You can't set the aperture using the camera's thumbwheel to match the lens - it doesn't work. So you need EV compensation instead.

Maybe Pentax views this as a bug with the K-50 firmware - I don't know. Doesn't matter, I hope they haven't "fixed" it with a firmware update (I'll give you my camera's firmware details in due course).

Also, this may apply to cameras other than the K-50 (for example, K-30, K-500 etc. - I don't know - I hope so).

I believe that all Pentax cameras behave identically.

They certainly do NOT. Take a K2000, for example - it won't stop down with an M lens in Av mode. It'll take a nicely exposed shot wherever you set the aperture ring BUT TAKE A LOOK AT THE SHUTTER SPEED WHEN YOU SHOOT AT F22.

I'm rapidly getting fed up with these tedious interchanges. If you don't understand what I'm saying, try it for yourselves. I was only trying to help - perhaps some are beyond that.

O.K. I let you breath I didn't realize that the camera with the aperture ring enabled doesn't allow you to set the aperture value on the camera, in the Av mode for example, that the camera always assume a fully open lens. Then of course, only the EV compensation can help.
