The Plank 75mm V1.3.2 jb76853

The Plank is finally finished-

 

Now featuring retaining clips for roll film holders and Polaroid backs,

and improved light traps and seals. The viewfinder housing has been slimmed down too-

 

However, the main difference is in the lens-

I managed to find a 75mm glass bi-convex lens in a jewelers loupe set in a tool shop, which was just oversized-

a little bit of grinding allowed it to fit in the shutter-

 

Lenses can be exchanged relatively easily;

the Super Angulon cells unscrew and are replaced by the single 75mm element, which is held in place by two O rings.

 

There is some mechanical vignetting due to the extra length,

so this one will be mostly used with the 6x9 back,

although it very nearly covers 6x12, so I'll be using that one too-

 

It just about covers a Fuji instant, and the print from a Polaroid,

but doesn't cover a complete 4x5 neg-
