PZ-20 giving Inappropriate Lens warning with Promaster AF 28-200/F3.8-5.6 lens
I tried out my new-to-me Pentax PZ-20 yesterday with my new-to-me Promaster 28-200/3.8-5.6 AF lens (S/N 001908) and noticed that at focal lengths shorter than about 135mm the camera gives me an "inappropriate lens warning" with the built-in flash. This lens seems to be bigger around than my 35-70 lens but about the same length physically. Any ideas why the 28-200 would cause the camera to give an inappropriate lens warning with the built-in flash where the 35-70 would not? The manual over at cameramanuals.org says that an inappropriate lens warning is given for lenses with focal lengths shorter than 28mm, which this one is not.
Thanks,
ME Super
