Do multi coated filters compensate for single coated lenses?

[Early Riser]

A multi-coated filter will lose less light at the filter, but that's all. In other words, using an uncoated or single-coated lens with a multi-coated filter will mean performance just a little closer to that of the lens with no filter. compared with the same lens and a single-coated filter. There's no way a filter can improve lens performance, only impair it less!

David, I agree with you that the addition of a filter degrades an optical system, however as I commonly use B&W contrast filters on my lenses anyway I am already dealing with that loss.
