Hello all,
sorry for taking so long to react.
I can't seem to find time to devote to photography:-(
I decided to not use any of the older lenses until I can properly assess them. I was fortunate enough to have the camera repaired in warranty, so all went well.
Thank you all for your comments.

That being said, it is possible to munge the aperture actuator by mounting a defective lens. I know...I've done it...with a new lens fresh from the (not Pentax) factory. That is why I always do a thorough inspection of all lenses I purchase (both new and used) to check for any obvious damage and/or fault in construction.

I am not sure that if this is a knows issue that it would only affect the K-30 and 50. I specifically asked the serviceman if the aperture mechanism on this midrange Pentax is any weaker than that of the higher models. He mentioned that they share the same mechanism...
