The Sony a7C is the company's latest and smallest full-frame interchangeable lens camera. It fits a 24MP full-frame sensor and image stabilization into a body more closely resembling the APS-C sensor a6600.
Basically an APS-C with better dynamic range and low light capability. 2 very strong points but not enough to convince me to move away from my a6400 and a5100. I'm sure APS-C lenses wont play well with the a7C and FF E-mount lenses aren't cheap or light weight.
Interested to see how the quality of the kit lens stacks up though. The standard APS-C kit lens is poor, I'm guessing this one will be good but not great.
