What Is X-Sync?Updated 12 days ago
X-sync is a simplistic flash synchronization mode that fires your strobe at the exact moment your camera’s shutter is fully open within normal sync speeds.
Most Westcott FJ strobes and triggers support X-sync and will allow exposures up to your camera’s native sync speed, usually around 1/200s to 1/250s. Beyond this speed, you risk partial exposures unless you switch to High-Speed Sync.
- X-Sync must be OFF to enable HSS and TTL
- HSS and TTL will be disabled when X-Sync is enabled
- X-Sync is ideal for film photography.
How does X-sync work with my camera?
X-sync uses the camera’s center hot shoe pin to trigger the flash at the moment the shutter is fully open.
Westcott triggers and speedlights offer the X-sync mode and is designed to be compatible across camera brands, including film cameras. When using X-Sync mode, the trigger communicates via the center pin only, disabling TTL and HSS features for universal, manual control.
When should I use X-sync be used?
X-Sync can be used for film cameras, cameras not listed on Westcotts compatibility list, or as a troubleshooting tool to assist in diagnosing TTL issues.
Sometimes, when triggers or speedlights are not aligned properly on a camera's hot shoe or when used on a camera that has not been tested by Westcott, flashes may not fire or sync with the shutter. In this instance, X-Sync can be used as it disables the TTL connections, only allowing for center pin firing.
Use X-sync when shooting at or below your camera’s native flash sync speed, usually up to 1/250s, for proper synchronization.
What is the X-sync speed on my camera?
The X-sync speed is the fastest shutter speed your camera can use while still exposing the full frame during a single flash burst, typically 1/200s to 1/250s. Some cameras will have an X next to the shutter speed that is the max sync speed.
Exceeding this limit without enabling HSS can result in black bands or partial exposure. Always check your camera's manual or the Westcott compatibility chart for exact values.
Does X-sync affect image quality?
No, X-sync does not reduce image quality; it simply allows for the simple, center pin firing of the flash. It does disable TTL and HSS features.
