Customer Reviews on Canon 2x EF Extender III (Teleconverter)
Review by Maria Yordanova, 26/04/2011, Customer Rating:
PROS: As an amateur photographer I would say that is an excellent addition to my equipment. It's great for birds and wild photography at the National Wildlife Center. A must have if you like to take photos of moving object which don't always want to come close to you.
CONS: The quality of the pictures is slightly decreased, but the autofocus is 4 times slower and you'll probably notice it (the difference is significant).

Dear Sir, unfortunately I have returned the lens for a refund. This was nothing to do with the quality of the product but it just made my set up to heavy to hand hold without me shaking to much!! I have been unwell for some time and I had hoped I would have enough strength to hand hold my set up but unfortunately I am not able to. If at some point I buy a tripod then I will re purchase the extender as it will be extremely useful for my growing interest in wildlife photography. Sorry I could not write a proper review at this time. I would appreciate it if you could confirm that you've received the lens back for refund. Thank you
