Mine is a C330 S - the one that came after the C330 F. Like most things, as the newer models came out, more plastic was used the quality suffered. I may have a lead on a knob off of a C330 donor camera. I'll be in touch if things don't work out.

I have no idea if how one replaces the knob. Is it a simple job?

Thanks for your thoughtful reply!

But if you are living in the US, check www.keh.com first.

My impression is that these plastic knobs are a design failure . they seem to shear off and break quite easily.
