I'm selling my Heidoscop Stereo Camera, serial number 10470. I'll give it a shot here first on MF3D before going to Sell-3d. If it doesn't sell here or there, then it's off to eBay. 30 days to return.
The camera is in excellent cosmetic and working condition. I just got it back from having it cleaned and lubed. The lenses are very clean and all speed settings from fastest to slowest, though not exact, operate smoothly and consistently. I have a shutter speed tester and these are the results from the tests that I ran.
Setting / Duration in Seconds / Result in Seconds
------- ------------------- --------
1 1.000 0.71
2 .500 .45
5 .200 .20
10 .100 .090
25 .040 .045
50 .020 .028
100 .010 .012
300 .003 .005
The rollfilm back operates very smoothly and the numbers are spaced in a way that maximizes the size of each stereo pair. As a result, the image sizes are approximately 63mm wide, and with the appropriate aperture and hyperfocal settings are sharp from edge to edge.
I filmed the camera going through each of the speed settings and firing them multiple times in order to demonstrate how cleanly and consistently the shutter operates. Please see the youtube link for photos and a video of the camera going through each of the shutter speeds. It's probably the nicest camera that I've ever owned.
