645DF+ / IQ280 / 120mm Macro Flash Sync

Postby The_EL » Wed Feb 18, 2015 7:54 pm

Hey all,

First post here. Im having issues syncing above 125th with this combination. (645DF+ / IQ280 / 120mm Macro)
I also have the 55mm and 80mm on hand and they are syncing fine at any speed. I know they are leaf shutter lenses and the 120 is not but I would image it would at least sync to 200?

Any help would be greatly appreciated.

This is to specification.
Lenses relying on focal plane shutter can only be sync'ed to 1/125th.
