Well, that would suggest that those of us who are happily (and successfully) using a variety of legacy MF lenses on Panasonic and Olympus m4/3rds cameras have somehow made a bunch of poor choices.
However, if you're looking for "the best mf 35mm lens to put on a GF1", there are lots to consider, including:
* Contax G 35/2
* Canon FD 35/2
* Canon FD 35/2.8
* Konica Hexanon 35/2
* Konica Hexanon 35/2.8
* Minolta Rokkor 35/1.8
* Minolta Rokkor 35/2.8
* Nikkor AI-S 35/1.4
* Nikkor AI-S 35/2
* Nikkor AI-S 35/2.8
* Olympus OM Zuiko 35/2
* Olympus OM Zuiko 35/2.8
* Pentax Takumar 35/2
* Pentax Takumar 35/3.5
* Voigtlander Nokton 35/1.2
* Voigtlander Nokton 35/1.4
Some of these you'll be able to pick up at reasonable, if not cheap, prices. Others will be considerably more expensive (I haven't listed Contax C/Y or Leica M and R lenses).
If you search for some or all of the lenses I've listed -- on this forum, on the
Alternative Gear and Lenses forum at FredMiranda.com, on
ManualFocus.org, and on Flickr -- you'll find lots of pictures made with particular 35mm focal length lenses. Once you find one that seems to offer the look you're after, you can look for a copy on eBay or on the Buy and Sell sections in this and other forums.
Hopefully, other GetDPI members will comment on the lenses I've listed and offer alternative suggestions. But, if you appreciate lenses that draw in all kinds of fascinating and beautiful ways, pretty much the worst thing you could do is restrict yourself to dedicated m4/3 lenses.
