The Sony a7R IV uses Sony Multi Interface Shoe flashes and Sony-specific third-party models. Do not treat a physically mountable generic flash as equivalent: TTL, high-speed sync and radio functions depend on the Sony version, normally marked S. Power matters for bounce portraits, while a compact flash makes more sense for travel. Check the exact a7R IV firmware and the flash maker compatibility list before a paid event, particularly if you plan to use HSS, off-camera radio control or a transmitter. For a large modifier or bounced ceiling light, compare head tilt, usable output and recycle time; a small travel flash can be easier to carry but slower to light a room.

The picks, in detail
Sony HVL-F60RM2
Sony HVL-F60RM2 is Sony’s high-output radio flash for photographers who want a native Multi Interface Shoe unit for bounce and event work. Its GN 60 rating at ISO 100 and 200 mm and Quick Shift Bounce head make it the strongest Sony-brand option here. The metal shoe foot and sealing matter when the camera and flash will see sustained location use.
- GN 60 at ISO 100 and 200 mm
- Quick Shift Bounce head tilts from -8 to 150 degrees
- Sony radio wireless control through the Multi Interface Shoe
- Native Sony radio system avoids a separate transmitter for compatible off-camera sets
- High guide number gives more latitude when bouncing at longer focal lengths
- It is the largest and most expensive Sony option in this group
- The premium is hard to justify for simple on-camera fill
Sony HVL-F46RM
Sony’s HVL-F46RM provides a smaller native-radio alternative to the F60RM2. Sony rates it GN 46 at ISO 100 and 105 mm, with a head that bounces up to 120 degrees. Sony Japan lists the model as discontinued, so buy only an exact remaining-stock listing rather than assuming it is a current catalog flash.
- GN 46 at ISO 100 and 105 mm
- Radio wireless Sony Multi Interface Shoe flash
- Bounce range reaches 120 degrees upward
- More compact native Sony option than the GN 60 F60RM2
- Radio capability suits a Sony-only multi-flash kit
- Sony lists it discontinued in Japan
- Remaining stock can command an uneven legacy price
Sony HVL-F28RM
The HVL-F28RM is Sony’s compact AA-powered flash, useful when the a7R IV kit needs to stay light. It has P-TTL/ADI metering, radio wireless operation and a built-in 24 mm wide panel. Its 219 g body and GN 28 are a better match for travel fill and small bounce setups than high-ceiling reception rooms.
- GN 28 at ISO 100 with 50 mm coverage
- Two AA batteries provide power
- Built-in wide panel covers 24 mm
- 219 g body keeps a travel kit compact
- Sony specifies 40 flashes at 10 fps at 1/32 power
- GN 28 limits bounce range compared with larger flashes
- AA cells must be carried and replaced separately
Godox V100S
Godox’s V100S is the Sony-TTL version of its 100 Ws round-head flash. It combines HSS to 1/8000 s, a 2.3-inch touchscreen and Godox X radio sender/receiver operation, so it suits a photographer already using Godox strobes. The built-in 7.2 V, 2980 mAh battery is rated for about 400 full-power flashes.
- Sony TTL version is V100S
- 100 Ws maximum flash output
- 2.3-inch full-color touchscreen
- Godox X radio lets it control compatible flashes and studio strobes
- 100 Ws output is useful for bounce or larger modifiers
- 616 g with battery adds noticeable weight to an a7R IV
- Its rechargeable pack is proprietary rather than an AA fallback
Godox V1Pro S
The V1Pro S is a Sony-TTL round-head flash with 76 Ws output and an integrated 2 W modeling lamp. Its 7.2 V, 2980 mAh battery is rated for roughly 500 full-power flashes, and Godox specifies a 1.3-second recycle time. Pick it when the round head and magnetic-accessory ecosystem are more useful than the V100S’s additional output.
- V1Pro S is the Sony TTL version
- 76 Ws output with 28-105 mm zoom
- About 500 full-power flashes per charge
- 1.3-second recycle time supports active portrait work
- Round head accepts Godox round-head accessories
- 580 g with battery is still a substantial on-camera load
- It has lower maximum output than the V100S
Godox V480S
The V480S is a current Sony version with GN 50 at 105 mm, a 2 W LED modeling lamp and a smaller 2200 mAh battery. Godox rates it for about 650 full-power flashes and 1.7-second recycling. Firmware V1.03 was issued in February 2026, which is a useful sign of current support for this model.
- V480S has GN 50 at ISO 100 and 105 mm
- 7.2 V 2200 mAh lithium battery
- February 2026 V1.03 firmware release
- About 361 g with battery is lighter than V1Pro S or V100S
- Sony global-shutter sync support is specified for V480S
- Lower-capacity battery than the 2980 mAh V1Pro and V100 packs
- Accessories use the S3 bracket rather than a built-in round head
Godox V860III-S
The V860III-S is the established full-size rectangular Godox lithium-ion flash for Sony TTL cameras. Its 7.2 V 2980 mAh pack, 2 W modeling lamp and 2.4 GHz radio make it a practical bridge between an older Godox X setup and the a7R IV. Allow cooling breaks in repeated full-power or HSS work because the manual documents thermal protection.
- Sony TTL model V860III-S
- 7.2 V 2980 mAh lithium-ion battery
- Godox 2.4 GHz radio transmitter and receiver roles
- Rechargeable pack avoids managing several AA cells
- Existing V860III firmware and manual remain available from Godox
- Thermal protection can slow recycling after rapid repeated firing
- Rectangular head does not take V1Pro round-head magnetic modifiers directly
Godox TT685II-S
Godox’s TT685II-S is the AA-powered Sony-TTL route for photographers who prefer readily available cells. It remains part of Godox’s TT685II C/N/S/F/O line and has an official Sony-specific manual. The key buying distinction is power source: it avoids proprietary battery packs but needs four AA cells and a charger for serious event work.
- Sony-specific model is TT685II-S
- Four AA cells power the flash
- Godox provides a TT685II-S compatibility manual
- AA power can be replaced quickly on location
- Godox X system compatibility supports off-camera expansion
- Four cells and charger add ongoing consumable management
- AA recycling usually trails lithium-ion speedlights during heavy use
Godox TT350S
The TT350S is Godox’s small Sony-TTL speedlight for a lightweight a7R IV carry kit. Its compact format and 2.4 GHz X radio make it useful as a controller or modest fill flash, but it gives up the headroom of the V860III-S and V480S. Use it for direct flash, close bounce or travel instead of expecting it to light a large hall.
- Sony TTL version is TT350S
- Compact speedlight body for smaller kits
- Godox 2.4 GHz X-system radio
- Small body balances better on a travel setup
- Can join the same Godox radio lighting system as larger flashes
- Lower output limits high-ceiling bounce work
- Compact batteries provide fewer reserve flashes than V-series packs
Godox iT30Pro S
The iT30Pro S is the miniature Sony-TTL flash for photographers who prioritize a nearly pocketable on-camera unit. Godox specifies flash duration from 1/1000 to 1/30000 second, and its hot-shoe format is suited to casual direct fill rather than large soft bounced light. It is the least imposing option here, but also the one with the least flexibility for event lighting.
- Sony TTL model iT30Pro S
- Flash duration from 1/1000 to 1/30000 second
- Mini hot-shoe flash format
- Tiny format keeps the a7R IV kit unobtrusive
- Short flash durations help when freezing nearby movement
- Small head is poorly suited to broad ceiling bounce
- Mini form factor offers less power reserve than a full speedlight
Buying tips
- Buy the Sony S version of a Godox flash.
- Check TTL and HSS support for the a7R IV.
- Use a higher guide number for bounce work.
- Price batteries and chargers with the flash.
- Test radio triggering before an event.
- Use an external trigger for off-camera placement.
