$800 for a 70-300mm Oly or a 100-300mm Panasonic. Neither is a star
optically, both are slow. Meanwhile, standard DSLR lenses are faster,
better optically and about 1/2 the price. Nikon's 70-300mm and
Olympus's DSLR 70-300mm. Micro 4/3rds and slow does not mix well.
You can't just jack the ISO up to 800 on a whim, you'll end up with
terrible noise, compared to modern APS DSLRs. So slow lenses are a
killer.

I may soon have at least part of the answer. A friend is borrowing a
couple of my sharper (on film) Nikkor AIS lenses (the 35-135mm
f3.5-4.5 and the 135mm f2) to try on his new "fawn-see" Panasonic
4/3rds pro video camera...

Then don't buy them. Simple.

I don't know. For fun, I once mounted a 17-55mm f2.8 Nikon on a
4/3rds camera, I never really analyzed the results it produced.

Don't be a flip, it reminds me of some of the mindless fanboys on
Dpreview. What if you NEED lenses of that focal length? Your other
choice is dump the camera, buy a new system.

Your other choice is to STFU, but you aren't ever going to take that
option, are you?

From what my friend reports, the zoom above is sharper than the Panasonic
4/3rd lenses he has, with the 135mm f2 being much sharper... He reports
a new market for Nikkor AIS lenses (with diaphragm ring detents removed)
for use on the new 4/3rd video cameras. Good, since I have many to sell --
