Flash Synchronization Compatibility Matrix

You are here:

The table below outlines the supported combinations of flash synchronization mode, camera drive mode, and focus mode when using LA4 flash workflows. It highlights which flash modes are compatible in each scenario, as well as any important limitations or operational considerations.

 

In general, configurations that rely on Hotshoe Response provide the most reliable timing and widest compatibility. Setups without Hotshoe Response require manually configured delays and are limited to specific workflows. Particular attention should be paid to autofocus modes when using multi-image flash sequences (such as OLAT and ALL+PALL), as the camera may refocus between exposures, resulting in inconsistent focus planes across captured images.

 

Use this matrix to determine the recommended camera settings for your workflow and to identify combinations that may lead to unreliable triggering, timing inconsistencies, or unsupported operation.

Flash Sync Drive Mode Focus Mode Compatible LA4 Flash Modes
Hotshoe Response
Single
MF
All modes ✔️
Hotshoe Response
Single
AF-S/AF-C
ALL, N_LIGHTS only. Camera focuses between shots when using a multiple image flash mode i.e. OLAT, ALL+PALL. The focus plane is inconsistent between shots. ⚠️
Hotshoe Response
Continuous
MF/AF-S
All modes ✔️ With AF-S the camera only focuses once at the beginning of a sequence, including multi-image flash modes i.e. OLAT, ALL+PALL.
Hotshoe Response
Continuous
AF-C
ALL, N_LIGHTS only. Camera focuses between shots when using a multiple image flash mode i.e. OLAT, ALL+PALL. The focus plane is inconsistent between shots. ⚠️
NO Hotshoe Response
Single
MF
All modes ✔️ However, custom delays need to be specified (shutter press, shutter lag, light duration and post-shot).
NO Hotshoe Response
Single
AF-S/AF-C
❌ Incompatible. Focus time varies and no delays are consistent between shots.
NO Hotshoe Response
Continuous
MF/AF-S/AF-C
❌ Incompatible. Delays between images are never consistent and custom delays do not work correctly.
