Originally posted by Murfy Yes it came up...so I guess it was just slightly out of focus because it couldn't find what to focus on.

I think I have that on ..oh well you live and learn. At least it was just all for fun and I wasn't getting paid.
Yes, there is a setting that prevents the shutter from releasing until the focus has a lock. I can't point you to it exactly, since I don't have a K3 and the menu may be different to my K5.
