erratic sharpness

Magic Marker, B&H Photo
23 December 2012
  • Excerpt: I found that getting the auto focus to "lock on" was erratic. Most images were soft. I did micro adjust the focus on my 5D Mark II which gave a slight improvement, but the auto focus was still erratic. Some images sharper, most still soft.
  • Pros: Durable, Strong Construction
  • Cons: Blurry Focus, Poor in Low Light, Slow Focus

waste of money

Agugslp, Canon

  • Conclusion: Started out ok, but after a few months this lense turned out to be a waste of money. Images not sharp, very slow. Not worth the money. It's been in for service several times. Image stabilizer burnt out twice. I think I received a lemon.
  • Cons: Slow auto-focus, Semi-sharp images, Poor build quality

Disappointed

Beancounter, Canon
28 March 2012
  • Conclusion: This lens was purchased to capture wildlife. I too agree with the review by lorendn on 3/3/12 and have the same result. I'm very disappointed with the sharpness and wondering if I should send the lens back to Canon for repair or replacement. I am very pleased with other Canon lens that I have.

Not up to par

lorendn, Canon
3 March 2012
  • Conclusion: I purchased the 100-400 f4.5-5.6L about 2 months ago and have never been satisfied with its sharpness. I have 4 other EOS L lenses and am constantly amazed at the quality of the images I capture with my 7D. This lens totally misses the mark and its performance is disappointing. The images are excessively soft and lack the sharpness of other L lenses. It is almost unusable at f4.5-5.6 and barely acceptable under ideal circumstances at f8-16.
  • Pros: size weight, cost
  • Cons: image quality, is system is weak

Problems with this lens within 3 months

  • Excerpt: Within 3 months of using this lens, the switch for the image stabilizer was missing. Canon denied covered on their warranty (impact). I was told that both Canon and Nikon are turning down nearly all claims after the earthquake. I recommend additional coverage to cover expensive repair costs. Have quality fallen after the earthquake too?

  • Summary: I studied many reviews on this lens and waited over a year before finally purchasing it. Walmart had it at a fair price with a good return policy, and the shipping cost was reasonable. I knew the lens has some limitations, but I really thought it would work for me. I shoot with a crop format 40D, and wanted this mostly for general wildlife use. Sometimes on a tripod, often not.

Left me hanging

Paul, B&H Photo
9 October 2010
  • Excerpt: I loved this lens, but now it has fallen victim to what I read about and hoped wouldn't happen to mine. The bearings on the inside have come loose, the IS has stopped working because of it, and now at a very busy part of my year, I have to send it off to get repaired. (so more $ for a lens I already payed [$] for) OUCH!!!
  • Cons: Heavy, Lens Creep, Weak Casing

Disappointed For the Price

Samson, B&H Photo
8 July 2010
  • Excerpt: As a professional, I usually shoot landscapes but I have recently started to get more into wildlife. After much research, I pulled the trigger and bought this. Right out of the box the lens feels well built and heavy. I was surprised at the size of the lens. It is smaller then the 70-200mm f/2.8 when zoomed out and only looks truely impressive in size with the lens cap on.
  • Pros: Rugged
  • Cons: Blurry Focus, Lens Creep, Not sharp, Poor in Low Light

  • Conclusion: A complete waste of money:- Soft Awful Bokeh Terrible zoom action, reminds me of some awful 1970's zooms I once owned. A dust Pump A disgrace to Canon's Famous 'L' lens series > Just avoid the temptation to buy one - get a 400 F5.6 'L' and a 135 F2 'L' instead > Only plus point I sold mine for a good price on ebay, check ebay out there's plenty of this lens for sale, so obviously other owners don't like 'em either.
  • Pros: None
  • Cons: A truly awful lens - soft - difficult to use the push/pull system - but worst of all the things an air pump - dusty dusty 'Dusty Bin' it ought to be called - did I mention the lack of IQ and the soft focus images - the worst Canon lens I've ever owned - though the 70-200F2.8 IS comes a close 2nd.
