Well it's a very interesting topic actually . Most of us grew up in the 3:2 world but since shooting MF 4:3 i have grown to love this format framing and I simple do NOT crop almost never with this system. 4:3 matches my vision best and when i have to shoot 3:2 with my Sony I can feel the struggle to shoot 3:2 again. When I did the S2 review and Phase kit your working with both at the same time and it is very strange to do that but I did prefer the 4:3rds every time. The S2 would be a adjustment just like when i shoot the Sony it is a mental adjustment. I don't really like it but I have been shooting so long that you mentally find ways around it. I wish my Sony was 4:3 rds to be honest.
With this system I will crop and I hate to crop ever.
