Thanks to everyone for their thoughtful advice. I was able to get a pretty good understanding of the G1's strengths and weaknesses from your posts. I went ahead and bought the used G1 with the 45/2 Planar since it seemed like a good price. I downloaded a scanned copy of the manual and have been reading it while I wait for the unit to arrive, and looking at some pictures posted on the web shot with this combination, which I must say really impress me. I think the chief value of having this camera is that I plan to always have it with me so maybe I will shoot more pictures with it.
As for the 139Q with the pancake Tessar, I like mine, even though as Joseph says, it can be a little tricky to focus with that small ring. But, it is a great little lens and is razor sharp and produces great colors. The 139 is at its best when carried just as it is with this lens on it, when you add the winder, it gets heavier than it needs to be and it spoils the package. I guess I will see which set-up I like best.
Thanks again to all for your responses.
