Best Flash for Sony a6700
The Sony a6700 has no pop-up flash. Sony’s own sheet is a Multi Interface Shoe, α-system TTL, and a 1/160 s sync ceiling — slower than most full-frame bodies. Past that you need High-Speed Sync, not a bigger Guide Number sticker. Silent electronic shutter will not fire a speedlight on this sensor. The 2026 on-camera kit is a Godox V1S: Sony-foot TTL, 76 Ws, round head, 7.2 V / 2600 mAh pack, built-in 2.4 GHz X radio. It is not a $550 HVL-F60RM2 sold as the default APS-C flash.

How We Picked These Flashes
- What Sony published: ILCE-6700 spec: Multi Interface Shoe (Digital Audio Interface on the contacts), external flash is “Sony α System Flash compatible with Multi Interface Shoe,” flash sync 1/160 s, mechanical and electronic shutters, electronic front curtain on/off. There is no built-in flash line. Pre-flash TTL is the metering method. HSS is how you go past 1/160 — output drops because the tube pulses. Electronic / silent shutter on a non-stacked APS-C readout will not sync a xenon pop across the frame; stay on mechanical or EFCS when the flash is the point.
- The foot is the feature: TTL, HSS, FEC, and rear-curtain need a Sony-protocol foot — HVL-FxxRM or a Godox “S” body (V1S, V860III-S, TT350S). A Canon-foot V1C will sit in the shoe and still meter like a dumb manual gun. Godox 2.4 GHz X radio is built into these three; an XPro II-S / X3-S is for a second head, not a requirement for on-camera TTL. Sony’s radio system does not talk to Godox X — pick one ecosystem.
- The box you actually buy: Godox lists the V1S at 76 Ws, 28–105 mm coverage, 7.2 V / 2600 mAh, ~1.5 s recycle, ~480 full-power pops, 2 W LED model lamp, HSS to 1/8000. V860III-S is the same watt-second and battery class with a 20–200 mm rectangular zoom and a TCM switch. TT350S is GN 36 (ISO 100, 105 mm) on two AAs. Do not compare a V1 “GN 28 @ 50 mm” sticker to a V860 “GN 60 @ 200 mm” sticker as if they were the same test. Skip F60RM2 as the default — weather sealing and face-linked OEM TTL are real; $550 and four AAs on a 493 g APS-C body are the tax. Skip V1 Pro / V100 unless the bag already has that battery family and you will use the extra UI.
Best Flash for Sony a6700: Detailed Reviews
Godox V1S View on Amazon View on B&H
| Model | Godox V1S · Sony Multi Interface TTL |
|---|---|
| Output | 76 Ws · 28–105 mm zoom · ~1.5 s recycle · ~480 full-power pops (Godox) |
| Battery | 7.2 V / 2600 mAh Li-ion (VB26 family, shared with V860III) |
| On a6700 | 1/160 sync · HSS past that · mechanical / EFCS · not silent e-shutter |
| Buy this listing | V1S / V1-S. Not V1C, V1N, V1F. Not a “V1 kit” that is a Canon foot. |
Why it fits the a6700. The camera is small; the light still has to be a Sony conversation. V1S is that conversation plus a round head that feathers bounce instead of printing a rectangular hot spot on a ceiling. The lithium pack is why recycle stays near 1.5 s without a pocket of AAs. The 2 W LED is a modeling / AF helper, not a video key. Magnetics (AK-R1 dome, grid, gels) are the modifier story. It is top-heavy on a 16–50 or a 18–135 — two hands or a strap. 11 fps at 1/1 is not a speedlight job; drop to 1/16–1/32 if you need a burst. Firmware via USB-C when Godox posts an a6700-era update.
Skip this if you want the 200 mm zoom and TCM without the round head — V860III-S. Skip it if the flash lives in a jacket pocket — TT350S.
- Sony TTL / HSS on a lithium pack
- Round head + magnetic mods
- On-camera master for Godox X slaves
- Heavy on the a6700 shoe
- Zoom stops at 105 mm vs V860III

Godox V860III-S View on Amazon View on B&H
| Model | Godox V860III-S · rectangular VING |
|---|---|
| Output | GN commonly listed 60 m ISO 100 at 200 mm · 76 Ws class |
| Battery | Same 7.2 V / 2600 mAh pack as V1 — one spare serves both |
| TCM | TTL pop, flip to manual, keep the power |
| SKU trap | V860III-C / N, V860II (older VB18), V860IV if the listing is a different foot |
Why it fits the a6700. You give up the circular catchlight and the AK-R1 magnetics. You keep Sony TTL, HSS, 1.5 s-class recycle, and a zoom that actually tightens for a 70–350 on APS-C. TCM is the event move: let the camera meter once, then stop the exposure from drifting when a waiter walks through a bounce. Same X radio as the V1, so a mixed bag is fine. Plastic foot with a pin is the usual Godox note — lock the lever; do not treat it like a Sony metal claw.
Skip this if bounce quality is the point and V1S is within ~$30. Skip AA-era V860II unless the price is a real discount.
- VB26 + TCM + 200 mm zoom
- Usually cheaper than V1S
- Same radio family as the rest of a Godox bag
- Rectangular bounce is harsher
- No AK-R1 magnetic bayonet

Godox TT350S View on Amazon View on B&H
| Model | Godox TT350S Thinklite mini |
|---|---|
| Output | GN 36 (ISO 100, 105 mm) · 24–105 mm zoom |
| Power | 2× AA · recycle 0.1–2.2 s (NiMH is the adult choice) |
| Head | Tilt / ~270° swivel — not a full 360 rear bounce |
| On a6700 | The size match. Fill under a hat at 1/160 or HSS wide open. Not a dance-floor key. |
Why it fits the a6700. This body is a 493 g APS-C hybrid. A V1 on the shoe turns it into a flash with a camera attached. TT350S keeps TTL and HSS so daylight fill at f/1.8 is still possible, and it stays in a jacket. Two AAs are the limit: full-power recycle is slow, capacity is a convenience-store problem, and 2.4 GHz range is shorter than a V series. Godox also sells a V350S (same mini shell, lithium). That is a sidegrade if you already hate AAs; this row stays the AA kit because the price is why it is Budget.
Skip this if you are lighting a reception — V1S or V860III-S. Skip TT350C.
- TTL / HSS at travel weight
- Balances on the a6700
- X radio still there for a second head
- 2× AA recycle and capacity
- Incomplete rear swivel

If You Need Something Else
These two are not cheaper versions of the Top 3. One is the Sony flagship. One is the wrong-foot listing that shows up next to V1S.
Sony HVL-F60RM2 View on Amazon View on B&H
| Sony sheet | GN 60 · Quick Shift Bounce · radio commander · dust/moisture rated · 4× AA · ~439 g without cells |
|---|---|
| When it wins | Rain, dust, and you already own Sony radio flashes — not Godox X |
| On a6700 | Deepest MI-shoe talk (face-weighted TTL on Sony’s stack). Still 1/160 sync. |
F60RM2 is the flash if the camera is already a weather-sealed kit and the backup flash is also Sony. Quick Shift Bounce keeps the head orientation when you rotate to portrait — an event habit. Four AAs at this price are the 2026 complaint. It does not make the a6700 sync faster than 1/160. Do not buy it so “OEM” appears in a bag dump.
Skip this if the body is an a6700 and Godox already lights the rest of the job — V1S.

Godox V1C / non-Sony feet View on Amazon View on B&H
| Why they show up | “Godox V1” search without the S |
|---|---|
| V1C / V1N / TT685C | Canon or Nikon TTL. Mechanical fit is not protocol. |
| Vintage / high-voltage | Old studio guns can exceed what a modern MI shoe should see |
Same skip: Profoto A10 as the first a6700 speedlight, a Nikon optical SU-4 “universal” foot, and any listing that promises 1/8000 sync without HSS — that number is the HSS ceiling, not the a6700’s 1/160 x-sync. Electronic silent shutter plus flash is the other way to get a black frame.
Skip this if the camera is an a6700. Buy a V1S, a V860III-S, or a TT350S.

Frequently Asked Questions
What is the a6700 flash sync speed?
Sony lists 1/160 s. Faster shutters need HSS on a Sony-protocol flash; power falls off because the tube strobes through the slit. Do not treat 1/8000 on a Godox box as the camera’s x-sync.
Will flash work in silent / electronic shutter?
Plan on no. The a6700’s full electronic readout is not a stacked global reset. Use mechanical shutter or EFCS for xenon. Video is a continuous LED / Godox ML problem, not this speedlight page.
Do I need a Godox trigger on the camera?
Not for one V1S / V860III-S / TT350S in the shoe — that unit is the master. You need an X3-S or XPro II-S when the flash leaves the camera or you mix Sony OEM radio with nothing. Sony radio and Godox X do not share a protocol.
Why does burst mode miss flashes?
The a6700 can run 11 fps. A 76 Ws pack cannot refill at 1/1 that fast. Drop flash power, use the lithium models, or slow the drive. That is physics, not a defective V1S.
Final Verdict
For most a6700 kits, buy a Godox V1S, stay on mechanical or EFCS, and treat 1/160 as the sync wall unless HSS is on. Want the same battery without the round head? V860III-S. Want fill that does not outweigh the camera? TT350S. Skip the F60RM2 as the default, skip any Godox that is not an S foot, skip silent shutter plus flash. The camera never shipped a pop-up. The shoe is the flash.
