Seduced by the 1/1600th flash sync of the new Phase One 645DF, leaf shutter lenses and p40+ back, I bit the bullet and picked mine up yesterday.
And to my surprise, I can only make it sync properly at 1/400th or below. At that speed, all is good. Above it, it's not.
I'm using Elinchrom Ranger Quadras. I have tried both the A head and S-head (A has shorter duration), and both Elinchrom Skyport triggers and Pocket Wizards, and the same result.
If I take the fast A "Action" head, and plug it into the B socket (only one third power but faster ie shorter flash duration) then it will sync at up to 1/800th with significant loss of power. And having lots of power to overpower the sun is precisely why you want high speed flash sync in the first place! This makes it useless outdoors.
I've searched Phase forums and this one to see if anyone else has had the same problems...
Phase One forum says someone else has the same as me when using Profoto flash.The Phase One anser says suggests the flash duration on what it calls "cheaper"! flashes can be too long!
So I tried it with a Nikon SB800, which obviously has a short duration, and there's no joy with that either. Same result... well, it sort of syncs at 500th only if you have the flash on full power, but is pretty dark. In reality it's 400th or below.
Please, please someone tell me am I a total fool and am doing something wrong and just need to change a setting! I have read the user manual twice and can't seem to see what I'm doing wrong. Help!
I really hope this isn't an 18,000 Euro mistake!
Yes, I have emailed Phase...
