... substantial advantage ?

[dee]

My 50 f2 Summtar , non collapsed adds a considerable weight to the G1 , but it actually makes it easier to hold for me , maybe 'cos I am used to a Contax / Kiev and my M8 .
I thought I wanted smaller / lighter and I am prefering smaller / weightier !
LOL

Heavier lenses actually balance very nicely on the larges G/GH bodies. I also prefer the heavier lenses.
