Sony a7C vs Sony a7S Comparison

The Sony A7c and A7S are two Mirrorless cameras that we will compare in this article. The Sony Alpha A7c is a camera in the Advanced Mirrorless class, whereas the Sony Alpha A7S is in the Pro Mirrorless class.

The Sony A7c will be released in September 2020, while the Sony A7S will be released in April of the same year. The A7S is six years older than the A7c, as seen in the graph. Let’s see if the age difference between the two cameras significantly impacts their performance.

The Sony a7C and Sony a7S are both Sony cameras, but they are designed for different purposes. Here’s a detailed comparison:

Image sensor: The a7C has a full-frame image sensor (24.2 megapixels), while the a7S has a full-frame image sensor (12.2 megapixels). The a7S has a lower resolution than the a7C, but it has a larger pixel size, allowing it to perform better in low-light conditions.

Autofocus: Both cameras have sound autofocus systems, but the a7C has a more advanced autofocus system that includes real-time Eye AF and Real-time Tracking, which are optimized for still photography.

Video recording: The a7S is a better option for videography, as it can record 4K video at a high bit rate and has a full-pixel readout that reduces moire and aliasing. Additionally, it can record in S-Log2 and S-Log3, which provides a more excellent dynamic range for post-production color grading.

Ergonomics: Both cameras have compact designs that balance portability and handling well.

Price: The a7S is generally more expensive than the a7C.

Battery life: The a7C has a longer battery life compared to the a7S, which makes it more suitable for extended shooting sessions.

Deciding between the new Sony A7C and the A7 III comes down to more than just picture quality and performance; it also comes down to other critical features, such as weight and handling.

However, while the Alpha 7C is unquestionably smaller and lighter than the A7III – it’s only slightly larger than the APS-C sensor A6600 – it does so at the expense of a significantly less intuitive user interface.

In conclusion, the Sony a7C and Sony a7S are good cameras, but their choice of them depends on your specific needs. If you’re looking for a versatile full-frame camera that can handle a wide range of photography and videography applications, the a7C might be the better option. On the other hand, if you’re looking for a specialized camera optimized for low-light photography and videography, the a7S might be the better choice.
