Pentax K-50 manual lens no longer asks focal length?

I got a bunch of old manual lenses for my Pentax K-50. Initially I thought they didn't work, but that's because I never initiated the 'C4, 22. Using Aperature Ring' and setting to Enable.

Thing is, I recall (when u switch the camera on) that it asked for Focal Length, 24mm, 50mm etc, but it no longer does this step at all, why has it stopped? I interchange 24 and 50mm lenses all the time and it just works, but because this Focal Length step is now omitted I am concerned I am not effectively using the lenses.

Anyone know what's going on?

That means shake reduction has been turned off

Or the camera is in a shooting mode that turns it off automatically.

Yes, shake reduction was off, thank you, that fixed it

However, I'd been going quite sometime without setting the focal length, didn't seem to matter much (or did it?), what's the deal?

The camera only uses the set focal length for SR calculations and EXIF data. IF SR is off, your EXIF is wrong for some of your shots. If your hands are steady and/or the shutter speed is reasonable, you don't need SR's help.
