Favorite legacy lens to use on Micro 43?

A beautifully built, fast, tele-prime giving me the equivalent of 270mm with my Panasonic Lumix G1.  Needless to say, it doesn't work perfectly in all light conditions (better in the warm, evening light of winter).

The manual focussing of the G1 is a "must" and so is a tripod.

But, if one works at it, one gets some good results.
