[QUOTE="hark, post: 783254, member: 13196"] It sounds like there is a communication issue between the camera and lens. As Sparky mentioned, when using a lens with an aperture ring, that ring needs to be set to the smallest aperture (usually f/22 or higher depending on the lens). You control/change the aperture only through the camera. There might even be a lock switch on the lens to lock the aperture at that setting so you don't accidentally bump it. If you aren't using lenses with aperture rings, then consider cleaning the contacts inside the body cavity. I had that issue with my 300mm f/4 PF. In addition to cleaning the contacts on the lens, I also VERY CAREFULLY cleaned the contacts inside the body with this technical use alcohol. It is NOT designed for sanitizing - just cleaning so it works better than traditional rubbing alcohol. I was able to remove more black stuff from my contacts with the technical use alcohol that didn't come off with rubbing alcohol. Be sure to use a lint free cloth. I used one that I purchased as a packaged set via Amazon for cleaning eyeglasses.
