This thread inspired me to try something a bit silly. I put my vivitar 2x macro teleconverter on my bigma to see how close I could get. In terms of image quality, the experiment was not a resounding success, but if I ever need to do macro photography from eight feet away, I guess it would be handy to have a 1000mm macro lens. -- Larry Colen [email protected] sent from i4est -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
