Faunagraphy and all,Czech photographer Petr Bambousek used to shoot the Olympus 300mm but switched to the Panasonic 200mm because he liked the focal length more. His review is worth a read.

I do not own the 200mm - I would if 300mm wasn't my most-used focal length (I agree with Fsi that it has better rendering for out of focus areas). I have been shooting 300mm on Micro Four Thirds since I got into photography, starting with a Canon FD 300mm f4 S.S.C.200mm is too short for me.
However, I do own the Panasonic 50-200 which comes close to the 200mm in terms of performance. In terms of AF speed, it's just as fast as the 300mm Pro. I find the 300mm slightly faster, but it's so close that it might be my bias. For a long time, I thought that the AF was slower on the Panasonic. It turns out that having the OIS on was slowing the AF ... ever since I turned it off, it's about as fast as the 300mm Pro.
However, as I've said, the 300mm Pro's OIS syncs with the camera's IBIS to make the excellent Olympus stabilization downright unreal. On paper, it provides a 1 stop advantage over IBIS alone, but I know for a fact that I get much better stabilization than I used to with my Canon 300mm f2.8L. What I mean is, on paper the 300mm f4 OIS + Olympus IBIS should be equal to the 300mm f2.8 used with the body's IBIS alone (since f2.8 has an inherent 1 stop advantage), but I find the f4 lens rock steady in low light, leading to sharper photos. Of course if you're shooting fast action in low light, the f2.8 lens will be better.
The 300mm Pro has some nice touches that would make me prefer it over the 200mm, even if FL weren't a factor. Olympus tests each focus motor individually, and only the best ones go into the 300mm Pro and 150-400 Pro. The 300mm Pro has 2 AF motors which make AF fast. I do not know about the Panasonic. It has an ARCA Swiss tripod foot. And an integrated lens hood. Also has a programmable button which I do not use. The Panasonic's button won't work with the OM-1.
Also, keep in mind that a 1.4x TC (included for free with the Panasonic 200mm) will bring it to 280mm f4. The 300mm Pro has an inherent reach advantage that means that it can go all the way to 1200mm equivalent whereas the Panasonic maxes out at 800mm. Even with the 1.4x TC, the 200mm is plenty sharp, but a bare 300mm will always be sharper.
Thanks for the information you have been providing and for the links to Petr Bambousek's site. He has a lot of good info on lenses, the OM-1, and on his own photography. Again, this discussion has been helpful to me as I consider getting into M43 with the OM-1.
