For APS-C size image sensor cameras

Tamron SP AF 17-50mm f/2.8 XR Di II VC LD Aspherical (IF) for Canon is a high-speed wide-to-moderate-telephoto zoom lens designed for Canon DSLR cameras with smaller sensors. It cover the very popular 17-50mm focal length range (which is equivalent to 26-78mm in the full-frame 35mm format) making it extremely versatile. Tamron's Vibration Compensation (VC) mechanism minimizes the effects of handheld camera shake (up to 4-stops), providing a means to great low-light shooting. The lens delivers impressive sharpness and striking contrast over its entire focal length and aperture range. A maximum aperture of f/2.8 delivers images enhanced by shallow depth-of-field, and smooth, natural transitions in out-of-focus areas of the image.

This EF lens has been very useful for me, however I rarely ever use it anymore, thus the reason why I am selling it. It does have the beginning of mold forming inside, however this is extremely minute, please see the images to see what I mean. This does not affect the quality of the image or images shot whilst using it. There is also a lens filter that comes with the lens. This is a Rodenstock digital pro UV/1x filter.
