Thanks guys, the GAS passed. A spotmatic was my first real slr and would still be using it if it hadn't been stolen some 15 years ago from a work truck. Part of my frustration on that was I could have gotten a spotty and a 50mm for about what i spent on the 2 rangefinders I bought dumb decision on my part. The 150mm for the 645 well several years ago when I last had a 645 I found myself wanting a 150 to supplement my 75 about 20 to 25 percent of my shots. I'd rather crop with a longer lens when needed. well they come when the money is here and the price is right.
