Rodenstock Clarovid II Rangefinder (01)

Rodenstock Clarovid

German 6x9 folder for 120 type rollfilm. Produced around 1934.

This is the second model of the Clarovid where the rangefinder and viewfinder systems are united so it has only one viewfinder window on the back.

 

Here a view on the Rangefinder lay-out. This mechanism is supposed to have been engineered by Rodenstock themself. But guess that they were aided a bit by Welta which produced the body of this camera.

 

The linear movement of the lensboard is transfered by Pin #1 to a rotational movement of #2. Next this movement is transfered at #3 by a kind of cam-curve to the Mirror rotation.

 

The image catched by the rangefinder Window #4 is reflected by the (rotational) Mirror #5, passes through a small (stationary) Lens #6 and projected on a tiny Mirror #7 which is visible on the top and the middle of the viewfinder image.

 

The "normal" viewer image comes through the frontlens #8. Passes through a mask which also holds the tiny Mirror #7 and then goes through 3 prisms at #9 before it al last leaves the camera at the tiny peephole #10.

 

The rangefinder produces a completly separate, small rectangular image in the top/middle section of the viewfinder and the focus distance is Ok when that tiny image "fits" into the big viewfinder image.

 

A very elaborate system ! Guess they had to come up with something like this to avoid patents related claims from other camera manufactors
