Originally posted by oculus Apparently M-series lenses cannot be used with K-500, K-30, and K-50. Here is what Ricoh Imaging Support told me:
Using Older Lenses on a K-500, K-50, K-30
When using a lens without an "A" setting on the aperture ring (M-series, or screwmount with adapter), these (K-30, K-50 and K-500) cameras do not display the exposure scale in Manual exposure mode and the Green button cannot be configured to do a Tv shift. A-series or later lenses can be used in all exposure modes on the K-30, K-50 and K-500.

...and your camera manual tells you something similar. That being that:
- K-mount lenses without the "A" contacts offer a limited set of functionality on your camera
- You cannot control the aperture from the camera body
- You must use M mode only with no exposure automation features. This includes auto-iso* and other similar wizardry.
- Stop-down metering is available using the green button
Translation? Your camera will behave in much the same way as the Pentax Spotmatic of 45 years ago.
That is not a bad thing. Think of it as the entry ticket into the realities of another age of photography.

* Too bad that Pentax did not continue the behavior of earlier models and have auto-iso disabled in M mode.
