So I am relative new to the 4/3 market. Just got a Lumix G3 with two of the X series lenses. Sold some Nikon stuff I wasn't using. Looking to expand my lens and wanted opinions on a couple options. Do I get the Leica 25mm or the 20/1.7? The Oly 45/1.8 or the Leica DG 45/2.8? I am leaning towards the lesser cost lenses, but did like the OIS and macro capabilities of the Panasonic Leica 45. Is the 7-14 worth the cost?
