The Sony a7R IV uses Sony’s Multi Interface Shoe. For on-camera TTL and HSS, choose the Sony-specific version of a flash, not a Canon, Nikon or generic version with a similar name. Sony lists the HVL-F60RM2 as compatible with the a7R IV; Godox lists Sony-mount V1Pro, V1, V860III, V350, TT685II and TT350 families for its Sony system. For off-camera work, keep transmitter and flash in the same wireless ecosystem and update camera and flash firmware before important work.

Buying tips
- The Sony suffix matters: Godox S is Sony, while C and N are different camera systems.
- TTL/HSS capability depends on camera, flash, trigger and firmware combination.
- Use radio triggering rather than assuming an optical wireless mode will meet your placement needs.
