Using the Canon IS system all the time shortens battery life. Thus the switch, so you can turn it off when you don't need it. I would imagine in-body systems will also shorten battery life, but probably not as much. Bob -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net
