My d700 has become possesed. When I use an AF lens no problems at all, but when I use my MF legacy lenses all of a sudden, the camera has decided that all of them are a f/8 lens at max aperature. I went into menu and made sure that all of the settings were correct for non-cpu lenses. But when I place say my 55 micro on it, and use either manual or aperature mode it defaults and acts as if f/8 is the max aperature. Even if I have the aperature ring at f/4 it exposes as is if it were at f/8. Way over exposed, I can fool it by dialing in minus 2 on compensation, but that is a pain in the... It worked fine until the other day, does anyone have an idea? Joe
