I would disagree with Josh. You can't compare 17-40mm lens to 14-24mm lens and rate them. You are comparing apples and oranges. 17-40mm L is a great glass for its value.

  • L Lens at an Affordable Price

  • April 14, 2011
  • By: Matthew

The 17-40mm L is an amazing piece of glass. I use this lens on my 7D so I don't get the full capability of its width on the cropped sensor, which one would on full frame. But even mounted on a crop, it still gives a very wide field of view. The build quality of this lens is exactly what you'd expect of an L series. It feels strong, and has a good weight to it. There isn't any play in the rings, and it has a metal mount. And of course, it has that nice red ring. This lens produce fantastic image quality. With a max aperture of f/4.0, you aren't going to get shallow DOF but that isn't really the purpose of this lens anyway. Between f/8 and f/11 is where is lens shines with amazing sharpness, edge to edge. An indication of what this lens is intended for; landscape photography. I can't say enough about how good this lens is. A lens with this level of quality, and the L moniker at such a good price; you can't go wrong. If you enjoy landscape photography this lens will not disappoint.

  • Great glass for a great price.

  • May 25, 2014
  • By: Nick

The 17-40 f4L is my first L series lens and I've been more than happy with it's performance over the past month (shooting with 60D). For the money you're getting a great focal range making this a very versatile lens. I've found applications for it in everything from landscape to street. With it's wider end being 17 I'd probably avoid portrait because of the distortion but that's to be expected I think from this type of lens. Considering the highest f-stop is 4.0 the bokeh is pretty reasonable. Vignetting is noticeable when at it's widest but disappears when brought in to 40mm. The build quality is amazing as well and the focus, and zoom rings are really smooth. This being my first I thought it was a big deal! Also if you add a filter it is water sealed assuming your body is as well. TL;DR Amazingly versatile and strong piece of glass for the price. A great introduction to the L series.

  • Amazing piece of glass

Pros: ? Cheapest L series lens on the market ? Reasonably fast (F4) ? Sharpest of Canon's Ultrawide Angle lenses (Q3, 2011) ? 77mm Diameter ? Distance/Focus gauge ? Excellent Build Quality ? Excellent Image Quality Cons ? Not quite as wide as Nikons flagship 14-24mm ? Lose one stop of light vs the 16-35mm ? Corners are poor quality @ 17mm on Full Frame ? Aberration needs heavy correction. Overall this is a fantastic lens, and if you don't find yourself needing a wide angle full time, but still want that focal range, this one for sure. It is SHARPER than the 16-35, however if you are using a wide angle often, look into a F to EF adapter and get the Nikon 14-24. Best wide angle on the market.
