I don't take sharp hb photos anyway so I can't blame that on the TC! My photos only get posted to the web and I pretty much never get any of them printed so I think a 2x produces pretty good detail for that anyway.
So, I ordered a used Kenko 2x tonight. It only gets me 300mm but every little bit will help!
