i am using a superspeed, everything is working great, but i cannot get my flash to synch at the fastest speeds. i use the shutter release, everything (including the flash) fires, but the polaroid is black. I have gotten an image at 1/2 second shutterspeed, I am not sure if there is a delay in the shutter or in the flash-trigger, don't know how to find out. please help, thanks. |

We ought to be able to figure this out.
In the subject, you mention electronic flash. Assuming that's what you're using, tell us how you set up for a flash picture.
Are you connecting your flash connection cord directly to the front shutter? Is the connection on the shutter a "bi-post" connection [that is, does the shutter have two posts which plug directly into your cord?]. Most importantly, does that shutter have an "X" setting, and are you using that setting? |

the connection is on the side of the body. it is a 3 prong graflex socket. here i plug in a 3 prong graflex to 2 prong household cord which goes into a household female to pc female which goes into a male pc to male pc cord which goes into my IR trigger which fires the flash. the lens has 2 settings X,M according to the manual the M setting is for graflex flashes and others up to 1/500, the X for anything faster. i have tried both settings on various times, no difference(that i can tell). i will order a synchcord from paramount to cut the distance but that should not be a problem anyway. the flash fires, the shutter fires, but i cannot tell if it fires before or after the shutter opens. considering i had some luck with a 1/2 sec exposure, i am assuming it fires after the shutter opens. could it be that there is an electronic delay, so by the time the flash is triggered the shutter has already closed again? |

Yikes - that's a lot of connections and electronics to hope to sync to. First, if you want to sync the shutter to the electronic, ONLY use the X setting. You'll ALWAYS get a delay with it set on M.
Could the IR be interjecting a delay? Have you tried connecting the flash directly (w/o the IR?), that is the cord from the 3 prong connection directly to the flash? Or, do you have a battery case for that camera? If so, plug the household plug from the 3 prong connection into the battery case, and plug the electronic flash into the "extension" outlet of the case. Either of those direct connections, coupled with using the X setting of the shutter, should yield a synced shot. If not, perhaps there's a problem with the shutter itself. Some were converted to sync ONLY to bulbs, while others were changed to sync ONLY to elec. flash. You might have one of the former. |
