This Sonia Extended Range version has approximately 25% increased range over the standard Sonia optical slave (yellow end cap).

This optical slave has the proprietary Sunpak connector and pushes directly into the sync port of several Sunpak flash units (see list below).

This device will immediately fire a connected flash unit when another flash burst is detected.  This allows a remote flash to be fired without any connecting wires.

The triggering flash must not emit a pre-flash as this will prematurely fire the connected flash.

It requires no batteries or other power; it runs off the flash unit it is connected to.

Fits:

• Sunpak 383 and 333 and other Sunpak hotshoe flash units that have the Sunpak proprietary variant of the subminiphone sync port (2.5mm - 3 ⁄ 32")
• Sunpak 522 and 544
• Sunpak flash units fitted with the STD-1D modular flash foot
• Flash units other than Sunpak that have a subminiphone sync port (2.5mm - 3 ⁄ 32")

Please note: This optical Slave will NOT fit the Sunpak 555 or 611 with the HH sync connector.  For the Sunpak 555 and 611 see FlashZebra.Com Item #0256.

It is small, about ½ x ¾ x 1 inches.  The slave and circuitry is encased in solid resin, so it is extremely rugged.

Price: $12.00 + shipping
