I lusted horribly for a black G2 kit when they were new in the late 90s, to the point that I kept an advertising slick for it taped to the inside of my credenza door at work to inspire my savings. At the time I had no RF gear at all, and it seemed the ultimate small camera for me to supplement my Nikons.
I never purchased any G system gear at all. In the early 00s I picked up a Bessa T and the Leica CL lens pair, and I was off down the M rabbit hole. I’m now heavily invested in Leica M for the second time in my life.
But... that old Contax pull is still there.
My biggest concern with buying a G in 2017 is longetivity. G1s are fairly inexpensive, but G2s are pricey. With my luck I’d pick one up and it would croak in a year or two with no repair parts available. Already I understand many cameras are showing LCD problems.
In some ways I wish I had gone G back before I started again with M. Yes, M was a comfortable old friend - but as my eyes age the G’s autofocus would be appreciated!
