| All references to TTL on this page refer exclusively to Canon's E-TTL II system, or Nikon's i-TTL/CLS.
Film TTL or earlier digital TTL systems are not supported.
|"Speedlite" and "Speedlight" are used interchangeably. Either may be used to refer to Nikon or Canon's hot shoe flashes. Nikon or Canon specific information will be noted as needed.|
|REMINDER: Speedlights mounted on a remote FlexTT5 should be set to their standard i-TTL/E-TTL mode. Do not use <MASTER>, <REMOTE> or <SLAVE> modes on a remote flash.|
