The Cactus is a world first: A wireless flash transmitter compatible with any camera with a hotshoe or PC Sync port, able to control the power output of Nikon, Canon and Pentax flashes (Olympus and Panasonic now added via firmware update) - or any combination of them - simultaneously. It's an inventive design and great value for money, to boot. You need a minimum of two V6 units, one to act as a Transmitter and a second as a Receiver to trigger and remote power control of one flash unit, unless you have a Cactus RF60 Flashgun which has a built-in transceiver. Additional V6 units can be added to control extra flashguns.

The Key Features:

  • Wireless manual power control of a list of current and previous Canon, Nikon and Pentax flashes (Olympus and Panasonic now included via firmware update at
  • Flash profile learning for analogue-TTL flashes
  • Full manipulation of power levels to 1/10, 1/3, 1/2 and 1EV steps
  • Lo Power mode fires the flash for extremely short lengths of time
  • Absolute Power Mode benchmarks the power output of different flash models to the same light intensity
  • TTL pass-through with Canon, Nikon, Olympus, Panasonic, Pentax, and Fujifilm via one single unit
  • Built-in optical trigger enables pre-flash triggering
  • Group control allows you to control up to four groups
  • Relay mode triggers the camera shutter and flash in sync
  • Delay timer is configurable from 1 millisecond to 10 seconds
  • Mini-USB port for optional power supply and firmware updates

Remote Power Control of Canon, Nikon and Pentax flashes (Olympus and Panasonic via firmware update at
Each flash model has its individual power level characteristics. Cactus have profiled more than 30 popular flash models across a wide range of brands so that the V6 can precisely control their output levels. With this unique feature, photographers can remotely control the flash power of various flash models, even of different brands.

Currently, more than 30 popular flash models from Canon, Nikon, Pentax, Metz, Nissin, etc. have been profiled and pre-installed on the V6. By selecting the pre-installed flash model on the Cactus V6 the photographer can remotely control the flash power output of the selected flash model wirelessly through the Cactus V6.

If a flash model is not listed, the V6 may even learn its flash profile and then be able to control the power output of the flash. (See note on compatibility)

Remote Power and Zoom Control of Cactus RF60 Wireless Flash
The V6 can directly control a Cactus RF60 set to Slave mode using RF60’s built-in radio transceiver. Besides controlling power remotely in single and multiple groups, the V6 can also adjust the zoom level of the RF60 easily by pressing the adjustment wheel and swap control between power and zoom.

Quick Power Adjustments
Control is extremely easy and swift with the use of a selection dial and a combination of group buttons. V6 can control multi-group power output in just one quick slide which is faster than any manual system available in market. To adjust an individual group, simply press and hold the group button and scroll the adjustment dial at the same time and changes will be instantly made on the V6 RX unit.

Absolute Power Control
V6 can benchmark the power output of flash models with different GN. In Absolute Power mode, EV numbers can be used to specify an absolute light intensity, independent of the maximum power output of a flash model.

V6 is so advanced and precise that 0.1EV power level can be adjusted, even if the flash does not offer that option*.

*0.1EV increment applies to certain flash models only. Please check the user manual for compatibility.

TTL Pass-through
The V6 transceiver comes with a multi-system shoe that supports TTL pass through. With TTL pass-through, the TTL flashes behave as they would when directly connected to the camera hot shoe.
