I took a chance & bid on/won an as-is Sunpak 544, with no bracket, untested.
If I'm lucky, it wasn't tested because someone lost the bracket.
I'll know a little more when I get it...
...I'm hoping someone can clarify for me what options/requirenments there are to use it on various orphan cameras (modified Polaroid rollfilm-ers and Cg/SG Graflex).
From what I can figure out from web searches, it looks like it has a 1/4-20 mount at the bottom, and some sort of 'audio' connector, 2 or 3 conductor 'phone' jack (1/8" or 1/4"?)on the bracket mates with the flash.
I believe it is a 544 and not a 'D' dedicated model.
I read about flash for 35mm vs MF...and even flash for wide angle...
What difference does a flash make for MF vs 35mm, other than mounting bracket? Wide angle lens maybe needs wide illumination?
