A reasonable compromise....

Wrw627, Adorama

  • Excerpt: This lens represents a good compromise between the much larger / heavier 16-35 zoom and the 24-70 f2.8L lens I use most oft he time. It's not particularly sharp, has plenty of spher aberrations, but it's affordable and much easier to carry around. I bought it for the 17mm end of the range but it's more useful up closer to 25-30mm. The buyer shouldn't have remorse that they didn't buy the wider heavier 16-35 as it's about twice the price.
  • Pros: Durable, Lightweight
  • Cons: Chromatic aberration, Soft

Strong Build, Iffy Image Quality

  • Excerpt: First, the good news. This lens is built like a tank. That is not to say that it is heavy, but rather it is built to last. The lens has a sturdy feel to it and, let's face it, it looks really good mounted on your camera body! However, there is some bad news. Although the build quality is what one would expect from a Canon L-series lens, the image quality is not.
  • Pros: Durable, Easily Interchangeable, Fast / accurate auto-focus, Rugged, Strong Construction
  • Cons: Blurry Focus, Chromatic aberration

verdict out

  • Excerpt: Am not sure I like this lens. It is plastic and does not have the typical L lens feel. Guess you get what you pay for. Have taken some okay shots but have not put this lens to the test yet, that's why the average rating

Filter tread allow you to use several filter,also good the possibility to use the rear gelatin filter holder.Most people consider f4 is not bright enought but for daylight pictures and night shot with tripod is excellent,also good in backlit,really few flare.

Scratchy Zoom Ring

Alex, B&H Photo

  • Excerpt: This lens is very sharp in the center but not so much in the corners. Need to stop down to f11 to get the corners sharp. I was a little disappointed with a scratchy zoom ring. This was my first L and maybe my expectations were a little high. Either way, this makes a great landscape and daytime walk around lens for me.
  • Pros: Consistent Output, Durable, Fast / accurate auto-focus, Lightweight, Rugged, Strong Construction
  • Cons: Difficult to Clean, Poor in Low Light

Good for candid shoots only

  • Excerpt: I tested this lens in variety of situations with very different results. I have only owned fixed lenses until recently; this it a first purchase of a zoom lens and most likely the last. It performed well when I used it in a studio and outside during candid photo-shoots, however when I tried to produce long exposure shots using ND grad filters during the day (with no wind, camera on a tripod) or when shooting at night (long exposure on a sturdy tripod with no wind again)...
  • Pros: Easily Interchangeable, Lightweight
  • Cons: Blurry Focus, Poor in Low Light, Slow Focus

Nice and wide on full frame

Phil, B&H Photo

  • Excerpt: I've just gotten started with it, but I'm using this lens on a 5DmkII. It's easily my widest lens, and is quite wide on the 5D. I've never used the 16-35 or the 14mm. While it's not exactly what I would call a cheap lens, it is cheap for an L lens, and so I would expect some compromises to have been made. While I've not done any sort of side by side comparison, I would say it's not the sharpest lens, particularly at the edges, and it does have some vignetting.
  • Pros: Compact, Relatively Inexpensive, Well built quality
  • Cons: Not sharp, Vignetting

Canon EF 17-40mm f/4L USM Ultra Wide Ang

rone, Adorama
2 September 2011
  • Excerpt: This is entry level L series lens. This lens is slightly better than the regular lens and I know of some non L lenses that are better. This lens is at its best on a crop sensor camera shooting in lots of light and on a tripod. Very soft when used on a full frame camera. I use this lens for close shooting and gives a nice, slight fish-eye effect.
  • Pros: Durable, Easily Interchangeable, Nice Bokeh
  • Cons: Blurry Focus, Poor in Low Light
