[QUOTE="STM, post: 562924, member: 12827"] I have both a TC-14B and TC-300 and they both worth very well with my 300mm f/2.8 and 600mm f/4. In fact I see no degredation whatsoever with the TC-14B, just a tiny amount of CA. Just for grins I once stacked both of them on my 600mm and the IQ went to hell in a handbasket pretty quickly. If I want that much magnification, I switch to the D300. [/QUOTE]
