Hi Nicole
both Faye and I use G2's and must say that while the Leica carries the badge the Contax, at least to us, outperforms it. One comment re the focus with the 90mm fully open, which I use often, is correct but is a very minor observation. If you have ever tried to load film into a Leica then you will appreciate the G2! We use them in the studio but recently have been undertaking a project on Glasgow which has been street photography and I must say they have performed superbly even when we have been shooting from the hip! I will post a couple of images but I would say that, and I am sure you alreay know this, you can purchase a complete G2 kit for the price of a M6 body!
Kind regards
