Thanks, Bruce. I need to reconstruct my experience with manual lenses, primarily A lenses, and mostly on a *ist DS. What I did was something like what you describe, but I don’t think I punched the green button. It was a button up in the top right corner of the back, right behind the LCD status screen is, and where the AE-L button is on the K-5. Could it have been the AE-L button? ------------------------------------------------------------------------------------------ Eric Weir Decatur, GA USA eew...@bellsouth.net "Our world is a human world." - Hilary Putnam -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
