Premium Members Alan Mehlbrech Posted November 23, 2011 Premium Members Report Share Posted November 23, 2011 Hey, I just did a test and it is not a focus motor. It was slow getting to the mark -BUT it is a wonderfully light iris motor. Alan Quote Link to comment Share on other sites More sharing options...
