Enjoyed the Nikon 1 system while I had it, unfortunately it lacks in one area that I like to shoot and that's low light. The 1" sensor just isn't great pass 800 ISO. Image clarity greatly diminishes. I still think the M43 sensor is the perfect compromise in terms of size and performance. The 4/3 ratio sensor means glass can be made almost as small as Nikon 1 lenses, while still being competitive enough against APS-C.
