Cactus Wireless Flash Transceiver V6 II

The Cactus V6 II is the World’s First wireless flash trigger that supports cross-brand high-speed sync (HSS) and can control power output and zoom angle of Canon, Fujifilm, Nikon, Olympus, Panasonic and Pentax system flashes all at the same time.1

Enter V6 II Microsite

Two High-Speed Sync Modes

  1. Normal HSS: Supports shutter speed up to 1/8000s.
  2. Power Sync: Boosts flash contribution above camera’s x-sync speed, perfect for extreme conditions where Normal HSS is not powerful enough.2

Cactus also extends HSS capabilities to Fujifilm cameras despite them not yet supporting high-speed sync at the time of writing.


Both the V6 II and IIs now has an automatic LED AF-assist light that makes auto-focusing in dark environments possible – even in pitched-black!3 Besides the camera-mounted V6 II/IIs, off-camera units will also activate the AF-assist light, which helps focusing even when camera is far from the subject.

Highly Intelligent

V6 II can now auto-detect the on-camera portable flashes at device start-up by selecting the system the flash belongs to and assigning an Auto flash profile. Moreover, it now works with previously unsupported digital-only TTL flash models on the V6 and expands its compatibility.  Similarly, the V6 II will auto-detect the camera and selects the system accordingly.4  This simple plug-and-play makes the setting up extremely quick and easy that both amateurs and professionals appreciate.

Flash Profile Customization

Users may still manually choose from more than 60 popular flash models from Canon, Nikon, Pentax, Olympus, Panasonic, Metz, Nissin, etc. should they wish to. And for those who demands the utmost accurate power outputs they may adjust each power level using the Cactus Profile Editor, a computer-installed software that allows the saving of up to 10 personalized flash profiles.

Remote Power and Zoom Control

Besides remote power control, remote zoom control is now available to all compatible TTL flashes, which was only available on Cactus RF60 series Wireless Flash before. This will give photographers much quicker controls by swapping controls of power and zoom settings directly on the V6 II.


The V6 II now allows multiple photographers to trigger off-camera flashes at the same time. Not only is this great for wedding and events, it is also perfect for running photography workshops.

Notes on compatibility:

  • Cactus V6 II is not compatible with Cactus V6 on firmware version 1.1xxx. Update to the latest firmware (version 2.1.001) on the V6 and the V6 II will be backward-compatible under camera’s x-sync speed;
  • Cactus V6 (RX) does not support Normal HSS when triggered by the V6 II;
  • • Cactus V6 (RX) supports Power Sync by updating to the latest firmware (version 2.1.001) when triggered by the V6 II;
  • Cactus RF60 (RX) supports Normal HSS and Power Sync by updating to new firmware (version 200 and onwards) when triggered by the V6 II;
  • Cactus V6 II does not work with any other flash trigger model including Cactus V4, V2s or V2;
  • Cactus V6 II does not transmit TTL information wirelessly;
  • Cactus V6 II is not compatible with flashes or strobes with reversed polarity connectors;
  • Cactus V6 II is compatible with practically all cameras that come with either (1) a standard ISO hot shoe, or (2) a female sync port connection;
  • Cactus V6 II is compatible with the Wireless Flash Transceiver V5 and Laser Trigger LV5 for basic flash triggering and shutter release.
  • Camera(s) tested that does not support high-speed sync modes on the Cactus V6 II:
      - Fujifilm X-E2 (Updated: July 18, 2016)
      - Fujifilm X100T (Updated: September 7, 2016)
  • Cactus V6 II is compatible with the Olympus O-MD E-M1. However, some copies of the E-M1 come with a thicker-than-usual metal hot shoe spring plate which has to be removed when working with the V6 II. Check out how to remove the spring plate in this discussion forum thread. (Updated: August 5, 2016)
  • Cactus V6 II is compatible with the Panasonic Lumix DMC-GX8. However, due to special timing requirements by the camera it only supports HSS up to 1/4,000s. (Updated: September 1, 2016)

1 With the exception of Pentax system flashes due to special timing requirements so it must be paired with a Pentax camera in order to support HSS.

2 Power Sync may require the user to adjust the sync time in order to eliminate any banding issues (black line across the image).

3 AF-assist works when the camera sends out a corresponding signal.

4 To auto-detect camera system, half-press the shutter release of camera while switching on the V6 II to TX mode.
