Originally posted by stormtech I think I am going nuts - going full circle after buying then selling a 60B 300 2.8 - now I am thinking of starting over again.
I tried that combination with my 360B hoping there might be some usable autofocus functionality in the pairing. I didn't find it that effective as an AF-capable lens (although it worked fine) and resolution wasn't any better than with either the Pz_AF 1.4x or the 140F TCs. For the price involved, and given that both 1.4's were in hand, I re-sold the AF 1.7 and haven't regretted it (especially since that financed the SP AF 24-135 and SP AF 17-35 which have proven MUCH more useful).
Here's the 360B at ISO 800 plus the Pz-AF 1.4x plus cropped to about 1/3 original image size and 'squzzed -down' for up-loading.
