This is the second time I’ve put up a chart of various sensor sizes. I stole this one from a new site by Thom Hogan. It’s called byThom sans Mirror.
Covering the new breed of interchangeable lens cameras: m4/3, NEX, NX, and Nikon 1
Many camera owners weather they’re Point-and-Shooters or Digital SLR owners have been considering one of the cameras in this category but for very different reasons.
So head over to the site and take a look. You just may find a camera that fits your needs. If you already know what you want head over anyway just to get a very knowledgeable person’s opinion.
