FAQ

Which camera is better for photography overall, Sony A7C II or Sony A6700?
The Sony A7C II is generally better for photography that prioritizes image quality, dynamic range, and low-light performance because of its full-frame sensor. The Sony A6700 remains highly capable, especially for action and telephoto work, but it does not match the full-frame advantages of the A7C II.

Which camera performs better in low light?
The Sony A7C II performs better in low light due to its larger full-frame sensor and larger pixel pitch. This results in cleaner high-ISO images and better shadow recovery compared to the APS-C sensor in the Sony A6700.

Is the Sony A6700 better for video than the Sony A7C II?
The Sony A6700 has advantages for high-frame-rate video because it supports 4K at up to 120p. The Sony A7C II focuses more on full-frame image quality and oversampled 4K, making each better suited to different video priorities.
