    Today I received my Godox TT350 and it works quite well.

    But I have a question which may or may not have to do with the brand of the flash.

    After playing for a while, with my PanaLeica 25/1.4,I observed that below f2.8 I get a reddish colour cast in the picture. F2.8 onwards (at least until 5.6) colour balance stays the same. So camera flat on table, flash straight up to white ceiling, pictures 1.4 - 5.6 without changing “composition”, just clicking to the next full stop and taking a picture. No exposure compensations on camera or flash, fixed flash white balance. TTL on flash.

    Any ideas ?

    Update: found out that if I dial in +1.3 on the flash while using 1.4 aperature the colour is the same. Seems that the software of the flashunit is reducing a lot of power when using an aperture below 2.8 ?
