I have two speedlites. A Phottix Mitros and a Sunpak PZ42X. I can control flash intensity in both of them in TTL mode. I can also control the zoom (for Mitros it works, a bit buggy with Sunpak; whenever I try to set zoom in Sunpak it resets to what is previously set in the speedlite).
However, when I switch to manual mode, I cannot control the flash intensity for the Mitros. It might not be compatible with Sunpak but it's supposed to just work with the Mitros.
What could I be doing wrong?
PS: I do not know much about flash.
I am controlling the speedlites wirelessly via a set of Odin 2 transmitter and receivers. I am using the Odin 2 transmitter to adjust the flash intensity and zoom and to switch between TTL and Manual.
