    Objects inside Nikon foucsing screen

    I have an F with some dark bits that appear to be inside the focusing screen. Age-related I'm sure. Are there any surprises when taking a screen apart, such as alignment or shims or foam? Or is it a simple process to clean these up?

    thanks,

    s-a

    Just undo the screws, it comes apart easily, just don't touch the plastic fresnel, it marks real easy.

    Are you sure that it is in the focus screen and not on the mirror?

    Usually stuff on the mirror isn't visible on the screen, except perhaps as a general dimness. Sharp specs are generally on the screen, or in between the screen components, as is the likely case here.

    As Bob says, the Nikon screen comes apart easily, for this semi-routine task.

    Maybe also check the state of your mirror/prism foam: that could be where the dark spots originated before getting inside your screen...

    Thanks for the replies. I was hoping it would be an easy task; lately it has become very difficult to ignore them when framing. (Probably just GAS, looking for an excuse to buy something.)

    Tooling is another huge category for GAS, there are screwdrivers, sharpening stones and jigs for them, precision grinders for making pin spanner wrenches, lathes, milling machines and tooling for them, a whole new universe.
