"So, how does an incompatible EF500 Firmware load function (or not) on the K10D? I just put my 2-year old flash on my brand spanking new K10D, fired, and the shot looked ok."
Should not have. Mine was about 1 year old when I sent it back to Sigma about 6 months ago. It would do nothing, even on manual (flash) no matter how I set the camera. If it indeed works in the auto and program modes count yourself lucky!!! Walt -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
