Slow, expensive, mediocre lenses holding micro 4/3rds back

How would they work on 4/3 though?

As far as I know, there are no micro 4/3rd to 4/3rd mounts. You can get
electronic adapters (or manual) to go the other way, but the electrical
performance of 4/3rds lenses on micro 4/3rds mounts is iffy. Focusing can
be slow, not all of them work, etc.

My question is would a full frame or DX cheap 300mm zoom be sharp on 4/3 format? I suspect not. You could easily make the adapter
with cardboard tubes.

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...

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 --
