The Real-World Difference

For still photography, the Sony A7 III is still extremely capable. It delivers excellent full-frame image quality, strong autofocus, and great battery life at a much lower used price.

The Sony A7 IV is the better hybrid camera. The jump to 33MP, improved autofocus, 10-bit video, 4K60, and a fully articulating screen make it much more flexible for modern creators.

Used Buying Advice

A clean Sony A7 III with a low shutter count can be one of the best full-frame values on the used market. Before buying either camera, verify shutter count, inspect the sensor, test autofocus, and check the card slots, USB port, HDMI port, and rear screen.
