Meniscus (soft) lens on an RB67

[Reinhold]

I just finished a 120mm f:2.1 Wollaston meniscus lens for a customer's 4x5 camera.
Someone asked about one for an RB67, but the RB mount is complex.
To show how the lens renders an image on 120 film, I lashed the lens onto my RB…
Here are three images taken at various apertures (and the rubber band lash-up).
The lens board is a hardboard clone of the common Linhof Technika board.
So the customer can use the lens on his RB, as well as his 4x5 camera.
A Packard shutter makes controlling exposure times simple.
The results were so pleasing that I'm starting to design an RB adapter for all of my LF lenses...

very impressive indeed!

Neat stuff, Rube Goldberg would be proud!

 

[Andrew O'Neill]

Cool! I might have to lash mine to my RB now!

Please keep us posted on the RB adaptors!

Designing an RB adapter is not simple, I'm still working on it…

In the meantime, here's an easy way to mount a lens to your RB with black vinyl electrical tape
In this example, the lens is on a hardboard clone of the common 96x99mm Technika board.
Thus it'll work on lots of 4x5's as well as any RB67.

One way I've put odd lenses onto my RZ is to take an RZ lens with a functional shutter but damaged/fungused optics and gut the lens. Cut the barrel just in front of the forward-most part containing shutter bits and then stick your Franken-lens on the front of what's left. The only restriction is that the lens has to have a long enough distance from the rear of the lens to the image that it's long enough to "reach through" the camera and focus on the film.

I've considered mounting shorter lenses behind the shutter in this configuration but I've never worked out how to be absolutely 100% sure there's no risk of the mirror striking the back of the lens once focused.
