Hi, All:

While traveling with the normally stellar 50 1.4 and my K-1, the autofocus has suddenly failed. When I mount the lens, I get the manual SR focal length input screen, which quickly disappears (this is new). Then, the display screen reads “MF” regardless of the AF/MF switch positions on the lens and body. I’ve tried my other lenses; AF Is fine. Wiped off the 50’s contacts; no dice. This seems extremely odd for a Les that’s just a couple months old. Any thoughts? Hoping to use it for portrait sessions on the trip, and a little bummed.

I'm sorry to hear about that.

This looks like a communication, or electronic issue. If you can, try the lens on another camera just to confirm.

But only a trip to the service can fix it.
