It's like the power of the A7 series in a smaller package, perfect for travel, street and family photography.

Sony A7C (original)

This was the first model in the series and it revolutionised the perception of the size of a full cell camera. It packed much of the technology of the Sony A7 III (24 megapixel sensor, good autofocus) into a much smaller, ”rangefinder” style body with the viewfinder in the top left corner of the body. The side-facing screen made it instantly popular with vloggers and travel photographers.

Best for: travel, vlogging, street photography and general everyday photography when you want full-frame quality in the smallest, most discreet package possible.

Video capabilities are also improved. Externally, it is very similar in size to its predecessor. A great choice for those who loved the size of the A7C but want more resolution, more modern autofocus and better video features. An excellent compromise between size, weight and performance.

Sony A7CR: Compact resolution monitor

This is a special model in the A7C series, where the ”R” again refers to the resolution. In effect, Sony has taken the staggering 61 megapixel sensor of the A7R V and packed it into a small A7C series body! So you get the incredible detail of the A7R series in the compact size of the A7C series. The trade-off in this combination might be a slightly more modest viewfinder or continuous shooting speed compared to its big brother, the A7R V.
