I just got my adapter. In my photographic life, I grew up wit the 1.5 crop factor Nikons .... My "normal" has always been near the 35mm FOV of a 60mm lens. While I'm not really good optics guy, the key lens characteristics in the range of FOV seem about the same for lenses. Perhaps, this has fixed my eye to shoot longer rather than wide. I would prefer a 1.3-1.6 crop sensor, but I'm no where willing to pay 5K for full frame, 2.5K starts to be interesting ....
Then the reality sets in, I have an M6, its fun, but work ... If I had shot with it the preceding three years, perhaps I would be better with my tools. I pick up the Panasonic G1, and I can get my vision of what the photo should be out of the beast. Much the same with the Fuji 645.
So, I have a CV 15, CV25, CV40 and Leica 50mm Summicron collapsible all waiting to be played with as my CQ adapter just arrived. Will it be the same experience and the M6, obviously not, I do hope that this tool will let me get my ideas out of sensor land and into web and print space. For me, that is the idea be the "sensor" 35mm, 120/220, APS-C or micro 4/3!
