When I showed it to my son Tim, who now owns a G1,he went : wow ! which I fully support, model; angle, BW conversion, are simply among the best. Now, you write that there's on board conversion and my question is; does it keep converting even if the lens is an M or an R or any other than micro 4/3 lens ? which would be a major impediment in my view. Hope not. Renewed congrats and thanks in anticipation for your input Amiti?s de Metz Philippe Le 2 d?c. 09 ? 08:20, H&ECummer a ?crit : > >> Date: Wed, 2 Dec 2009 06:44:52 +1000 >> From: Geoff Hopkinson <hopsternew at gmail.com> >> Subject: Re: [Leica] The Pana 20mm f1.7 on the GF 1 >> To: Leica Users Group <lug at leica-users.org> >> >> Howard its an very effective environmental portrait.
