The re-engineered and re-designed Cactus Wireless Flash Transceiver V5 (Cactus V5), like its predecessors, remain powerful and reliable, and is ideal for photography of any kind. It sports a new transceiver design and powered by 2 AAA 1.5V batteries, each Cactus V5 unit can serve as either a wireless flash transmitter or wireless flash receiver. Different transmitter/receiver combinations are now possible, giving photographers unparalleled flexibility and control over their Strobist setups.
Frequency Self-Tune (FST), a new and groundbreaking feature, enables Cactus V5 to automatically tune itself to its last working frequency when exposed to extreme weather conditions such as a sudden and large temperature change. Not seen in any other solution on the market, FST effectively minimizes "no fires".
Multi-Channel Triggering, another new feature, allows simultaneous triggering of up to four (4) sets of light sources, all controlled through one transmitting unit and camera. This is very useful in situations where multiple sets of flashes normally set to different channels need to be set off together for one or a series of shots.
Other improvements in Cactus V5 include support for any maximum sync speed supported by camera up to 1/1000s, working frequency of 2.4GHz, effective range up to 100 meters, implementation of a low battery indicator and 16-channel rotary dial for channel selection, and dual hot shoe design to allow concurrent firing of an on-camera flash. Together with the provided PC Sync and 3.5mm cables and 6.25mm plug adapter, photographers may use Cactus V5 with any** portable flash and studio strobe with trigger voltage up to 300V.
Each Cactus V5 unit is manufactured using RoHS compliant electronic components and parts.
**Notes on compatibility:
- Cactus V5 does not work with V4, V2s or V2;
- Cactus V5 does not transmit TTL information;
- Cactus V5 does not work with Canon ELAN 7E, 10D, 300D (Digital Rebel / Kiss Digital);
- Some dedicated flashes (e.g. Nissin Di-622 and Di-466 (Canon and Nikon dedicated versions), 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 V5 does not work with these flash models. To check whether your dedicated flash units are compatible with Cactus V5, 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 V5.
