I've got the Zuiko 1.4 teleconverter, and only have used it on the
50-200. I'm not overly impressed with IQ, but then I have been able
to snag a few images I might otherwise have missed. If you're not
printing big, the loss of IQ shouldn't be overly noticeable. I
noticed the IQ improved somewhat with the E-510 and image
stabilization, so maybe my IQ woes were of my own making.
