120folder.com          S.E.T.R.I. (Ihagee Ultrix)

This is not a rangefinder, but it seems to be rare or all information got lost. The S.E.T.R.I. is a simple 120 film folding camera, 6x9 format, probably built in the 1920s or 1930s. I found no information either about the firm nor the camera. There are several firms with this name, but it's either house insulation or electrics.

Although there is an elaborate enamel sign for the brand and the lens is signed
S.E.T.R.I. as well, I think this is a re-branded camera. I have most probably found the origin. It could be an Ihagee camera from Dresden. Please have a look at a very interesting Dresden camera page. The link opens in a new window. At 2/3s of the page there are the Ultrix from 1922 36, this one seems to be a no. 1460 model. Lens type, shutter, body, focus system, it all seems to fit.

Handling a S.E.T.R.I. is easy, it's just like other folding cameras. Loading film is as usual. Open the camera back,
retract the film advance to liberate the cradle, swing the cradle out and put the take-up spool into place. Same procedure for the film spool. Insert the film paper backing into the take-up spool and advance it using the advance knob until it's well engaged. Close the camera back. Look at the red window and advance the film via the advance knob until the red window shows "1".

Open the camera bed.
Squeeze the two levers under the lens and extend the bellows. Set shutter speed and aperture. Set focus via the lever on the camera bed, focusing moves the bed out. Lower the shutter release lever. Moving the lever back cocks the shutter anew. That's it. To close the camera, set focus to infinity, squeeze the two levers under the lens and fold the bellows, press the hinges of the struts as usual, it will fold easily. Turn the film advance until the next number is shown.

S.E.T.R.I. is a nice and simple camera, easy to use, with a good lens and a reliable shutter. It lacks automatic film advance and a rangefinder, but it's a nice camera nevertheless. It's lightweight for a 6x9 camera. The origianal, the Ihagee Ultrix, is good choice if you want to start with a basic 6x9 120 film folder and spend next to nothing.
