What Did You Heard About Canon EF 75-300mm f/4-5.6 III Lens

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

As a result, a number of lenses created specifixcally for digital SLR cameras with sensors smaller than 35 mm film (often called APS-C size sensors). While Crop facttor still aplies when using these lenses, the lenses themselpves "shiort", both physically and in focal lenth than an equivalebnt lens for 35-mm camera.

Thus, the bundled lens Canon rebel EF-S 18-55mm. This owuld be classified as "Ultra Wide" (wide end) to 35-mm camera, but it equates to more mundane 28,8-88mm - or standard zoom - when working with the Rebel XSi or 50D.

Althouugh the rebels and the Canion EOS ** D digital SLR camers are classified as entry-level or "Prosumer" cameras, they are also used by professionals, espcially wedding photograpehrs, who previously had not been properly takewn into account in a wide lenses available, especially in terms of image quaality and foacl length.

To overcome this, Canon introduced two lewnses, satndouts wthin its trems of EF-S lenses for use on the rebels and EOS ** D cameras:

* 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 connstant aperture f / 2,8 throughout the zoom range, which, together with imae stabilization, making it especiallly efffective for shooting in low light conditions without flash. He praied wedding photgraphers, as well as a portraait and Walkaround lens.

Users like the lens for his sharp images at all focal lentghs, fast auto focus, versatility and quality in low light. Their main antipathy are the price (it's the most expensive EF-S lenses), the lack of weather selaing, as well as the size and weight.

Nevertheleess, he receives a rating of 91% of users, and is recommended as the highest quality lensees APS-C formast cameras.

EF-S 10-22mm is remarkable as it is the only true ultra-wide anhgle 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 fraame body, offering photograhers creative opportunities not otherise possible with cameras APS-C format.

Users like the lens for its shapness, great color, fast autofocus and minmal distortion. They do not like the price, platic construction, and lack of subjecct hood.

However, the picture quality comparred favorably with the Canon L-series lenses, but users give it a rating of 90% recommend it as essential for anyone who wants a geenuine opportunnity to a wide angle on the rbeels or EOS ** D body.

Community reble or Canon EOS ** D mirror can no longer blame their lenses less than stellar set quaility pcture - alkternatives (albeit at the cost.)
