The NEX-F3 is one of three Sony mirrorless camera models released in 2012, and it’s the company’s eighth since the launch of the NEX line in 2010. The NEX-F3 borrows heavily from higher-end models, but also taps much of the technology found in its predecessor. So is there any big evolution in sensor quality for the NEX-F3? Or were most of the changes to the camera cosmetic? DxOMark has some answers.
