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. Cactus V4 wireless flash transmitter (x1) and V4 receiver (x2)

This wireless slave flash trigger unit triggers other flash units when the transmitter is activated. Several flash units work together helps fill in shadows and improve the evenness of lighting.

Three components are included in this BUY IT NOW package, a transmitter and two receivers. The transmitter is to be attached on the hot shoe of the camera while the receivers are to be attached to external flashes. Each receiver works with one flash. You can use as many flashes as you wish as long as you have enough receivers.

With the wireless flash trigger, you can place the flashes at different angles and distances from the object. This is particularly useful for portrait and product photography. Most importantly, without the need to connect the flash by wire or cable, you can move the flashes to anywhere that produces the best lighting to the object you shoot. Flexibility provides you with the best result.

3. 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.

4. 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.
