70mm rollfilm back

[colin turner]

anyone know of a 70mm rollfilm holder to fit a 5x4" Sinar and deliver 6x12 negs?

You might have to have an old 70mm back refitted... but if you find some commercially available, I would love to get one myself!!!

Before investing in such a project, see if the film you want is available. There aren't many films left in 70mm--mostly color neg portrait films and B&W aerial films.

I have one, well almost. The width of the negative is 108mm instead of 112mm (Horseman 612) or 120mm (Linhof 612).

I got it on ebay in early March. It is a modified (It formerly used 3.5-inch roll film) panorama back, made by Keith. It has a counter that let's you know how many shots you've taken. It takes up to 100' of 70mm film, and it weighs almost 5 pounds. It is light-tight enough for IR film, and it fits a Graflok (Universal) back.

I am not selling it, but I can explain how it was modified for 70mm if you ever find a Keith 3.5-inch roll film holder for "4 3/8 inches by 70mm." (It's really almost exactly 4 1/4 inches.) I can send you a jpeg of it, if you want to see.
