Peter,
What are you mounting your B300 to? Which model camera?
I do not experience any vignetting if the C730 is at the telephoto end of
its range. Naturally there is vignetting at the wide angle end of the zoom
range.
You mention a bayonet, are you using this on an OM? If so, what focal length
are you putting it on?
I have no problem with the mounting method. Mine has been on and off many
times without incident.
Mark

convertor, but I still need to study my slides. Vignetting is definitely
quite noticable, which is a shame. Second, I don't particularly like the
fact that I need to screw it into the filter thread every time I want a bit
longer lens. The filter thread is clearly not made for this purpose,
whereas the bayonet is.

But it doesn't feel very safe to have a lot of glass hanging off a
polarizing filter.
