Canon EF 17-40mm f/4L USM lens, (tested with cropped-frame APS-C body)

The Canon EF 17-40mm may deliver spectacular ultra-wide angle coverage when fitted to a full-frame body like the EOS 5D, but offers a more normal, general-purpose range when mounted on cropped bodies like the EOS 30D or 400D / XTi.
Pros:
  • Canon 'L' build and optical quality
  • Fast and quiet USM focusing motor
  • Constant f4 aperture throughout range
  • Will also work on full-frame body
Cons:
  • Shorter zoom range than kit lens
  • No IS (although not particularly necessary
  • Overkill if not considering full-frame in future
  • Canon EF-S 17-85mm more flexible for most

Canon EF 17-40mm f/4 USM L (full format) - Review / Test Report

It's not exactly easy to design a flawless full format lens and the Canon EF 17-40mm f/4 USM L shows its part of the struggles here. The lens is not overly fast but it has a comparatively broad range for a lens in this class and it seems as if Canon has overstretched things a little with respect to...

A Great lens for the money

A lovely lens for the price, very fast to focus and very quiet. I use it on a 600D body so only use the centre area of the lens. I suffer no curving on the edges as full frame sensors are reputed to suffer. As you would expect for a "L" series lens, it's built like a tank with weather sealing.
Pros:
  • Consistent Output
  • Easily Interchangeable
  • Quick Focus
  • Rugged
  • Sharp Focus
  • Strong Construction

Canon EF 17-40mm f/4L USM

I have recently used this lens for landscape and seascape images in mostly good outdoor light on two full-frame cameras, namely the EOS 5D and EOS 5D Mark III respectively. Although it covers a range of focal lengths I already had mostly covered by three prime lenses, I did not previously possess...
Pros:
  • Robust and impressive build quality with smooth handling
  • relatively lightweight
  • reliable autofocus
  • familiar vibrant Canon colours
  • Well priced (at least by 'L' standards)
Cons:
  • Very weak corner resolution at 17mm below f/11 on full-frame
  • The bulbous and ugly lens hood is large, obtrusive and awkward to pack unattached

Because it is a very high quality but moderately-priced ultra wide angle zoom lens, the Canon EF 17-40mm f/4L USM Lens is one of Canon's best selling lenses. The 17-40 f/4L fills out the bottom focal length range of Canon's f/4L zoom lens series .
