Tamron SP AF 17-50mm F/2.8 XR Di II LD Aspherical [IF] Lens for Canon

The FR AF 17-50MM F/2,8 XR Di II is light, compact and has a bright standard zoom lens, which meets high claims of quality It belongs to the SP (super performance) series and is particularly designed for digital cameras with sensors to 16x24 mm.
The focal length is comparable with 26-78 mm after conversion into similar values. The wide angles for focal length with 17mm (equivalent 26mm) make possible a picture angle as with the usual standard lens even when the design remains light and compact. In addition the large luminous intensity of F/2,8 makes possible attractive recording of Portrait even with a natural blurred background. As a result of a close adjustment border of 27 cm over the entire focal length range a maximum scale of 01:04.5 arises in the case of 50mm.
