The much anticipated, all-new Cactus Wireless Flash Trigger System V4 is here! This new flash trigger system is a significant upgrade from all current and previous Cactus wireless flash trigger versions. The new version gives photographers even greater creative control over lighting in their images.

With the new Cactus Wireless Flash Trigger System V4, you can place multiple flashes at various angles and distances from your subject. This is particularly useful for portrait and product photography. Each receiver works with one flash. You can use as many receivers as you wish, all receiving their signal from one transmitter. Simply attach the hot shoe of the external flash to that of the receiver, or use the flash connection cable. Most importantly, without the need to connect the flash to your camera by hot shoe or cable, you can move the flash to anywhere that produces the best lighting on your subject. With the flexibility the new Cactus V4 triggers provide, the possibilities are endless!

The innovative standing design allows all the common portable flash units to sit securely on it without a separate light stand. When shutter is released, the receiver picks up on the signal emitted from the transmitter on your camera and will trigger the external flash connected to it. The fastest response time is 1/1000s (actual sync speed varies from 1/125s to 1/600s depending on the sync speed limit of the camera system).

The Cactus V4 offers many improved features over the V2 version. These improvements include a new antenna design that increases the reliability and effective distance to 30 meters(about 100 feet) and a new power source: AAA batteries. The 16 selectable channels and advanced anti-interference feature will allow the device to work within the effective area without interference from other devices. This new Cactus version offers a high degree of compatibility. With the provided connection cables, photographers can use the receiver with a range of lighting sources including low trigger voltage portable flashes, high trigger voltage portable flashes and studio strobes.


A complimentary copy of the photo album, "When Light Dances" is included in the package. Wonderful pictures taken by photographers using the new and improved Cactus V4 radio trigger system, as well as setup details are shown for your reference.


Compatible With:
Cactus V4 does not work with V2s or V2;
Cactus V4 does not transmit TTL information.
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.
