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

Neither is a star optically, both are slow. Meanwhile, standard DSLR lenses are faster, better optically 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... --DR 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 -- http://www.donferrario.com/ruether/fs.htm ;-) --DR |
