Does not live up to expectations
on February 22, 2017

I do not recommend this extender as it impacts sharpness. In numerous tests, this extender reduced the sharpness of my EF 70-200mm f/2.8L IS II USM from what I would describe as tack-sharp to "soft". There is no sense in having a 1.4 boost in focal length if the picture is not sharp.
No, I would not recommend this to a friend.

It appears to not be sharp at least at 4.0, 4.5, 5.0 and low apertures. Not surprised as I have had a few 1.4x extenders that have also proven to not be sharp. Very annoying...It may get sent back after I run a few more tests.

wrong tool

Auto focus will not work with Canon 70D and Canon100-400 f.4-f.56 - f stop loss is too much for it to handle. Would have been nice to know requirements before purchase. I have returned for refund.

Disapointed in Canon's product registration
on July 30, 2016
Posted by: Stevez
I love the product, but canonusa.com registration process does not even allow the user to view the serial number and purchase date information that one previously entered. This is very frustrating when doing things like providing information for insurance coverage or opening a support ticket. Fix the registration process, and I'll rate on just the product and raise it up a lot.
I would recommend this to a friend!

The distortion at long range is more than I thought it would be.
