Based on your description, you probably want the Sony Alpha system. Or do you want a compact mirrorless camera like the Nikon 1 cameras? That would be the Sony e-mount or NEX cameras. I'm not sure which way you're leaning here.

I have a Nikon 1 J3 mirrorless and three lenses for it; its a nice little camera and takes very sharp photos but it'll always play backup to my DSLRs with their proper viewfinders and much longer list of features.
