I own a canon 400 f5.6. I want to upgrade to a longer lens but, the new prices are way out of my price range. I use the 400 with the 1.4 teleconverter II and I get acceptable results in spite of having to focus manually (50d). Has anyone tried the 400 5.6 with the new 2x teleconverter? I know that the usable f stops will be limited. Is there any chance that I will get a sharp picture? I know that I am asking for a lot but at least it's within my budget. I would appreciate any thoughts or experiences that would help me make a decision. Thank you.
I used to get sharp images with the 2xII and the 100-400mm, but only under ideal conditions. I don't think its a reliable enough combination to be productive. You are likely better off saving youir money for one of the bigger lenses.
It is possible to get decent shots with this combination. I've used it with a 1DsII. But don't kid yourself--focussing is difficult, you need a STABLE head and tripod, and good light. I only try it when I'm desperate. One problem is my tripod: it's not meant to carry an effective 800mm lens. Note that I said it's possible, not practical.
Canon 400 f5.6 + 2x teleconverter III ???
