The two lenses I mentioned are for a larger 'sensor'. They are the old full frame zuiko from film days <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/smile.gif' class='bbc_emoticon' alt='

No. The Zuiko is for smaller sensors.
30mm f3.5 on 1.5x crop APS-C.
Equivalent lens on 4/3rds 2x crop:
Focal length 22mm (!!), not 50mm.
f-value : f2.6.
f2.8 is pretty close to f2, don''t you think? So, if the 50mm f2 is not too slow for you on 4/3rds, the 30mm f3.5 will not be too slow either on NEX.
