help Sony Alpha A7S III FAQ
Can the Sony a7S III record 4K at 120 fps internally?
Yes. It records 4K at up to 120 frames per second with 10-bit 4:2:2 color, making slow-motion video one of its defining capabilities.
Why does the a7S III have only about 12 megapixels?
Sony prioritized large photosites, fast sensor readout, and low-light video over high-resolution still photography. The 12.1-megapixel full-frame sensor is excellent for 4K production but leaves less room for heavy still-image cropping than an Alpha 7R model.
What lenses fit the Sony a7S III?
It uses Sony's E-mount and works with full-frame FE lenses from Sony, Sigma, Tamron, and other manufacturers. APS-C E-mount lenses can attach too, but they force a cropped image area.
How is the a7S III different from the Sony FX3?
Both use closely related full-frame sensors and offer 4K 120p recording, but the FX3 has a cinema-oriented body with mounting points and active cooling. The a7S III retains a high-resolution electronic viewfinder and a more traditional mirrorless-camera design.
