Off-Camera Coiled Sync Cord with Integrated Low-Light Autofocus Illuminator
The Nikon SC-29 is a premium, high-performance off-camera flash synchronization cord designed to provide complete, uncompromised i-TTL exposure control for Nikon Speedlights. Measuring 3 feet long when coiled and expanding up to 9 feet, this heavy-duty cable allows photographers to remove their flash from the camera’s hot shoe to sculpt dynamic, off-axis lighting profiles. It is an indispensable accessory for portrait artists, wedding documentarians, and event photographers who utilize flash brackets to eliminate harsh shadows and red-eye.
Setting itself apart from standard sync cords, the SC-29 features a built-in infrared AF Assist Illuminator on the hot-shoe mount module. This integrated emitter replaces the camera’s native autofocus lamp, casting a helpful focus grid directly onto your subject to ensure rapid, pin-sharp autofocus acquisition in pitch-black or low-contrast environments.
Advanced Flash Support & Refined Mechanical Handling
Uncompromised i-TTL Telemetry: Fully supports all advanced Nikon Creative Lighting System (CLS) functions, matrix metering data, and high-speed sync modes, acting as a seamless, lag-free electronic bridge between your camera body and flash.
Integrated AF Assist Module: Features an onboard infrared focus-assist lamp on the shoe portion that slides onto the camera. This ensures your camera can still lock focus instantly in low light, even when the actual flash unit is positioned far off-camera or aimed backward into a bounce reflector.
Parallel Camera Shoe Connection: Features an updated ergonomic layout where the heavy-duty cable exits the camera hot-shoe block parallel to the camera body rather than sticking straight up. This low-profile orientation clears your field of view and keeps the cord from draping clumsily over the viewfinder or lens barrel.
Dual Posi-Lock Security System: Outfitted with an improved, secure Posi-Lock mechanical sliding latch switch at both ends of the cable. This locking system guarantees that neither the camera-side module nor the flash-side shoe will accidentally slide off or lose electronic pin contact during heavy, fast-paced event assignments.
