I recently purchased a couple of used Lumix bodys (GF1 & G2) which came boxed and complete with 2 lenses, the 20mm and 14-45. I already had the Lumix LVF1 finder from my LX5 compact. The Panasonic G series is completely new to me as my other cameras are the Canon DSLRs 5D & 7D . However after much soul searching I have decided to heavily cut back the canon gear, hence the arrival of the Panasonics. It's early days for me, as the GF1 and 14-45 were the first to arrive I thought it was great (still do) but the LVF1 is a sure hazard when mounted, twice I managed to nudge it whilst fitted. So, realising I was missing a prime I spotted a deal with a mintish G2 and 20mm. I am now smitten. I love the lightness, small size and the great lens. I'm especially keen on using manual focus. I had read of how the image is magnified either in the viewfinder or LCD to aid precise focusing. Having now used it, I think it'll be staying around for a while....It's brilliant. Both G's were purchased to encourage me to take more pictures as the heavy DSLR kit is always off putting and the little sony HX30 is great for family days out but fiddly when I want to take over. I'm playing and using the G2 at every opportunity and learning more each time. Whilst I'm perfectly happy to continue with what I have, I'd like to read up on what other models in the M34 G series can offer. Specifically the AF speed and IS0 ability. Does anyone have a link that details all the models past and present that Panasonic have made. I have absolutely no idea what the differences are between the G, GF, GH and GX. Anybody?
