IR and bellows

[Shootar401]

Can anyone tell me if the bellows on either a Speed Pacemaker, Super Graphic or a Horseman standard and wide angle bellows are IR tight? I'm shooing a bunch of IR this summer and want to take out the right camera.

The Super Graphic is IR-tight, and so is the Toyo 45AX. The best thing to do is test a few sheets. It will be obvious if there's a problem with what you have.
