I received my first legacy lenses in the mail today.
I found threads on this site instructing me how to get the G1 MF Assist zoom function to work with legacy lenses. I also read discussions of why it couldn't be made automatic.
Since most of the threads were from 2009 I will ask anew if anyone has discovered a better way. Currently I press the Left arrow button and then press the center button. That works but I don't like it.
PS: I don't blame Panasonic. I like the G1 and I am grateful they produced it.
