I haven't used the 40-150 in a little while, and the EM1 works fine, focusing AF, with other lenses.

But when I put on the 40-150, it doesn't autofocus and the front panel keeps showing MF.

What could be causing this?

is the manual clutch engaged?

Yes, it was.

I'm an idiot. I hadn't used it in a while, and was used to seeing an AF/MF switch on a Panasonic. Once I moved the clutch, yes it worked.

Thanks!

Not an idiot. I do it all the time during weddings. The ring gets moved and in the heat of the moment I forget why it won't focus. Since I only use back button focus I never need an mf switch. On all my canon and Panasonic lenses the switch is taped down on AF. You can't do that with the 40-150. It the only thing that keeps it from being perfect.
