(More customer reviews)I acquired this lens to provide me with an ultra-wide zoom for landscapes and indoors uses. I do not routinely shoot in this focal length range, so I was hesitant about spending so much on the Canon 10-22mm, although the Canon 10-22mm is by all accounts, fantastic. I have had very positive experiences with Tamron in the past, and decided to give this lens a try over the Sigma equivalent. Cosmetically, the lens is very lightweight but feels solid in the hands, and the zoom ring takes some getting used to as it rotates in the opposite direction as Canon brand lenses. The finish on the lens is very nice and the included lens hood fits nicely, but provides only minimal protection to the front element. This is understandable since this lens is an ultra-wide zoom, and larger lens hoods would cause vignetting and shadowing problems. The lens hood does a nice job of protecting from lens flare issues. The lens extends only a small amount when zooming. Performance wise, the lens is quite soft wide open, which is somewhat disappointing but not a major issue for my own uses. It is something to be acutely aware of nonetheless. However, stopped down to f/8 or narrower fixes this problem, and at f/8 and narrower, the lens is very sharp with very nice color contrast and saturation. Sharpness falls off again at f/16 due to diffraction, but between f/8 and f/16, the lens is excellent. CA is nicely controlled as is barrel distortion, both of which are common big problems for many lenses in this focal range. I was pleasantly surprised with this lens's control of CA as I was expecting it to be much worse than it is. I borrowed a friend's Tamron 11-18mm lens, and my 10-24 was VASTLY superior with regards to problems with CA and barrel distortion and adds a complete stop of speed. The upgrades that Tamron has made with this lens are very noticeable and worth the extra cost over the previous generation Tamron ultra-wide zoom lens. The autofocusing is very quiet, accurate, and fast. Overall, this is a very nice alternative to the vastly more expensive camera-branded lenses like the Canon 10-22mm or the extremely expensive Nikon super-wide angle lenses and provides very good quality in this zoom range.
UPDATE: Recently, this lens took a serious tumble from about 3 feet off the ground onto a hard tile floor. The only damage was a ding on the lens cap! I'm impressed.

Tamron AF 10-24mm f/3.5-4.5 SP Di II LD Aspherical (IF) Lens for Canon Digital SLR CamerasThe ultimate extended-range, ultra-wide-angle zoom lens! Wider and longer than others in its class, this compact, lightweight,high-performance lens for DSLRs with APS-C size sensors provides 35mm equivalent coverage from 16mm ultra-wide to 37mm semiwide,a remarkable 2.4X zoom ratio. With a maximum coverage of over 108°, this state-of-the-art classic is the perfect solution forexpanding your visual horizons.This ultra wide-angle zoom lens for digital SLR cameras, with the first-ever focal length range of 10-24mm-the 35mm equivalent of 16mm ultra wide-angle to 37mm semi-wide-angle-is a perfect tool for creating dramatic landscape, cityscape,a nd seascape imagery. At the ultra wide-angle setting, you'll be able to capture vistas beyond what the eye can see. At the semi-wide-angle setting, you'll capture scenes with angles of view almost as spectacular.SP AF10-24mm F/3.5-4.5 Di II FeaturesDi IILenses are designed for exclusive use on digital cameras with smaller-size imagers and inherit all of the benefits of our Di products. These lenses are not designed for conventional cameras and digital cameras with image sensors larger than 24mm x 16mm.Super Performance (SP) for Discriminating ShootersTamron SP (Super Performance) series is a line of ultra-high-performance lenses designed and manufactured to the exacting specifications demanded by professionals and others who require the highest possible image quality. In creating SP lenses Tamron\'s optical designers put their foremost priority on achieving superior performance parameters—they are all designed to a higher standard with little regard for cost constraints. As a result, Tamron lenses bearing the SP designation feature impressive and innovative designs that have established an enviable reputation for excellence among those knowledgeable photographers that demand the very best.Internal Focus (IF)Internal focusing (IF) provides numerous practical benefits to photographers including a non-rotating front filter ring that facilitates the positioning of polarizing and graduated filters, and more predictable handling because the lens length does not change during focusing. Even more important, Tamron's Internal Focusing (IF) system provides a much closer minimum focusing distance (MFD) throughout its entire focusing range. In addition, IF improves optical performance by minimizing illumination loss at the corners of the image field, and helps to suppress other aberrations that become more troublesome at different focusing positions.Low Dispersion (LD)Low dispersion (LD) glass elements in a lens help reduce chromatic aberration; the tendency of light of different colors to come to different points of focus at the image plane. Chromatic aberration reduces the sharpness of an image, but glass with an extremely lowdispersion index, has less of a tendency to separate (defract) a ray of light into a rainbow of colors. This characteristic allows the lens designer to effectively compensate for chromatic aberration at the center of the field (on axis), a particular problem at long focal lengths (the telephoto end of the zoom range), and for lateral chromatic aberration (towards the edges of the field) that often occurs at short focal lengths (the wide-angle end of the zoom range.)Aspherical Elements (ASL) Provide the Ultimate in Image Quality and Compactness)Tamron uses several hybrid aspherical lens elements in many lenses bearing the Aspherical designation. These innovative optics allow us to achieve the ultimate in image quality, and at the same time produce lenses that offer remarkable zoom ranges in extraordinarily compact packages. By perfecting theses cutting-edge advances for series production, Tamron has advanced the state of optical design, and virtually eliminated spherical aberration and image distortion from the high-power-zoom series.Through the effective application of Hybrid Aspherical Technology, one lens elemen tcan take the place of multiple elements without compromising performance. This is what allows us to produce remarkably compact long-range lenses that deliver a uniformly high level of image quality at all focal lengths and apertures.
