JJC JSYK 3A Optical Slave Trigger (Alleen voor Canon)

The JJC JSYK-3A optical slave trigger is a specialized remote shutter release accessory designed exclusively for Canon camera systems. This optical slave unit functions by detecting the flash from a master flash unit or camera flash, then triggering the connected camera shutter instantly and wirelessly. With a compact design measuring approximately 60 mm in length, 40 mm in width, and 25 mm in height, and weighing about 45 g, this lightweight accessory offers convenient portability for photographers. The device operates on a standard 3 V CR2 lithium battery, providing reliable performance for extended shooting sessions.

Featuring a standard 2.5 mm sync port for connection to compatible Canon cameras, the JSYK-3A supports multiple flash modes including manual, TTL, and rear-curtain sync when used with appropriate camera settings. The optical sensor has an effective detection range of up to 15 meters under typical indoor lighting conditions, with a response time of less than 1/1000 second for precise synchronization. Constructed with durable ABS plastic housing and metal connector components, this slave trigger maintains consistent performance across various shooting environments.

The unit includes a standard hot shoe mount for secure attachment to camera flash brackets or light stands, along with a 30 cm sync cable for direct camera connection when needed. Compatible with most Canon DSLR and mirrorless camera models that support external flash synchronization, this optical slave trigger enables creative lighting setups for studio photography, portrait sessions, and event coverage. The device automatically enters power-saving mode after 30 minutes of inactivity to conserve battery life. With its straightforward operation requiring no complex setup or wireless pairing, the JJC JSYK-3A provides photographers with a reliable solution for expanding their lighting capabilities while maintaining full creative control over exposure settings.
