The Sony a7S II and the Sony a7C make for an interesting comparison! On one hand, these two cameras are clearly targeted at different audiences. The a7S II is a 12-megapixel, low-light camera with some of the best video specs available on the market… that is, they were some of the best video specs back in 2015 when it was released. Meanwhile, the Sony a7C is aimed at more of a consumer audience, but it’s a whopping five years newer (which is ages in the world of electronics). As a result, the a7C actually beats or matches the Sony a7S II in many ways overall, even for video. Here’s what you need to know.

As you can see, the Sony a7C actually beats the a7S II in almost every spec, and the few exceptions (like the higher-resolution rear LCD) are not going to be must-haves for a typical photographer. The Sony a7C has a higher-resolution sensor, more frames per second, a bigger buffer, a much longer battery life, and more.
That said, don’t laugh off the Sony a7S II. It wasn’t designed to be a high-speed, high-resolution beast. Instead, it was made to have amazing low-light performance and impressive video features, and it definitely delivers. Even today, you’ll have a hard time finding any cameras with better performance at ultra-high ISOs, both for stills and for video. And because it’s getting pretty old, you can find used copies of the a7S II selling for amazing prices today, easily under $1000. Not bad for what was once a $3000 camera!
Summary and Recommendations
Broadly speaking, between these two cameras, it’s easy to recommend the Sony a7C. The a7C might be aimed at a more consumer audience, but because it’s five years newer than the a7S II, it has a ton of new and useful features. Landscape photographers, sports photographers, and everyone in between will find something to like about the a7C over the a7S II. The only exceptions would be videography (where the two cameras are quite similar) and ultra-low-light photography, where the a7S II is ahead.
What does the Sony a7S II offer over the Sony a7C?
- Better performance in extremely low light conditions where your ISO is 25,600+
- Lower prices on the used market today
What does the Sony a7C offer over the Sony a7S II?
- Twice as many pixels (12.2MP vs 24.2MP)
- Faster frame rate (10 FPS vs 5 FPS) and bigger buffer – better for action photography
- Substantially battery life with both the viewfinder and rear LCD
- Lighter weight (118 g / 0.26 pounds lighter)
