Here's a comparison I shot at 1/8th of a second: http://markcassino.com/b2evolution/media/sr_comp.jpg The top image has SR on. The comments regarding subject motion and other factors are also very true - you may be able to shoot at a slow shutter speed but if your subject isn't still, then the shot may still be blurry. But, it is a very valuable tool. - MCC -- - - - - - - - - - - - - - - - - - - - - Mark Cassino Photography Kalamazoo, Michigan www.markcassino.com - - - - - - - - - - - - - - - - - - - - -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
