  • Summary: Used on my 70-200 f4 IS and Canon 40D, this converter has given very good results. The trick is to use it with the 70-200 zoomed all the way out to 200. Used this way, the images are very sharp.
  • Pros: Lends flexibility to existing compatible lenses. Lighter than getting a dedicated long telephoto lens, great image quality.
  • Cons: Image quality degrades when lens is not at full telephoto - no zooming. Pricey!

  • Summary: Used with 'L' series primes this convertor works fantastically well, IQ and sharpness lose nothing from the standard lens. > A no brainer - just buy one if you use 'L' series primes > Doesn't work well with 'Hell' ZOOMs but hey Zooms are for snappers only, this convertor merely magnifies their...
  • Pros: Killer piece of kit for use with 'L' primes - You must have one
  • Cons: None whatsoever

  • 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: I have this TC mated to my 100-400L. There's nothing to complain at all here! The build is as solid as the best L lenses, it includes a weather sealing O-ring, and the image degradation is minimal.
  • Pros: Weather sealing, solid construction
  • Cons: Pricier than competition

  • Summary: Modest impact on image quality over the naked lens, especially for primes. My experience is generally that lens magnification of any type produces better results than enlarging in post processing.
  • Pros: minimal loss of image qualilty
  • Cons: none for what it is

  • Summary: I bought to use with my 100-400L. It is a high quality piece of glass but does noticebly degrade the image on that lens. I have used it on my 180mm macro with better results. I understand that it even works better with Canon super teles but have not tried it myself.
  • Pros: Cons:

Canon 1.4X Extender EF II review by terryf

  • Summary: Well over half of the images that I capture with my 300mm L f4 IS lens are made with the 1.4x Extender mounted. Any loss of image quality is very minimal. It is important to note that both AF and IS are maintained when I use this combination on my 20D.
  • Pros: Greater reach with minimal loss of image quality.
  • Cons: None
