anyone use the 500mm Sigma 7.2?
I got ahold of this lense for I think a good deal. It's in great condition. Sure it's limiting with the slow F-stop, but in good light, it seems fine. A 500mm APO (AF)lense with collar, all for less than $300 on ebay.
Also, anyone here use a 1.4 teleconverter on one? Comments?
