Sigma 202101 10-20mm f3.5 EX DC HSM Lens for Canon Digital SLR Cameras with APS-C Sensors black

The lens is of good build quality and it produces very good images. The extra-large 83mm opening seems superfluous because the actual lens glass is much smaller but I guess the extra circumference allows for a decent sized hood (included) without encroaching upon the 10mm wide angle shots and it channels as much light as possible into the lens. I've used the lens on a Canon EOS 7D and have produced some very pleasing Castle and Cathedral interior shots hand-held without flash (the constant 3.5mm a big enough aperture for most, but 2.8mm or bigger would be superb. I also took it to the lake district and from the 10mm wide angle perspective it crams a whole load of landscape into the vista. I also used my EFS 17-55mm and the difference within a landscape shot at wide end (10mm V 17mm) makes a huge difference and offers more creative options. It is also great for smaller spaces like car interiors and can make your living room appear cavernous! I would definitely use this if taking photos for selling property or vehicles. I give the 5 stars for value for money. The image quality is very good build quality feels great and good old Sigma include a quality padded case and lens-hood. Very much worth it at the price given the alternatives.

After much searching on the internet and reading reviews in magazines decided upon the Sigma 10 - 20mm f3.5 and after using it for some three weeks I am very pleased with the choice. I am using it with a Canon EOS 60D and it is slowly becoming my lens of choice, very rarely am I now using the Canon 17 - 85mm kit lens. The Sigma works well, obviously for landscapes but, I find superb for city work as well. The lens hood, a wide petal style, keeps stray reflected light at bay in the city and protects the lens well. Initially I used without a Polarising filter, but have now received my order and find that it really is an essential with this lens. Although the f3.5 setting gives acceptable results stopping down to f5 or f8 really makes this sing. Great lens and I will look to Sigma for further purchases.

I have never bought a 'wide' lens of this level, with a minimum focal length of 10mm it is as near to 'fisheye' as you want to get if you want to correct distortion. I looked at all the reviews here before buying this lens and found them honest and accurate. There is indeed softness towards the corners of the images as another reviewer stated but it is not in my opinion objectionable. The general points for me are that it has excellent contrast, very good saturation and delivers a very sharp picture (apart from those corners). I have put three images on the item page here for you to see. I got the lens on 11/10 and took the photographs on the 12/10 they are unedited and quite poor compositions compared to the other excellent images in the line, but they show what you get just by going out and pressing the button. Well worth the money and a fine lens.

This lens has a good solid feel to it. It looks to be at it's sharpest at f8/f10 and at 10mm there is an expected modest amount of barrel distortion, which fortunately Lightroom Lens Correction deals with fairly well. Out at 20mm the distortion is minimal and unless you are doing architectural work or have other prominent straight lines near the image edges then it's more than liveable with. All in all very happy with this lens and at under £300 it's good value for money.

I read a magazine article testing many lenses in this group and was surprised to find that this one produced significantly better results than it's rivals, including the Canon.I'd wanted a wide angle lens for a while thinking that I'd only use it for landscapes, which I don't do very often if I'm honest. When I received the lens I was more than happy with the results. The lens came with a case and a petal type hood, both good quality.The lens did take a bit of getting used to but now I find that if I'm not shooting wildlife I am usually using this lens. The zoom range is excellent, a wide f3.5 throughout the range gives great shallow depth of field possibilities and the guid quality is first class.There are a couple of minor niggles. Manual focussing is stiff and when used with video (the EOS650 has auto-focus when shooting video) the lens is jumpy and noisy, but like I say these are minor niggles.All in all a great value lens, it can well and truly hold it's own against all the competition.

Just been to Croatia and Serbia it seems a great and versatile lenses but I still need to check it out at home and photo some landscapes with a tripod at the right time of day to really review it but I am glad I bought this f3.5 as I have used it in low light (pushing the ISO) to get pictures at dusk and hopefully these will be good when viewed off camera hope that this helps but for anyone thinking about wide angle lenses go for one they are great for getting skies etc in

BIG FAT YES!Good lens,Good value for money,Very nice quality pictures.Nothing to complain about.Who not happy just buy better,pay 700,1000,1500 pound and more for lenses.If money is a problem so just enjoy what you got.100% RECOMEND this lens.One more thing, i know people who can afford camera and lenses that coast 4000-5000 pound,and dont know how to use it or use it just on auto mode,my pictures from my phone looks much better to compare with them😂Doesnt matter how much your camera staff coast,matters what you can do with that.Thank you and enjoy your photo.

Purchased this lens at the same time that I purchased a 70D. It fits the Canon 70D & 40D perfectly. Have tested the lens in low light with the images coming off a bit soft and also grainy (when upping the ISO). When used in daylight, the images produced are of good quality. There is the obvious distortion when not getting the angles right, but thats what you would expect from a wide angle.
