Sony α6600 vs Sony α7C

The Sony α7C performs similarly to the Sony α6600, although it has a slight edge thanks to its backside-illuminated full-frame sensor, as opposed to the α6600's APS-C sensor. As a result, out-of-camera image quality and high-ISO performance are a bit better on the α7C. The cameras are similar in size, although the α6600 has a couple of extra custom buttons and a larger, more comfortable EVF. Both cameras are weather-sealed, feature in-body image stabilization, and use Sony's highly effective autofocus system; however, the α7C uses a newer version with more settings to fine-tune AF performance.
