Cactus launches V6 IIs HSS Wireless Sony Flash Transceiver


Cactus V6 IIs HSS Wireless Flash Transceivers for Sony MI Shoe ($95 at B&H Photo) join the quickly growing list of wireless flash triggers supporting High-Speed Synchronization on Sony cameras. I have not had a chance to try this one out – but it looks interesting. Please note that while Cactus’ press release mentions Focus Assist – external focus assist lights are normally NOT compatible with mirrorless cameras, so don’t hold your breath on that one. Please Note: this is a transceiver which means you need one unit for the camera and one additional transceiver for each flash you wish to fire.

Press Release:

Go high-speed sync! Cactus launches the V6 II, a newest version of its popular Wireless Flash Transceiver to add cross-brand HSS and the V6 IIs, a dedicated Sony version.

After two years in the making, Cactus V6 II & IIs – the second generation of the World’s First cross-brand wireless flash transceiver, now supports high-speed synchronization (HSS)

Besides the revolutionary remote power control of Canon, Fujifilm, Nikon, Olympus, Panasonic and Pentax flashes all at the same time, the new models now support HSS / FP mode in the same cross-brand environment. This unique function gives photographers flexibility undreamed of. Matching flashes with same camera system for off-camera flash photography is over.

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.

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 autofocusing in dark environments possible – even in pitched-black! 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.

V6 IIs for Sony

The dedicated Sony version – V6 IIs, embodies all the desirable functions of its sibling V6 II but with a Sony compatible hot shoe on the transceiver body, ensuring a seamless and secured connection with Sony cameras and flashes. Mounting the V6 IIs on a Sony Alpha camera allows the photographer to shoot above camera’s maximum x-sync speed and control power and zoom of Sony, including those with a Minolta/Sony hot shoe via an adapter, and other V6 II compatible flashes. It is the perfect wireless flash trigger for existing and new users of Sony Alpha cameras, especially those who may still have non-Sony system flashes in their camera bags.

Highly Intelligent

V6 II and IIs 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. Similarly, the V6 II will auto-detect the camera and selects the system accordingly. This simple plug-and-play makes the setting up extremely quick and easy that both amateurs and professionals appreciate.

Expands Flash Compatibility

Remote zoom control now applies to all compatible TTL flashes, gives the photographer much quicker controls. Better still, previously unsupported digital TTL flash models on the V6 are now being supported.
