  • Designed for APS-C-Sized Sensors
  • 35mm Equivalent Focal Length: 28.8-56mm

The Sigma 18-35mm f/1.8 DC HSM Lens for Canon is a wide-angle to normal-length zoom lens that features a fast, bright constant f/1.8 maximum aperture. It is specifically designed for use with APS-C-sized sensors and provides a 35mm-equivalent focal length range of 28.8-56mm.

The lens integrates four aspherical elements into its construction as well as five Special Low Dispersion (SLD) glass elements to help minimize various aberrations and distortions throughout the zoom range as well as provide greater image sharpness and clarity. A Super Multi-Layer Coating has also been applied to lens elements to reduce surface reflections, lens flare, and ghosting to produce images with higher contrast and color fidelity. The lens barrel design is constructed from a Thermally Stable Composite (TSC) material that is akin to metal in texture and resistance to temperature and environmental changes while also remaining lightweight and compact. An internal focusing and zooming mechanism also helps to maintain a compact and consistent overall length and non-rotating front ring also better enables the use of circular polarizing filters. For control of focus, a Hyper Sonic Motor (HSM) is used to ensure fast, precise, and quiet focusing capabilities that are well suited to continuous shooting and movie recording.

For updating lens firmware and fine-tuning its nuances to best suit your personal shooting, this lens is compatible with the Sigma USB Dock. The dock allows you to specify certain parameters and other settings through the Sigma Optimization Pro software, such as AF speed and focusing limitations.

Art Lens Line
This lens is part of Sigma's Art line; deeming it well-suited to creative image making due to its large, constant f/1.8 maximum aperture and ability to produce aesthetic bokeh by way of a nine-blade circular diaphragm. The range of focal lengths it covers, from wide-angle to normal-length, is nicely situated for everyday and artistic shooting applications.
Optimized Lens Design
Four aspherical lens elements, as well as the incorporation of five SLD glass elements, help to minimize the appearance of distortions and aberrations throughout the zoom range and provide clear imagery with enhanced sharpness. A Super Multi-Layer Coating also benefits the image quality by reducing reflections and flare and contributing to greater overall contrast and fidelity.
Hyper Sonic AF Motor
The Hyper Sonic Motor provides fast, quiet, and smooth auto focusing that is well-suited for use with video applications. This AF motor can also be manually overridden at any time by rotating the focusing ring, giving you the ability to fine-tune image sharpness through manual focusing.
USB Dock
Compatible with Sigma's USB Dock and Sigma Optimization Pro software for fine-tuning your lens' performance, updating its firmware, and better suiting it to your needs.
Other Lens Features
  • Constructed using a TSC compound material, this lens is lightweight while also exhibiting notable durability and resistance to environmental changes.
  • An internal focusing and zooming mechanism helps to maintain a consistent overall lens length and a non-rotating front ring facilitates more efficient use of circular polarizers.

    Excellent lens for 70D (so far)

    I needed a low-light-friendly lens to go with my Canon 70D for an upcoming trip to Walt Disney World. I originally purchased the Canon 50mm f1.4, but discovered that the focal length was too tight for many uses (i.e. dinner table, wide-angle shots). Side note: I should have been more thoughtful about the 1.6 crop factor before purchasing the 50mm for this purpose.
    I read many reviews of the Sigma 18-35 f1.8 and decided this was the best lens for this use. I was a little apprehensive after hearing about some of the autofocus issues, particularly with the Canon 70D. But I read enough positive comments that I thought it was worth a try. I noticed that the Canon 50mm f1.4 also struggled to focus correctly when shooting wide open. I don't have experience with other cameras, but I presume that's to be expected for a crop-sensor with apertures wider than 2.8.
    I've had the Sigma 18-35 f1.8 for only a week, but it seems to perform EXACTLY as expected. Image Quality is top-notch and I don't seem to have any more shots with missed focus than I do with the Canon 50mm f1.4.
    I bought the USB Dock just in case the focus needs to be adjusted (how cool is that?), and I may do a little bit of tweaking after I use it more.
    Overall, this is a fantastic lens that seems like it will give even some of Canon's "L" lenses a run for their money.
    Yes, the focal length is ONLY 18-35. I don't see that as a negative: it's clearly advertised as such. Yes, it's heavy (810g/1.75lbs): good glass and (some) metal is heavier than cheap glass and (mostly) plastic. There is NO perfect lens - there are always tradeoffs! I think Sigma nailed it with this lens and I think anyone with reasonable expectations will be very pleased with it!

    I'll plan to post a follow-up after living with it a bit longer. But my initial impressions are very favorable!

    I have to give props to B&H - this lens was(is?) out of stock everywhere I looked. It was initially backordered, but B&H was able to ship within 1 week of when I placed my order. Well done!!

    This is a follow up to my enthusiastic review dated 3/31/14. After a few weeks of use, the lens began to have focus issues, enough to the point that it could not focus on an area that was clearly defined, with easy to discern colors. The lens took to "hunting" back and forth searching for a focal point. I purchased the USB Dock to try and calibrate it myself, but that task was tedious for a lens that should come ready to use. I contacted Sigma and received confusing info (the website lacked easy to follow instructions for returns and tracking). Regardless, I sent the lens back for calibration.Sigma calibrated the lens and so far I have not had any issues. However, I'm not convinced that I will not have problems in the past. To spend $[*] and receive a lens that required calibration was bad enough. To find that I had to send the lens back at my expense, without verification of receipt or repair added to the insult. Though the lens appears to be working well at this point, I cannot recommend one put $[*] on the line.

      Comments about Sigma 18-35mm f/1.8 DC HSM Lens for Canon:

      I've had this lens now for 2 weeks. I recently purchased a C100 and got the Sigma 50mm art and this lens. I love the way it looks on the camera and the build is SOLID. I was needing something with a wide angle because the 50mm performs like an 80mm. I love how wide the aperture is because I work in a lot of low light situations. I haven't tested out the auto focus when I calibrate the lens to the Sigma USB dock. I've heard the the autofocus significantly improves on the C100 when this is done. There is a noticeable distortion when on the far end of the zoom. This is mostly noticeable when you have blatant linear objects in the frame. That being said, the other end of the zoom is perfect. I'll be getting an entire Zacuto recoil rig and this will be the primary lens. I'm excited about this combo and I think it will fit perfectly in the system!

      Comments about Sigma 18-35mm f/1.8 DC HSM Lens for Canon:

      This is a fantastic lens for APS-C cameras. It takes very sharp photos on my Canon 70D, even wide open at 1.8. I was worried about focus reading some other reviews of this lens, but I have found my copy to be quick and accurate, without the need for the USB dock (though I may do some micro adjustments through my camera). I have only used this lens a few times, but I really enjoy the results.

      Comments about Sigma 18-35mm f/1.8 DC HSM Lens for Canon:

      First off, this is an amazing lens. Being the first lens that has a fixed f/1.8 aperture on a zoom lens pretty much made all my prime lenses obsolete in that zoom range. The bokeh is fantastic, image quality is on par with L series glass that I have, and the construction of the lens itself feels wonderful. Those are all the great things about the lens, but it isn't 100% perfect. After using the lens for a better part of the year, one thing sticks out the most for me. The auto focus in low light, dark scenes seems to be all over the place. Your subject(s) have to be relatively still and your AI focus very on point for it to be focused correctly. Be it, in daylight and normal lighting, the AI works well. Although the more I've been using it at night, whether it be engagement or wedding photos or just trying to capture moving subjects, I tend to miss more than half my shots. It's almost a struggle for the AI to focus correctly that I rather change to manual and track my target. Comparitely to L series glass, this Sigma doesn't match up as far as low light Autofocus is concerned. Once I switch up to the Canons, I instantly notice how fast the lens is tracking back and forth to follow a subject and doesn't have to struggle determine where they are. If you're worried about using it with a speedlight in low light situations like snapping away at a wedding on a dance floor, with a flash attached on ZONE AF, I didn't notice having too many problems. The pictures are definitely usable, and the AI finds the subjects faces alright. Usually the faces are closer so it's easier for the lens to pick up. The problem is mostly anything beyond 15-20 feet, the lens struggles to find anything on Zone AF, where you have to go into Manual AF point to make sure the lens is looking in the right area to focus. Even then, the lens is constantly move back and forth trying to find the subject even if they're very still. Everything else besides that, I am absolutely in love with this lens. It is on my camera 90% of the time. If you can afford L series glass for low light, then by all means it blows this lens out of the water. But for a APSC lens, this is my favorite lens by far. If you can deal with the low light auto focus issue, I say purchase this and never look back. You'll definitely love this lens for all that it can do!

          Once upon a time, you had to buy a full frame camera to get a lens this good. But Sigma has changed the game with their new lenses for crop sensor cameras. The reality is, the vast majority of cameras today are crop sensor, and with this lens, in it's range, you can shoot on par with the pro's. Always wondered what that fancy L glass with the 2.8f was all about? Try this lens and see. 1.8f on a crop is equivalent to 2.8 on a full frame body. Bokehlicious. The pro's are raving about this lens for good reason.

                Comments about Sigma 18-35mm f/1.8 DC HSM Lens for Canon:

                I had to max out my Canon 70d's micro AF adjustment for horrible front focusing, it hits about 80% of the time now, unacceptable. I feel this lens has a hard time focusing, HOWEVER, if everyone can correct for it in their cameras or with Sigma's dock, then it's clear, they send them out either un calibrated or worse, de-calibrated, forcing you to buy their dock to fix the problem. One of those two MUST be true, how sad.It does however focus well in live-view, but right now only the 70D has decent live-view AF. It is tack sharp then, but it's slower to focus and uses way more battery power, albeit harder to pick where you want to focus.So, you'd think this lens would be great for wedding video (what i bough it for) WRONG! It does what OLD Sigma lenses do, and ZOOMS in the opposite direction! Need to zoom out? go ahead and try it, OPS you just zoomed in, yeah that'll look professional in your video! I had to put a cheat sheet sticker on my tripod head so I don't mess it up again. ALL my other lenses are Canon, this is impossible for me to get used to. If sigma is going to sell the most of one mount, don't you think they'd match the zoom direction? This is horrible! But most brands zoom the Sigma way, so they were CHEAP and didn't switch it.This lens is for people who do not shoot demanding work. This lens is not for professional photography (I guess i'm keeping my 5D3) nor is it for professional video.If you are a hobbyist, great, buy this lens. It is very sharp if you can get it focused.Oh yeah, it's heavy. Now, just skip over that and tell yourself you don't care if it's heavy just like I did. Let me re-phrase... it's much heaver than you will expect it to be. THEREFORE... won't work on my glidcam 1000, like my 70d + 10-18mm lens (great combo in good light btw).Being heavy might help you keep it stable.-1 star for backward zoom (some people will take 5 off for this)-1 star for un correctable slowish, inaccurate AF-1 star for shipping lenses that aren't calibrated to sell the dock to people+1 star for sharpness+1 star for build quality, the zoom is so smooth, BUT does make it hard to zoom quickly if needed.I bought it elsewhere (paid more too) cause BH was out of stock. I think they are going to get a return. I'll do what so many others have done and toss the DSLR for a large sensor video camera for professional video.In this review i mention professional work. I'm a CPA M-F, but what i mean by professional is someone who makes money shooting. I only pull in $15k/yr but still, I consider that professional work. Sure there are much more costly options out there, but for even semi pro work this lens does not cut it. Their 35 f1.4 is killer, however. Will buy the 50mm soon too.

                Amazing lens. Sold my canon 5d mk III and bought a 70d just so I could use this lens. If you love strong contrast and poppy colors then you will love this lens. Works amazing wide open. Super creamy bokeh. You will love this lens. If I had to find a negative it would be the size and weight of this lens - not very conducive for stuffing in your backpack and traveling.

                  Very clean images, even open at 1.8. The auto-focus works well, although in low light it does have some difficulty. My only complaint is that the zoom ring needs a bit more force to turn it than any other lens I've used, and that makes quick zooming in/out just a teeny bit harder/slower than I'd like it. Apart from that, I'd highly recommend this lens.

                    Comments about Sigma 18-35mm f/1.8 DC HSM Lens for Canon:

                    I needed a low-light-friendly lens to go with my Canon 70D for an upcoming trip to Walt Disney World. I originally purchased the Canon 50mm f1.4, but discovered that the focal length was too tight for many uses (i.e. dinner table, wide-angle shots). Side note: I should have been more thoughtful about the 1.6 crop factor before purchasing the 50mm for this purpose.
                    I read many reviews of the Sigma 18-35 f1.8 and decided this was the best lens for this use. I was a little apprehensive after hearing about some of the autofocus issues, particularly with the Canon 70D. But I read enough positive comments that I thought it was worth a try. I noticed that the Canon 50mm f1.4 also struggled to focus correctly when shooting wide open. I don't have experience with other cameras, but I presume that's to be expected for a crop-sensor with apertures wider than 2.8.
                    I've had the Sigma 18-35 f1.8 for only a week, but it seems to perform EXACTLY as expected. Image Quality is top-notch and I don't seem to have any more shots with missed focus than I do with the Canon 50mm f1.4.
                    I bought the USB Dock just in case the focus needs to be adjusted (how cool is that?), and I may do a little bit of tweaking after I use it more.
                    Overall, this is a fantastic lens that seems like it will give even some of Canon's "L" lenses a run for their money.
                    Yes, the focal length is ONLY 18-35. I don't see that as a negative: it's clearly advertised as such. Yes, it's heavy (810g/1.75lbs): good glass and (some) metal is heavier than cheap glass and (mostly) plastic. There is NO perfect lens - there are always tradeoffs! I think Sigma nailed it with this lens and I think anyone with reasonable expectations will be very pleased with it!

                    I'll plan to post a follow-up after living with it a bit longer. But my initial impressions are very favorable!

                    I have to give props to B&H - this lens was(is?) out of stock everywhere I looked. It was initially backordered, but B&H was able to ship within 1 week of when I placed my order. Well done!!

                    Great companion for my Canon 70D. Takes sharp images even in low light thanks to the f/1.8. Nice depth of field and the best part is the stunning video quality. Again because of the constant f1.8. Love the lens!

                    Comments about Sigma 18-35mm f/1.8 DC HSM Lens for Canon:

                    I waited about a year before purchasing this lens. I heard there were focusing issues and such so I wanted to wait until they straighten out the kinks. I wanted this lens for my C100 to get that wider angle and fast aperture. Here are my findings after I finished a narrative shoot with it last week.

                    1. It's sharp wide open at f/1.8. Great!
                    2. While some people say it's pretty hefty, I say it's lighter than my Canon 24-70mm f/2.8(version 1).
                    3. I like the smooth focusing
                    4. My C100 has the upgraded dual pixel AF. When I first got the lens on, it worked great. Very quiet dual pixel AF. On the day of the shoot, it wouldn't auto focus. Even after turning the C100 on and off. When I got home, I removed the lens and then back on again and the dual pixel AF started working again on the C100. Very weird. It's happened only once so far.

                    Overall, I am satisfied with the quality that I'm getting with this lens on the C100 for the price. It has a very short focal length, though, so I still find myself switching to the Canon 24-70mm f/2.8 (version 1) to get that extra reach when I need it.

                      When the stars all align and there's a lot of light, some shots will be tac sharp; otherwise, you will experience softness... Inconsistent AF; noisy and slow-hunting at times. Disappointed with this Art lens offering.

                        This is a follow up to my enthusiastic review dated 3/31/14. After a few weeks of use, the lens began to have focus issues, enough to the point that it could not focus on an area that was clearly defined, with easy to discern colors. The lens took to "hunting" back and forth searching for a focal point. I purchased the USB Dock to try and calibrate it myself, but that task was tedious for a lens that should come ready to use. I contacted Sigma and received confusing info (the website lacked easy to follow instructions for returns and tracking). Regardless, I sent the lens back for calibration.Sigma calibrated the lens and so far I have not had any issues. However, I'm not convinced that I will not have problems in the past. To spend $[*] and receive a lens that required calibration was bad enough. To find that I had to send the lens back at my expense, without verification of receipt or repair added to the insult. Though the lens appears to be working well at this point, I cannot recommend one put $[*] on the line.
