I just acquired an RTS II as a second body to my Aria. Everything seems OK with the camera except one odd problem. When, for ex&le, I mount my 85 mm f2.8 MM lens on the RTS II the aperture readout in the viewfinder says the maximum aperture is 2.0 instead of 2.8 when I have lens set at its maximum opening. When I move the lens to the f4 setting, the readout says its f2.8, and so on. I have two other MM lenses and I get the same readout: one full stop wider than the actual manually set aperture of the lens. However, with my 50mm f1.4 MM the aperture readouts coincide with the actual setting. Any ideas on what is happening? I assume the camera was made when only AE lenses were available; shouldn't the camera couple with and indicate the correct aperture in the viewfinder for MM lenses? Since I can return the camera if I find it to be defective, is this a problem I should be concerned about? In other words, are the electronic circuits of this camera broken? Thanks for any ideas on this.
