I don't think so, but I'm not 100 ertain. The P an P2 lenses are physically
identical, with the exception that the P2 lens has the optics further back
in the barrel. The diameter of the barrel on the P/P2 lenses is 42mm, but
my 60's era Pradovit uses a lens which has a 45mm barrel. I guess if your
projector uses a 42mm barrel, then a P2 should work.

I've definitely noticed less "pop" with the P2002 than other projectors.
It's amazing how much air flow this projector produces. Of course it
was designed for professional continuous projection so I guess that's to
be expected.

It seems like a flat field lens to me. It also makes sense that it is since
this is Leica's top of the line lens which is designed for glass mounted
slides. There's not much curvature in a glass slide :-)
