is wide, and yep, it is fast. Sets a new standard for low-light WA performance. Exceeds the performance of my Canon 24/1.4 (Mk I) by quite a distance. I don't miss the ability to use screw-in filters, and the slip-on lens cap is secure; it fits tightly enough that it will not come off due to gravity. The only negative I can find is the rather significant focus adjustment required. On my Canon 6D body, there was significant back-focus at longer distances out of the box. Calibrating with the Sigma USB dock was straight-forward, and the offset at infinity for my body was -12, more than i expected. Still, the lens now hits very reliability from less than a foot to infinity.

    Rated 4 out of 5 by from About as expected There are plenty of technical reviews on the Web; I won't repeat specs here except to rectify an error in other reviews on this site. A couple incorrectly state the field of view. Per Sigma, FOV for the 20mm Art is 94.5 degrees. As often repeated, this lens is a solid handful. If you have, or have used Canon's 24-70 F/2.8L series II, you'll have a good idea of the heft and size of Sigma's 20mm F/1.4 Art. I knew the size and weight before buying, so I don't consider those cons. I've had this lens only a few days, long enough to run various tests to confirm it works as expected. It's quite sharp in center, softer at the edges and vignettes badly wide open. As stated in most reviews, these issues improve as one stops down. I found softness due to diffraction appears above F/8, but DOF at F/8 is enormous, so this won't present a problem for most photographers. Edge distortion is considerable, but not unexpected in a lens of this sort. This lens is not weather sealed; the usual cautions apply if you shoot in wet or sub-freezing conditions. I'd call it a bargain, sure to be very useful, and its problems aren't unexpected in this price range. For me, the pros outweigh the cons. My copy, on my Canon EOS 5D MkIII, back focused at all of the four distances specified by Sigma's calibration software (used with their USB dock). Given that the lens must be checked, unmounted from the camera, mounted onto the dock, adjusted, unmounted from the dock, mounted to the camera, rechecked (shoot and view the results), and that I had to repeat this a couple dozen times, the process can only be described as tedious and time consuming. In the end I got very good results, but it wasn't easy!

    Rated 4 out of 5 by from Best choice for Astro While this is not a one trick pony, it certainly shines in shooting the night sky. It is as sharp as any lens I have used, and since at night it is used on a tripod anyway, the lack of Image Stabilization is not too limiting a factor. It would have been turned off anyway. The very bright aperture makes for shorter shots, and lower ISOs, so a lot less grain in night sky shots. The lens is indeed substantial in the hand, but I found it enjoyable to use.

    Rated 4 out of 5 by from Perfect for astrophotog & night; heavy & large for hand-held I rented this lens for a week-long trip to the desert in Southern California and used it for both landscape and astrophotography. I rented the Canon mount version for my Sony alpha 7RII body and Metabones IV adapter, and it autofocused in decent light quickly and accurately. The lens is big, heavy, and highly capable. Whether its capability offsets the weight, size and one unfortunate design decision depends on what kind of photography you do. The negatives: The lens weighs about 2 pounds/950 grams, a lot more than my camera. It's 3.6/91mm in diameter and 5.1/130mm long. The front element bulges out and makes it impossible to attach screw-in filters. Sigma designed it with a permanent lens shade that makes it impractical to attach an adapter for Lee or Cokin filters. The lens shade protects that bulbous front element, but if the shade is damaged, the entire lens would have to be sent for repair. It would be better if the user could detach the lens shade and replace it with a new one, and it would be even better if the design allowed the use of an adapter for ND filters. The lens has significant curvature of field when you focus on close objects, although in use that wasn't a problem. The positives: Image quality is very high. The lens is beautifully built, with a large, smooth focus ring. The f/1.4 aperture allowed me to use focus peaking on the stars, which solved a problem that's common in astrophotography you can't rely on the infinity setting of a lens to accurate focus on the stars. And weight and size are a non-issue if you frequently use a tripod. The wide aperture is also very helpful in shooting architectural interiors. The lens has a 104 degree field of view, about 10 degrees wider than a 24mm lens. If you really need that extra width, this lens may be perfect. The obvious alternatives (at least for Sony alpha bodies) include the very good Sigma 24mm f/1.4, which weighs only 2/3rds as much and which will accept 77mm screw-in filters, but only has a 94 degree field of view. For the widest field of view, consider either the much less expensive, much lighter and more cheaply made manual Rokinon 14mm f/2.8 lens or the much more expensive, lighter and much smaller Zeiss 21mm Loxia, which is manual focus & aperture, but has almost the same field of view (and is available with an FE mount). The lens comes with a rear lens cap and a deep cylindrical front lens cap made of plastic that slips over the lens shade. You can buy a metal front cap, but the plastic one seems perfectly adequate.
