Compare the Godox TT685 II and V100 for Sony cameras: power, light quality, and trigger compatibility, plus clear rules for picking the right speedlight.
Quick answer
Choose the Godox TT685 II if you want a dependable, lower-cost Sony speedlight for events and off-camera work with the Godox X system. Choose the Godox V100 if you need more power, smoother round-head light, and faster full-power bursts for portraits or demanding on-location shoots.
Power and light shape change how you shoot
The V100's 100Ws output and round head give you more light and a softer, more natural fall-off than a rectangular fresnel head. That matters when you bounce into high ceilings, use modifiers, or shoot portraits where the edge of the light beam is visible.
The TT685 II is the smaller, lighter option. It trades some output and the round-head look for easier handling on-camera and a lower price, which is often the deciding factor for event photographers who work with direct or bounced flash.
Off-camera use and trigger compatibility
Both flashes are built for the Godox X system, so off-camera flash for Sony is straightforward: add an X-series trigger for your camera and you can control power and groups remotely. The TT685 II includes a built-in 2.4GHz Godox X receiver, and the V100 supports TTL and High-Speed Sync, so either can slot into a multi-light setup.
The practical difference is workflow. The V100's magnetic modifier mount makes it faster to add grids, gels, or diffusers on location, while the TT685 II's simpler head suits photographers who mostly bounce or use a single softbox.
Where the spec sheet stops
The supplied catalog information does not list recycle time, guide number, or battery type for either flash. If those details decide your purchase, check the full specifications before ordering rather than assuming they match. What the catalog does confirm is the V100's 100Ws output and its up-to-100 consecutive full-power flashes, which points to heavier-duty use.
Decision rules for Sony shooters
- Budget-first or high-volume events: Pick the TT685 II when you need a reliable on-camera flash for weddings, parties, or press work and want to keep budget for lenses or a trigger.
- Portraits and modifier-heavy location work: Pick the V100 when you regularly use softboxes, grids, or gels and want the round head's smoother fall-off and the magnetic mount's faster setup.
- Multi-light setups: Either flash works with a Godox X-series trigger for Sony, so choose based on the power and light quality you need per head, not on trigger compatibility. Confirm you have the correct Sony-fit trigger before building a multi-flash kit.
