Sigma - Sigma AF 10-20mm F4-5.6 EX DC HSM for CANON - 201101
Amazon.com Product Description
Designed exclusively for Canon digital SLR cameras, the ultra-wide-angle 10-20mm offers a view from 102.4 to 63.8 degrees, making it ideal for landscape photography and other vast applications. The lens is distinguished by its three special low dispersion (SLD) glass elements, which effectively compensate for color aberration, and its aspherical lenses, which provide maximum correction for distortion and various aberrations. As a result, the lens produces an extremely high image quality throughout the entire zoom range. The HSM-equipped models, meanwhile, produce fast autofocus (AF) speeds and quiet shooting while still letting you perform full-time manual focus. Other details include a minimum focusing distance of 9.4 inches at all focal lengths and an integral petal-type hood to block out extraneous light.
Lens Elements and Coating
The new multilayer lens coating and lens design reduce flare and ghost--a common problem with digital cameras--while also creating an optimal color balance throughout the entire zoom range. At the same time, the lens offers three SLD glass elements that effectively compensate for color aberration, along with a piece of glass mold and two hybrid aspherical lenses that offer excellent correction for distortion and all types of aberration.
Inner Focusing System and HSM
The lens incorporates an internal focusing system that eliminates front lens rotation, letting you use a petal-type hood to protect from additional glare. And models equipped with a Hyper-Sonic Motor (HSM) produce silent, high-speed autofocus and full-time manual focus for Sigma, Canon, and Nikon D-mount lenses.
Best Consumer Lens
The Sigma 10-20mm lens is so respected that it was named the best consumer lens in Europe (2006) by the Technical Image Press Association (TIPA), a collection of 31 publications from 12 countries. According to TIPA, the 10-20mm lens offers a versatile range of wide-angle focal lengths, a good optical performance, and a budget price, making it an excellent investment for owners of DSLRs with APS-C format sensors. Its sharpness remains constant throughout the zoom range, and its compact size makes it an ideal companion for shooting travel, landscapes, or architectural subjects.

Sigma 10-20mm f/4-5.6 EX DC HSM Lens for Canon Digital SLR Cameras Reviews

Of these, sigma 12-24 is the only one which is usuable on a full frame sensor (canon 1d, 5d, possible future cameras). There is sizable difference in field of view between the 10 mm, and 12 mm. and the tokina is closer to 13 mm on its wide end. The sigma retails for about 2/3 the price of the canon. Optically they are very similar, with the canon having a larger maximum aperature, which is generally not important in a wide angle lens. The built construction is EX, they higher line of sigma, and it excellent. The focus motor is HSM, making it fast, and very accurate. Resolution chart show the sharpness to be very close to that of canon. The color and contrast is excellent, the flare and chromatic abberation genenrally well controlled. A fun lens to use, and excellent value. 51 of 52 people found the following review helpful: High Quality Doesn't Have to Equal High Cost, By This review is from: Sigma 10-20mm f/4-5.6 EX DC HSM Lens for Canon Digital SLR Cameras (Camera) I wanted an ultra wide angle lens for my new Canon EOS 40D, but I didn't have the money to purchase a high cost Canon ultra wide lens. Careful research kept pointing to the Sigma 10-20mm f/4-5.6 EX DS HSM lens. At 4 to 5.6, this lens is slightly dark, but for an outdoor lens I figured lighting wouldn't be much of an issue. With a range of 10 to 20mm I decided this lens would offer very wide shots and near fish-eye creativity capabilities.I always buy only Canon lenses, but I don't buy the professional level models. After all, I am a photo hobbyist, not a professional photographer. Well even though I really wanted to purchase a quality ultra-wide angle lens, I was low on funds due to recently over spending on Christmas gifts for my friends and family. Although I wanted to buy a Canon ultra-wide, I just didn't have that kind of cash. I read several rave reviews on this Sigma 10-20mm lens so I ordered one up. I haven't had it very long but I have taken several photos...

Canon also has an EF-S 10-22mm f/3.5-4.5 USM lens. However the price is more than $700. Here is a Sigma, 10-20mm f/4-5.6 EX DC HSM. Sure it's little bit dark than Canon, but it's OK. Usally ultra-wide lens are used at outdoor. The photo is very sharp image and you can take a shot without cropping. And minimum focusing distance if 9.4" (24cm), you can make fun photos! Sigma also provice lens hood and carring case for free! |
