Not what I've come to expect from an L

  • Excerpt: I must admit that I'm sadly disappointed with this lens. I also have a Canon 70-200mm L f/2.8 series which produces remarkably sharper images than this 100-400. The lens does a pretty good job, but it simply isn't as sharp as I've come to expect from a Canon L series lens.
  • Pros: Fast / accurate auto-focus
  • Cons: Blurry Focus, Heavy

  • Excerpt: It may be just I need to use the lens more. The push pull to get you distance is difficult to adjust too. The auto focus seems a bit slow./
  • Pros: Easily Interchangeable, Lightweight, Strong Construction
  • Cons: Poor in Low Light, Slow Focus

  • Excerpt: I bought this lens for wildlife, and used it for 3 weeks in Alaska. The zoom capability provides flexibility, but it does not produce tack-sharp images when wide open and at 400mm. I have tried both a tripod and 1/1000 shutter speeds, but was not pleased with the results.

OK for ameatures, but not ready for pros

  • Excerpt: I have been shooting with this lens for almost 4 years now. My biggest gripe with the lens is it's lack of sharpness out at 400mm. Since I also own a 70-200 f/2.8L USM, it was easy to compare images shot on the same body, and there is no comparison.
  • Pros: Consistent Output, Durable, Easily Interchangeable
  • Cons: Blurry Focus, Heavy, Lens Creep

  • Excerpt: I use this lens primarily for birding. It is very sharp for a zoom lens, but heavy if you do much walking. A vest harness makes this much easier. I've had mine for two years and, like other photographers I know, have a consistent problem with lens locking up at 200 mm mark. It will not budge!

Sharp, except for the 400mm range.

  • Excerpt: I was hoping to replace my 70-300 lens (a non-L lens) with this popular zoom lens, and to obtain enough reach for bird photography. Unfortunately, at the long, 400mm length, it was no sharper than my much smaller and cheaper 70-300 lens.
  • Pros: Easily Interchangeable, Rugged, Strong Construction
