Product Highlights
  • Canon EF-S Mount Lens
  • Aperture Range: f/1.4 - 16
  • For APS-C Format Cameras
  • Standard Focal Length Prime Lens
  • Minimum Focus Distance: 11.8" (30 cm)
  • Hyper Sonic Motor for Smooth Autofocus
  • Thermally Stable Composite Material
  • Brass Bayonet Mount

The 30mm f/1.4 DC HSM Lens for Canon DSLR Cameras from Sigma is a prime lens designed for Canon APS-C format cameras. Its 35mm focal length equivalent is 45mm which places it in the category of standard focal length lenses. With its particularly fast maximum aperture of f/1.4, the lens will perform very well in low light situations and provides shallow depth of field focus. With updated optical configurations (9 elements in 8 groups), as well as rounded aperture blades, the lens delivers sharp detail and nice background bokeh. Its minimum focus distance is 11.8" (30 cm).

The lens’ optimized light distribution helps to minimize field curvature preventing a loss of image quality at the edges of photographs and its double-sided aspherical lens element minimizes spherical distortion. A rear focusing system combined with a newly developed autofocus algorithm and Hyper Sonic Motor provide smooth and accurate autofocus. Fulltime manual focus is also supported. As part of Sigma's "Art" line of lenses it is compatible with Sigma's USB Dock, which enables firmware updates and focusing adjustments.

Fast maximum aperture of f/1.4 allows fast shutter speeds for clear low-light imaging and shallow depth of field focus.
A Hyper Sonic Autofocus Motor (HSM) offers fast, smooth and quiet autofocus.
Constructed with Thermally Stable Composite Material (TSC) which performs well in extreme temperatures, reducing the expansion and contraction of the internal lens barrel.
As part of Sigma's "Art" line of lenses it is compatible with Sigma's USB Dock, which enables firmware updates and focusing adjustments.

    I got to use this lens for a short while. I love Sigma's new design of their lenses. Very slick and clean looking.
    I've never used the predecessor to this so I have no comment on that subject.

    Pros: Light and small packing a large aperture. A very reasonable 30mm. Excellent bokeh. Looks pretty sharp wide open.

    Cons: Still a significant bit of color fringing wide open. Even stopped down it's clearly present at 100% but not as bad. Not to worry too much since post can remove a lot of it.

    Side note: I used this on my 5D Mark III. It may say EF-S but it will mount up to a full frame camera and work fine. There is no significant vignetting either.

    As far as DOF goes. Don't fret, since it's 30mm even wide open you still have good working room.
    At 4ft/1.2m subject distance you have a 3.3in/8.5cm DOF.
    At 8ft/2.4m subject distance you have a 1.16ft/35cm DOF.

    Comments about Sigma 30mm f/1.4 DC HSM Lens for Canon DSLR Cameras:

    I was looking for a wider angle lens to replace my Canon 50mm 1.8 lens. After reading review after review and comparing the Sigma 30mm to the Canon 35mm 2.0 and 28mm 1.8, I settled on this lens. The focal length on this lens is perfect for photographing in small spaces and the bokeh is stunning. The other canon lenses mentioned above do not even compare when it comes to bokeh. The one downfall of this lens is that it does have a hard time getting sharp images in low light, but the Canons 28m and 35mm were not much better. I love this lens and all that I am able to capture with it! This lens is built solid too. Even the canon 35mm (for $) felt like a toy compared to this lens!

      Comments about Sigma 30mm f/1.4 DC HSM Lens for Canon DSLR Cameras:

      While there may not be a "perfect" lens in the world, the combination of features and price make this 30mm come darn close!

      Having shot with the predecessor to this iteration of Sigma's 30mm f/1.4 I had a good idea of what to expect, though I've been thrilled with the improvements in build quality with this version. Metallic body and noticeably smoother focus ring make this lens a joy to shoot with. Auto Focus is acceptably fast and quiet, no issues there, though I'm frankly more of a manual focus puller...

      Pair this lens with a decent body, monopod/tripod, and maybe an ND filter for some real outdoor action, and you've got a pretty powerful photo/video tool.

      Comments about Sigma 30mm f/1.4 DC HSM Lens for Canon DSLR Cameras:

      The Japanese family company Sigma has been producing third-party lenses for decades already. Thus far their policy has been offering "good enough" products for prosumers on a budget. At the price, the products were good but not comparable to the original brand quality.

      With the 'Art' series lenses this has changed.
      Their flagship 35mm f/1.4 for full frame bodies has impressed the testers and the users all over the world. It is not cheap., just under 1000 dollars but its results are superior to for example the Canon 35mm f/1.4 L, which is an old design.

      I got the 30mm f/1.4 for my SL-1 which has been my reserve body.
      The first shots I got took me by surprise: This thing is clearly something not seen before. The pictures are clear, crisp, color neutral and, what seems to be the most important thing for people nowadays: SHARP.

      The picture quality is far superior to all my other lenses, and I got 'L'.

      The lens is quite big and heavy even for its size. There is a lot of high quality glass inside. The body is constructed of composite that feels like metal and is supposedly immune to changes of shapes and measures according to the temperature.
      It looks good, like something with a German family name starting with a Z or an L.

      The focusing is fast and exact. The ultrasound motor seems to bother some dogs but this is the same with Canons USM.

      This is my favorite lens. It changed the status of the EOS SL-1 completely as the results it produces are on par with the 5D III with the old 24-70 screwed on...unless, of course, you are making wall-size posters.

      Sigma is about to launch an 'Art' series 50mm f/1.4 which has tested better than lenses with 4 times the price tag. Maybe there will be a 85 mm 'Art' lens as well. This means I am not getting the Canon 85mm f/1.2 but I'll wait for the Sigma.

      For the EF-S (APS) sensor cameras this is the thing.
      Arigatoo, Sigma, aistimas!

        Comments about Sigma 30mm f/1.4 DC HSM Lens for Canon DSLR Cameras:

        First off, I will say I am an armature photograph and see photography as a hobby rather than a career. For my purposes, this lens is fantastic.

        To start, the build quality of this lens is amazing. I upgrade to this lens from a 40mm Canon pancake lens with a max aperture of 2.8. Compared to that lens, it's weightier and larger, however I love that about this 30mm. The 40mm felt toyish to me and was constructed of plastic; this Sigma is made mainly from metal. To me, that's not a huge deal because like many of you reading this review, we take good care of our equipment, however the Art lens feels more professional and if you were to take it out on the trail, it could withstand a bump or two. Compared to other Sigma lenses I own, this is by far the best constructed; I also own the 10-20mm and the 18-250mm. The 10-20 feels well built and hefty, but 18-250 is frankly cheap feeling, however you should have no concerns about this 30mm.

        What I love the most about this lens is the fantastic depth of field it provides. The bokeh of the lens is smooth as silk and allows the subject of the image to be captured brilliantly. It isolates the subject and forces the viewer to examine it, rather than what might be behind it. Also, if there is light behind the subject, the bokeh of it is spherical and not at all angular. The 1.4 max aperture is a great feature and the low light performance is incredible. It makes taking photos with friends and family at gatherings much more enjoyable and less frustrating. Since the lens lets in more light, you can capture your photos with a shorter shutter speed making your images less shaky and crisper when their on screen. However, there are other lenses out there that are cheaper and also shoot at f/1.4, (even the Canon f/1.4 50mm is cheaper than this), so why look at this lens?

        Compared to other f/1.4 lenses on the market, the 30mm obviously lets you capture more in the frame. On a crop sensor, this is huge. Almost every crop sensor Canon makes has a multiplier of 1.6, so really this 30mm lens is the equivalent of a 48mm on a full frame camera. I love this focal length. Even with aforementioned 40mm pancake lens I had, I found myself clearing a path as I constantly had to back further away from my subjects to capture the entirety of what I wanted. At times I was roughly 12 feet away from a group of four people if I wanted to fit them all in... and that was on a 40mm... I'd be even further away from subjects on a 50mm, which really led me to this lens.

        What if I wanted to shoot a small subject and wanted to fill the frame? The 30mm would be disadvantageous in this scenario right? Well... not really. The lens has a minimum focusing distance of only roughly a foot. If I did want to get an isolated image of a still, I could shoot it closer with this lens, filling the frame to a distance which is close to that of what a 50mm lens would achieve with a minimum focusing distance of 1.5 feet.

        There have been complaints about front focusing / back focusing with this lens... I have had no problems with this. Even so, Sigma does make a USB mount for Art lenses where you can adjust them on your computer. I do understand though that when you spend close to 500 dollars on a lens, you should not have to buy another accessory to perfect it; luckily I don't have this issue, but it's nice to know that 5 years from now if I am noticing discrepancies, I could correct for it.

        The video quality seems fine - I rarely shoot video - however the main issue that I have is that its noisy when auto focusing. The mic does pick it up and it is off putting when viewing videos. For me, not a big issue as I mainly shoot stills.

        As an armature photographer, I am very happy with this purchase and upgrade from my 40mm pancake. At the end of the day, this lens takes super sharp images, is extremely versatile (more so than a 50mm), adds great DOF to images, performs fantastically in low light, and is built strongly enough to serve you well into the future. There is really not much more a hobbyist could ask for.

          I'm not a professional photographer by any means, and when shopping for a fast prime lens I shopped around a lot. I'm extremely happy with this purchase. After playing around with it for a couple of days, my friends that do photography for more of a living started making comments like "Great bokeh" right away, which is awesome to hear.

            High quality construction, beautifully crisp photos, perfect field of view (with Canon EOS 70D in my case) for walking around photography. With this kind of crispness you don't even miss the zoom, and it's far smaller and lighter than zoom lenses. Great indoors with F1.4 capability; obviously this won't be the lens you need for wildlife or distance shots.

            I currently shoot on a Canon T1i, and what I've always learned is to invest in the glass before the body. This was the perfect option for a crop sensor photographer like myself, and right out of the box I loved this lens! The autofocus is fast and super super quiet. It's heavy, but that doesn't change my opinion one bit about this lens. It's a great step for people who are wanting to get a prime lens that will do more than what the Canon 50mm 1.8 will do or the kit lens. If you are on the border of weather or not to get the lens, GET IT!

            Comments about Sigma 30mm f/1.4 DC HSM Lens for Canon DSLR Cameras:

            This is a really great lens. Firstly I had heard the previous Sigma 30 was good - but had autofocusing issues - and to my luck [*] Warehouse deals shipped me the old version by mistake (trying to con people if you ask me). The old version of this lens was horrible, it's focus wheel was really stiff and impossible to use, and the autofocus was absolutely terrible.This new one is fantastic! Razor sharp, Amazing Bokeh, Great autofocus - did not have same issues as previous version (note: I did apply a tiny AF Microadjustment to fine tune it), smooth focus ring. It works fantastically as a 50mm equivalent on a crop sensor (in my case a 7D) and is well built.If anything I would say it is a little heavier than I had expected - but I the performance outweighs that by a long shot.I have not tried it for video yet - but you would have a hard choice between this and the Sigma 35mm A.Buy this lens - you won't be disappointed

              I like to travel light, but my first priority is image quality. I found this lens to be the ultimate compromise with 30mm probably being just about right for general (non-sports, wildlife, etc.) photography with the added benefit of the large aperture. So far I haven't found the need for wider and my next focal length is 100mm.
              No "third-party" issues whatsoever.

              Although this is 30mm, it's really like 50mm for my 60D, since the sensor is smaller. I take this lens everywhere or only lens that I use.
              Takes beautiful shots with clarity. If you are taking artistic shots this is IT.

                Comments about Sigma 30mm f/1.4 DC HSM Lens for Canon DSLR Cameras:

                I took a trip to Catalina island this past weekend on vacation and thought to bring along this lens and put it through its ropes. Let me just say that i am EXTREMELY impressed with this lens. Due to it having a lack of solid reviews and being a relatively new lens i will admit that i was very worried about buying it. However all worries were put aside after i snapped over 1000 photos and took hours of video on my trusty 60d with this lens. This lens is not only sharp but truly proficient in low light. The lens has a very solid build quality, i sometimes feel that i could drop it and it wouldn't break! The true reasons i got this lens was to have a 50mm equivalent lens for video. This lens is absolutely AMAZING for video. It produces a very beautiful image that makes your videos look STUNNING. I would highly recommend this lens for all crop sensor users!

                  This lens is awesome and very fun. The focal length is great for taking every day photos. The depth of field at 1.4 is very small and it gives you great bokeh. Not to mention how great it is for taking photos at night with no flash. Overall the lens is sharp and it produces rich colors. The only downside is that it's a little soft when it's wide open at 1.4 but close it to 1.8 and it's sharp again. I just wish it was a little bit cheaper but if you have the extra cash then it's a great buy.

                        Comments about Sigma 30mm f/1.4 DC HSM Lens for Canon DSLR Cameras:

                        I got to use this lens for a short while. I love Sigma's new design of their lenses. Very slick and clean looking.
                        I've never used the predecessor to this so I have no comment on that subject.

                        Pros: Light and small packing a large aperture. A very reasonable 30mm. Excellent bokeh. Looks pretty sharp wide open.

                        Cons: Still a significant bit of color fringing wide open. Even stopped down it's clearly present at 100% but not as bad. Not to worry too much since post can remove a lot of it.

                        Side note: I used this on my 5D Mark III. It may say EF-S but it will mount up to a full frame camera and work fine. There is no significant vignetting either.

                        As far as DOF goes. Don't fret, since it's 30mm even wide open you still have good working room.
                        At 4ft/1.2m subject distance you have a 3.3in/8.5cm DOF.
                        At 8ft/2.4m subject distance you have a 1.16ft/35cm DOF.

                        Pros

                        Comments about Sigma 30mm f/1.4 DC HSM Lens for Canon DSLR Cameras:

                        Granted, this lens has only been available for a very short time (as of this writing) and I'm sure that many more reviews will follow; but for now I'll try to inform and maybe humor you with what follows.

                        My goal was to be able to use this lens as my favorite walk-around people-taking lens. That's already happened. The 30mm with 1.6x crop factor on my Canon 7D maintains reasonable space between camera and subject.

                        Wide open and focused (more on that in a sec) the lens produces an incredibly sharp image with a DOF you can measure in fractions of an inch. Okay, maybe an inch. Focus on the tip of the nose and the eyes show blur. And the hair? Forget it at F1.4. On the bright side, if this is what you want or are forced into it with low light conditions, it will work. There is some purple/magenta fringing at large aperture, especially at bright edges. On the plus side the bokeh on this lens is beautiful. The out-of-focus areas have a softness that I find soothing, almost serene in effect.

                        Autofocus was almost impossible to control at F1.4 without carefully locking in on my subjects and framing the image properly (I was using AI focus). Stop down to 2.8 and the DOF becomes reasonable. Autofocusing at 2.8 and smaller wasn't an issue and I couldn't tell any difference in sharpness between AF and manual focusing. Autofocus speed was faster than I could frame and shoot, certainly good enough for all but the fastest sports shots.

                        All told, a very good, fast lens for the price. It produces far better images than my wide-angle zoom lens, but I lose the zoom.

                        Comments about Sigma 30mm f/1.4 DC HSM Lens for Canon DSLR Cameras:

                        I owned both the EX DC and this art lens. I haven't had much time to play around with the new lens, but so far, I have noticed some differences.

                        1) The build quality feels superior, the focus ring is much smoother (which I love)
                        2) I believe (though I'm no expert) that this lens is sharper than its predecessor. The color fringing wide open (F/1.4) seems like it has been improved upon.
                        3) The glass diameter has been drastically decreased. I think aesthetically not as pleasing, but possibly has physical benefits with better glass.
                        4) Focusing is much the same (I don't know what kind of focusing problems will come about, but I have had none so far), it is very fast and quiet.
