Hi All,

Has anybody ever seen one? I just got one, and it's quite neat.

Little circular-dial calculator. Calculates DoF, lensboard angle, and bellows extension f-stop compensation.

I would recommend you grab one if you have the opportunity.

Leigh,

Indeed they are, as I have one also.

Aparrently there was a Sinar version available at one time too.

Enjoy,

Len

Given that Rodenstock makes the lenses for Sinar, that certainly makes sense.

I wonder if it's exactly the same item, or perhaps modified in some way? Interesting.

Thanks for the info.

It's two-sided. This side does DoF and exposure comp, the other does Scheimpflug. Instructions are in German and English. It's about 8.5 cm wide, based on its own measuring scale. :D

Actually it did have a different form, but similar functionality.

I have never actually seen the Sinar one, but seem to remember a thread on this site about both of them that included an image of the Sinar one.
