Hi - anyone else struggled to work out why in All modes, the K7 won't let me use my SMC FA 50mm f1.4, and just flashes at me F--- on the screen and top display. Presumably it wants me to tell it what f stop I'd like but I'm totally stumped on how to do that, nothing I try seems to make it happy, and so I can't seem to use the lens with my new K7! Help!

put f-stop on A(auto) on your lens, then you can manually change it

Make sure the aperture ring of the lens is on the "A" setting. You need to press the corresponding button on the lens to get it there.
