The Canon EF 20mm f/2.8 USM is an ultra-wide-angle lens that lets you capture more in the frame by broadening the angle of view - great for group shots and landscape shots. Released for Canon's full-frame DSRLs in the 1992, this lens can be used with APS-C format DSRL as a wide-angle lens with 32mm equivalent focal length. It's constructed of 11 elements in 9 groups, and features floating system for sharp images with minimized aberrations at close focusing range. An Ultrasonic Motor (USM) provides fast and quiet autofocus action, while manual focus can be performed smoothly and accurately via the focus ring. Thanks to the rear focusing mechanism, the front of the lens does not rotate so you can use a polarizer easily. Plus, with a relative compact design and low weight of 405g, this lens is easy to hold and carry so beautiful scenes capturing can be effortless.

  • newegg Superb Optical Performance The lens features optical design of 11 elements in 9 groups, and features floating optical system that dynamically varies the gap between key lens elements based on focusing distance rather than using fixed spacing. Aberrations are effectively suppressed throughout the focusing range, assuring high image quality in all shooting situations.
  • newegg Ultrasonic Motor The Ultrasonic Motor delivers fast and quiet autofocus performance, which is particularly important to video recording using this lens.
  • newegg Full-Time Manual The full-time manual focusing enables the photographer to manually tweak focus without switching out of AF mode.
  • newegg Rear Focusing A rear focusing lens has the focusing lens group(s) behind the diaphragm, which allow for compact optical systems that produce faster AF. And because the front of the lens does not rotate to focus, filter orientation remains stationary for unaffected effect.

5 out of 5 eggsIncredibly Sharp

Pros: Sharpness, fast AF, color, contrast

Cons: None

Other Thoughts: Agree with the other reviewer RE crops. I'm using this on a trip and with a 7D @ 18MP I get fantastic 100% crops. This is a great landscape lens and I think a great buy if you can deal with primes.
