Good buy

Anonymous, Newegg
4 October 2010
  • Summary: I'd say buy it. In order to get the reach that you are looking for it's either buying this for $300 or a lens $2000+. If you have the green and the need for perfection, then go buy a $6,000.00 dollar lens. Beggars cannot be choosers.
  • Pros: -Best way to extend your reach without breaking the bank. -Lightweight, easy to assemble -I AM HERE TO TESTIFY THAT YOU WILL NOT LOS ANY IMAGE QUALITY. I read and read, and then read some more. Whether it be outdoor football or wildlife, you will not be disappointed.
  • Cons: -You lose one f-stop, but as long as you are using it with the recommended lenses, it shouldn't be of any concern. -On my canon 70-200mm F/2.8 IS lens there is a slight increase in hunting during automatic focus. It, however, hasn't bothered me up as of yet.

  • Summary: I use this on my 200L and 400L. In terms of real world photography, IQ across most of the frame is quite comparable to the bare lens once you are a stop down from wide open. If you pixel-peep at 100% you will see a slight loss of contrast and resolution - moreso on the 400L than the 200L.
  • Pros: Good build quality. Not much impact on IQ or focus speeds with good primes.
  • Cons: Probably a bit over-priced, but definitely cheaper than buying a longer lens...

A must have...

  • Summary: The perfect accessory to the 70-200mm f2.8L and the larger Super Telephoto lenses. This is part of my standard baseball kit along with the 1D Mark III and 70-200 f2.8L.
  • Pros: Super sharp with no reduction in auto focus capabilities.
  • Cons: You lose 1 stop but it's cheaper than buying another lens!

  • Summary: I already have the 2x extender and bought this one on impulse after hearing good things about it. I thought I would keep this and sell the 2x extender but now I am not so sure. Most people are under the impression that the 1.4x extender is far superior to the 2x.
  • Pros: Build quality, Optical quality, Water and dust resistance, Excellent resale value, Stackable with 2x extender, The best extender money can buy but not a substitute for a longer lens.
  • Cons: Even though it is top quality I still feel the price is just a tad steep

  • Summary: Purchased with to go with 70-200 f2.8 (on my 10D) to shoot wildlife. Gives me excellent 'reach' in a relatively light, compact package and minimal loss of quality from an excellent lens. A monopod, at a minimum, is required for sharp images in most situations due to weight and magnification
  • Pros: very minimal loss of image quality, light & compact
  • Cons: not inexpensive

  • Summary: Optical quality is up to par with its previous counterpart. AF speed is undiminished-much better than the previous version.
  • Pros: AF speed of attached L lenses is essentially unaffected. Razor sharp photos.
  • Cons: none

Canon 1.4 mark II Extender

RGJ, Amazon
20 January 2015
  • Summary: This is an excellent addition to supplement Canon's compatible L lenses. It enables those of us who don't own the high-end Canon super lenses to achieve good quality extra reach. Some of the more recent Canon cameras feature quality, low noise, high ISO performance and this means that the loss of an...
