Messing about with this lovely new (to me) flash, for which I have not yet paid, I’m a little confused. Flash is in full native communication mode, both camera and flash are Olympus. I select auto ttl, and with my Sigma F1.4 lens it seems to default to widest aperture and everything is very over exposed.
So I put the camera in A mode and adjust the aperture. The distance reading on the flash changes, so it knows what aperture is selected, but when I take pictures at different apertures they seem differently exposed. They SHOULD all look broadly the same, no? Is that not the whole point of TTL mode?
