Photography priorities
Both use APS-C sensors around 26 megapixels. Compare subject detection, controls, in-body stabilization and the lenses you intend to use.
Video priorities
The Sony a6700 offers 4K high-frame-rate options with cropping at 120p. The Fujifilm X-S20 offers a 6.2K recording mode. Higher resolution is not automatically better for every project.
System considerations
Sony E and Fujifilm X are different lens mounts. Price a complete kit and check third-party lens availability before choosing.
Verdict by workflow
For autofocus-led solo production, put the a6700 on your shortlist. For creators prioritizing Fujifilm color options and 6.2K capture, investigate the X-S20. Neither is universally superior.
