EOS 7D Mark II: flash control

To quickly access the flash menu settings when using an external Speedlite, you can press the Flash button that is normally used to raise the built-in flash. This gives you access to most of the flash controls. However, there are three that are missing: Flash Firing, ETTL metering and Flash Sync Speed in Av mode. If you need to access these settings, you should instead reach the flash menu from the main menu settings and select Flash Control.
