Cactus V4 Wireless Flash Trigger Set

Usually ships in 2 business days.

Product Description

With the Cactus Wireless Flash Trigger System V4, you can place multiple flashes at various angles and distances from your subject. When shutter is released, the receiver picks up on the signal emitted from the transmitter on your camera which will trigger the external flash connected to the receiver. The innovative standing design allows all the common portable flash units to sit securely on it without a separate light stand.

The transmitter weighed at only 33g and receiver 60g, Cactus V4 is possibly the most versatile flash trigger set you need.


Cactus Wireless Flash Trigger Set V4
Notes on compatibility:

  1. Cactus V4 does not work with V2s or V2.
  2. Cactus V4 does not transmit TTL information.
  3. Some dedicated flashes (e.g. Nissin Di-622 and Di-466, Sunpak PZ42x and PZ30, Sigma EF-530/500 DG ST for Canon, etc.) are triggered via system-specific pins instead of the central contact of the hot shoe. Cactus V4 does not work with these flash models. To check whether your dedicated flash units are compatible with Cactus V4, try attaching them to a camera of other brand (e.g. attaching a Nikon TTL flash to a Canon DSLR camera). If the flash can be triggered, it will work with Cactus V4.

All Cactus V4 sent after 21 June 2010 should no longer cause banding issues with Canon EOS 5D or Panasonic Lumix DMC-G1).
