Product Highlights
  • For Olympus & Panasonic Digital SLR
  • Zoom Super Wide Angle

The Sigma 10-20mm f/4-5.6 EX DC HSM lens offers an ultra-wide zoom solution to digital cameras, and was exclusively designed to suit the characteristics of digital SLR cameras. The super wide-angle capability of this zoom lens (equivalent range of approx. 20-40mm when used with a Four Thirds digital SLR camera) makes it a very powerful tool for both indoor and landscape photography.

DC lenses are exclusively designed for digital SLR cameras. The image circle (rear of lens) is made to match the smaller dimensions used for the image sensor on digital cameras. As a result, these lenses are also more compact and lightweight, and are better matched to digital SLR cameras.

    Great lens for BMCC

      Comments about Sigma 10-20mm f/4-5.6 EX DC HSM Autofocus Lens for Four Thirds System:

      I purchased this lens for the Blackmagic Cinema Camera. I have a set of Nikon lenses, though the crop factor of the BMCC made my widest Nikon a 70mm. The Sigma 10-20 is surprisingly sharp with contrast on par with any of my Nikon glass. I have not noticed any distortion on the edges. The lens feels balanced on the BMCC and offers a wonderfully wide field of vision. This is not an exceptionally fast lens and doesn't offer much shallow DOF, though is ideal for landscape and wide views. Very good lens at this price point. I recommend this lens to any BMCC user.

          I actually got the Sony/Minolta mount version, not the 4/3 version ... that said, I've been really impressed by the image quality from this lens. It's tack sharp, with great color and contrast. I've had other ultra-wide zooms before, but this lens trumps them all. I can't say enough good things about it.

            Comments about Sigma 10-20mm f/4-5.6 EX DC HSM Autofocus Lens for Four Thirds System:

            I bought this lens just over a year ago (used, perfect condition, [$]) and have not regretted it one bit. My wife also has one for her Canon 5D, she obviously has the proper 10-20mm range as opposed to 4/3 20-40mm.Landscapes are much sharper and clearer compared to my Olympus Zuiko 14-42mm, wider too. Amazed at the difference between the 10mm end of the Sigma and the 14mm end of the Zuiko.Focusing is fast and precise. I love the switch auto/manual focus button and the focal length window.Should you buy it? Heck yes! Worth every penny.

                Comments about Sigma 10-20mm f/4-5.6 EX DC HSM Autofocus Lens for Four Thirds System:

                This is my first wide angle DSLR lens and I use it on an Olympus E-30. I am a pro-sumer level photography guy. I did some comparison between this lens and the Olympus 9-18mm wide angle and was really impressed with how little distortion there was with the Sigma Lens, at least in the photos at flickr. The Olympus 9-18 had very little as well but my budget fit better with the Sigma lens.

                So far I love it, and have used it for a baby shower at work and some general outdoor shots. The focusing mechanism is smooth and feels like it will remain snug for a long time. The af functions perfectly and the mf works great too. There actually is very little distortion at the edges of photos with this lens as well, which pleased me. Overall I like this lens a lot and look forward to having a nice wide angle in my bag.

                A great first lens at a reasonable price to explore wide angle photography. Great for group pictures, parties and architectural interiors and exteriors. Crisp throughout the zoom range. Flash falls off at the edges at 10mm, but a +0.3 boost on the flash compensates nicely indoors.

                  I am a photo enthusiast that shoots a lot of track and field events, but I was looking for a lens to round out my lens package for panoramic shots and interior shots. The 10-20mm lens when paired with my Olympus E30, gives me the lens that I needed for shooting in a tight environment and for landscape panoramic shots. So far, I have not found anything that I dislike about the lens.

                  Fun lens for architecture/interior design photography and other cool compositions where you get plenty of light. This is my first non-Nikkor lens, and I must say I'm very satisfied with Sigma's quality. Comparable Nikkor lens is at extra [$]. I think this is a great alternative for people that do long exposures and not requiring low light situation and fast action.

                          I gave done some test shots with the 10-20. Sharp edge to edge. Good contrast and color rendition. I'm taking it to the Grand Canyon next week. I think I gonna like it alot!

                          I couldn't recommend this lens highly enough. Seems to be sharpest around f11 and has noticably distorted edges at 10mm but nothing too major. I used it today on a walk around London and it produced some great results. Get one, you won't regret it.

                            Comments about Sigma 10-20mm f/4-5.6 EX DC HSM Autofocus Lens for Four Thirds System:

                            I travel and carry as few lenses as possible. This lens allows me to use the same filters as I do with my SIGMA 135-400mm 4/3 System Zoom. With the 3 lenses I carry I am able to tackle any subject matter. Sharp, smooth focus. Though a bit slower than the competition, the lens performs well in all light levels. Images are GREAT and I am very pleased with this lens. Sigma works overtime to produce great lenses at very reasonable prices.

                              I travel extensively and I need a good product at a good price and on occasions I need it fast. Well this 10-20mm Digital 4/3rd System Wide Zoom is just the ticket. Super quite HSM autofocus, good and easy to see manual focus, and the lens ROCKS on my Olympus E3. B&H Photo is awesome. Ordered and shipped within 24 hours - In my hands within the week! Great service as always. I will be back!
