Here is a complete comparison of the Sony A7c and the Sony A6400, both Advanced Mirrorless digital cameras produced by Sony and reviewed here. Even if the resolution of the A7c (24MP) and the A6400 (24MP) is almost the same, the sensor sizes of the A7c (Full-frame) and A6400 (APS-C) are significantly different.

The a7C was introduced 21 months after the A6400, placing the two cameras a generation apart in terms of technological advancement. Each of the cameras has a body that is similar to the other (Rangefinder-style mirrorless).

The Sony a7C and Sony a6400 mirrorless cameras from Sony, but they have different target audiences and features. Here is a comparison of the two in detail:

Form factor: The a7C has a full-frame sensor and a compact body, making it an excellent choice for travel and street photography. The a6400, on the other hand, has an APS-C sensor and a larger body, making it more suitable for sports and wildlife photography.

Image quality: The a7C’s full-frame sensor delivers superior image quality with better dynamic range, low light performance, and a shallower depth of field. The a6400’s APS-C sensor can still deliver excellent images, but it can’t match the full-frame quality.

Autofocus: The a6400 has Sony’s advanced real-time autofocus system with 425 phase-detection AF points, making it faster and more accurate than the a7C’s autofocus system.

Video: The a7C has 4K video recording capabilities with full-pixel readout and no pixel binning, while the a6400 is limited to recording in 4K UHD (3840 x 2160) resolution.

Price: The a7C is generally more expensive than the a6400, reflecting its full-frame sensor and compact form factor.
