Speed Graphic flash sync?

[jvuokko]

Hi,

What Graflex Speed (4x5) models have a flash sync for focal plane shutter?

I have spent lot of time with google, but somehow I can't find enough information.


My Graflex is Anniversary - does it have flash sync for rear shutter? It would be really useful for barrel lens portraits..


Thanks,
Jukka

it seems that the focal plane shutter was only sync'd with bulbs ( #31 )
and at the slowest speed. for your camera it is either 30thS or 50thS.

if you have an electronic flash, not bulbs, it won't sync at all ...

you could always paint with light though ...
have the room dark, leave your shutter wide open
and burst light on your subject until it is illuminated.
you could use any sort of light source, from a flash light,
to an electronic flash, to a lantern on a stick ...

have fun with your portraits !

Right. no electronic flash with the focal plane shutter. A few aluminum work lights or brooding lights with big CFLs in them will provide plenty of continuous light for 400 speed film and 1/30th shooting at wider apertures.

It's a lot of money ($300 and up), but if you need x-sync, then mounting a copal-3 shutter to the front of your lens will get what you want. It could sometimes be done with filter ring adaptors and tape.

The 4x5 Anniversary Graphic has NO synch contacts on the focal plane shutter at all unless it has been modified.

I believe in 4x5 that would be the Pacemaker Speed Graphic. Anniversary did not come standard with FP sych and Crown does not have FP shutter... nor does the even later Super Graphic.

In the time exposure mode, the Pacemaker Speed Graphic flash contacts close after the shutter has completely opened. If the ambient light isn't too high, a fast finger can double click the shutter for electronic flash. The shutter slots are too narrow for basic electronic flash at higher shutter speeds. On an Anniversary model, a microswitch could be installed so the shutter wind key trips it, but this would be inconvenient.

Thank you.

I have one Packard shutter, I can modify it to trigger flashes, but it's not as convenient as FP shutter.

The two easiest solutions for you might be (1) using your Packard shutter, or (2) buying a Pacemaker Graphic camera.

Well, I'm wanting to use an electronic flash with my Speed Graphic Anniversary Edition, and I can't find any posts discussing the setup I have: no X, no F, no M - my 127mms Ektar lens gives me the choice of a "5" or "20" setting (I assume milliseconds). Any way I can turn this into a X sync? The adapter cord is not a problem, just the delay.
