A lot of other reviews focus on how the a7C compares to other full frame cameras but if you’re using another sensor altogether, Sony’s developed a very nice step up. The term full frame comes from film cameras and refers to the sensor in the camera. Smaller sensors mean smaller cameras and lenses that also weigh less. Well, the a7C is small, light, and less expensive than previous entries into full frame. It won’t replace your larger Sony camera but if you’re moving into the full frame world, the a7C is a great first step.
