I've got a D600 with a high number of activations. I shoot 100-125 bracketed shots on a typical day. This past week I've noticed that the f-stop occasionally switches to zero (0) and I can't change it. I shoot in aperture priority mode.
Does anyone have an idea as to why this is occurring? I've read that it might be due to dirty connection points on the lens mount but I haven't removed the lens from this camera in over a month. Any thoughts or suggestons?

It sounds as if the camera is intermittently losing communication with the lens. When no lens is attached and the camera is powered, on, the display normally reads, f/0. I would recommend removing the lens and examining the contact points on it and the camera body for an debris, moisture or other matter that could potentially interrupt the connection. While the lens is off the body, you could use a lens tissue to gently clean the connections.

Agree that this is a good suggestion to check.  But, FWIW, when my D7200 is powered on with no lens in place, the aperture value reads f/2.8, not f/0.  I have never seen f/0 on my cameras.  But, I don't have a D600 series camera.
