XE-1 Flash issues at studio shooting
I have an X-E1 and at first had the same problem with the v/f being too dark, shooting low-key. The disable manual exposure preview was part of a f/w upgrade, and I dodnt even know about it until someone else mentioned it on the Fuji X forum. What a difference!
Now what is needed in a future f/w upgrade is to be able to shoot at the max 1/180 sync speed. Right now 1/160 is as fast as we dial in without clipping part of the frame at 1/200, the next setting. I informed Fuji about this, hopefully they are listening. If history is any indicator, they are.
Good luck, I really enjoy using my X-E1 and the Zeiss 32 F1.8 and the Fujinon 18-55 in the studio with my Buff lights, esp. the B&W film sims, just fabulous!
