Tim, Thanks for the useful info. I suspect I will use the TC with the AF lenses I have. I will have to try it with both my Sigma 70-200 F2.8 and APO 300 F4. The Penatx TC has to be better than the Sigma APO 1.4x TC I have.
Overall I have pretty good coverage in the telephoto range considering I have the slow but useful Sigma 170-500. Still I could not pass up the deal. Perry.
