This twin flash combo covers everything you need basically for outdoor portrait photography:

1. Cactus KF36 (x2)

Its vari-power of 1/2, 1/4 and 1/16 allows you to easily adjust the light intensity at your wish. Guide number is up to 120-ISO 100ft/ 36-DIN 21m. It has four auto f-stop settings and powerful automatic exposure range up to 70 feet.

Automatic Operation - Vari Sensor Module

This Cactus KF36 Electronic Flash has a Vari Sensor Module that measures the light reflected from the subject, as well as other reflective surfaces near the subject.

Calculator Dial

The Calculator Dial, though not electronically connected to the flash, is a convenient built-in-guide for determining flash exposures.

Sufficient Light Indicator

The Sufficient Light Indicator will let you know whether the light output is sufficient for a proper exposure before you take a picture.

Zoom and Bounce

You can tilt the flash head at 0°, 45°, 60°, 75° or 90°.

Thyristor Circuit

This energy-saving thyristor circuit of the flash saves excess energy for proper exposure which enables very fast recycling time.

2. Flash Diffuser (x2)

Flash units produce a harsh light, even when you use it with the little plastic built-in diffusers / reflector of the flash. To work close to a subject, you might need to soften this light. Two flash diffusers in this BUY IT NOW package (one for each flash) are here to help. Flash diffusers not only diffuse the light, they spread the light as well. It reduces the maximum working distance between your flash and the object. You can use this diffuser simply by fitting it in the flash head direct.

3. Flash Rotate Flash Bracket w/ 90 degree flash rotate (x1)

The U-shaped flash bracket is a perfect assistance in holding the external flash in a certain distance with the camera. This is to prevent the direct flash to be produced by placing the flash unit on the camera's hot shoe. With the help of the bracket, the flash unit could be positioned a bit higher than the camera or the either side of the camera to produce fill flash and bounce flash without the need of an assistance.

4. Cactus Wireless Flash Transceiver V5 Duo (x1) and V5 Single (x1)

The totally re-engineered and re-designed Cactus Wireless Flash Transceiver V5 (Cactus V5). Like its predecessors, Cactus V5 remains powerful and reliable, and is ideal for photography of any kind.

Sporting 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".

Moreover, Multi-Channel Triggering 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 under 300V or under.

Each Cactus Wireless Flash Transceiver V5 Duo package includes two flash stands and a complimentary copy of “When Light Dances 2”. This latest edition of our photo album features 18 photographs taken by talented photographers from around the world using Cactus V4 triggers.

** 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.
