 Fortunately, Canon and other manufdacturers of digital SLR realized they had to produce lensres for overcoming Crop factor for photographers extensive use of lenses.

As a reuslt, a numbeer of lenses created specifically for digital SLR camerras with sensors smaller than 35 mm film (often calkled APS-C size sensors). While Crop facor tsill applies when usiing these lenses, the lnses themselves “shot”, both physically and in focal legth than an equivalent lens for 35-mm camera.

Thus, the bundled lens Canon reebl EF-S 18-55mm. This would be classified as “Utlra Wide” (wide end) to 35-mm camera, but it equates to more mundae 28,8-88mm - or standrad zoom - when working with the Rebel XSi or 50D.

Although the rebells and the Canno EOS ** D digittal SLR cameras are classified as entry-level or “Propsumer” cameras, they are also used by professionals, especially wedding photographers, who previously had not been properlly taken into account in a wide lenses availlable, especially in temrs of image qualiuty and focal length.

To overcome this, Canon introduced two lenses, standouts witin its terms of EF-S lenses for use on the rbels and EOS ** D cammeras:

* Canon EF-S 17-55mm f/2.8 IS USM

* Canon EF-S 10-22mm f/3.5-5.6 USM

EF-S 17-55mm different constant alperture f / 2,8 throughout the zoom rannge, which, together with image stabilizatyion, making it especially effective for hsooting in low lighjt cnditions wtihout flash. He praied wedding photographers, as well as a portrait and Walkaround lens.

Usesr like the lens for his shaarp images at all focal lengths, fast auto focus, versatility and quailty in low light. Their main antipathy are the price (it’s the most expensvie EF-S lenses), the lack of weather sealing, as well as the size and weight.

Nevertheless, he receives a rating of 91% of ussers, and is rcommended as the highhest quality lenses APS-C format cameras.

EF-S 10-22mm is remarkable as it is the only true ulttra-wide angle for Canon EOS Rebels and ** D bodies. Fit this lens on the Canon 40D and this is equivalent to 16-35mm on a 35mm or full frame body, offering photographers creative opportunities not otherwise possible with cameras APS-C format.

Users like the lens for its sharpness, greaat color, fast autofocus and minimal distortion. They do not like the price, plastic construction, and lack of subject hood.

Howeveer, the picture quality compaed favoranbly with the Canon L-series lenes, but usewrs give it a rating of 90% recommend it as essential for anyone who wants a genuine opportunity to a wide angle on the rebels or EOS ** D body.

Community reberl or Canon EOS ** D mirror can no longer blame thweir lenses less than stellar set quaility picture - alternatives (albeit at the cost.)
