I think you misunderstood the purpose those "red" indicators (and I don't mean the infra-red index). On some old Pentax prime lenses, just match the red colour aperture and focus setting, and you can just shoot without further focus. It's more or less like a focus free P&S camera. regards, Alan Chan _________________________________________________________________ Chat with friends online, try MSN Messenger: http://messenger.msn.com - This message is from the Pentax-Discuss Mail List.
