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.(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.)
Two High-Speed Sync Modes:
Normal HSS: Supports shutter speed up to 1/8,000s.
Power Sync: Boosts flash contribution above camera's x-sync speed, perfect for extreme conditions where Normal HSS is not powerful enough. (Power Sync may require the user to adjust the sync time in order to eliminate any banding issues (black line across the image).)
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! (AF-assist works when the camera sends out a corresponding signal.) 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 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. (To auto-detect camera system, half-press the shutter release of camera while switching on the V6 II to TX mode.) 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.
