Hello,

I am thinking about purchasing a 1.4x teleconverter to put on my 70-200mm F2.8 IS. While I cant justify buying the 100-400mm, I can justify buying the teleconverter. I am just wondering how the images quality suffers from the use of the 1.4x teleconverter.

I am planning on using this on two bodies, 40D and 5D Mk II. Is anyone using this combination? Are you happy with the results?

Cheers
-Nigel
