Which one is worth buying, Sony a7m3 or a7m4?

The a7m4 is equipped with a higher-pixel sensor and can take higher-resolution photos, making it more worth buying.

A7m4 has better noise control than a7m3 at high ISO. Even so, both cameras have the same maximum ISO when shooting stills. Interestingly, the a7m4 limits the maximum ISO value for video shooting, while the a7m3 has the same maximum ISO value for both photo and video shooting.

The continuous shooting speed of the two machines is the same, 10 frames/second. But there is a big difference in buffer capacity. The a7m3 can buffer 79 RAW+JPEG images, which is acceptable for similar models. However, the a7m4's 828 RAW + JPEG cache capacity, combined with the BIONZXR processor and CFexpressA card, can achieve almost uninterrupted continuous shooting.

In terms of anti-shake, the a7m4 has been slightly improved, and a new "active anti-shake" mode has been added.

Sony has added a series of new creative styles to the a7m4 for users to choose from, but these do not seem to be of much use to photographers who shoot photos in RAW format, and may be of greater use to video shooters. usefulness.
