Dan, The TC-14E will not physically mount to the 300/4 or any other non-AFS/AFI lens. However, the pin which interferes with mounting can be removed/filed off. I am curious to do the same, but do not relish spending $450 US to find out that the optical combo does not work well.

[v04.n239/2] Message: 2 Can I use a TC14E converter on my AF 300/4? I know AF won't work (it won't with the TC14B either!), but the stop-down mechanism should be ok, right? Or is there some physical or optical (vignetting / light fall-off) limitation? It would be nice to carry around just one TC for most of my lenses... (lucky Canon users)
