With an effective focal length range of approximately 16-35mm in 35mm format, this lens allows you to get extremely close to subjects, exaggerating the difference in size between a near object and its background. Creative photographers can use this phenomenon to create excellent separation between subject and background for a strong sense of presence, or for a pan-focus effect with everything from foreground to background sharply in focus.
Designed specifically for digital photography, the lens has specially shaped lens elements and Super Spectra coatings to suppress ghosting and flare, which can be caused by reflections off digital camera sensors. An exclusive optional lens hood can further reduce the incidence of flare.
Please Make Note: Not suitable for 35mm film SLR cameras, or for 35mm size "full-frame" digital cameras, e.g. 1Ds or Kodak Pro SLR/c
Not suitable for 35mm film SLR cameras or digital camera with image sensor bigger than APS-C size, only fits on the EOS Digital Rebel series or 20D, 30D, 40D and 50D, 7D SLR cameras.
