The '''Panorascope''' is a panoramic stereo camera for 16 mm cine film, made by the Parisian company [[Simda]] from about 1955. It can use film with either one or both edges perforated; with double-perforated film, the image is 10x20 mm, and with single-perforated,  11x20 mm.

The Panorascope is a panoramic stereo camera for 16 mm cine film, made by the Parisian company Simda from about 1955. It can use film with either one or both edges perforated; with double-perforated film, the image is 10x20 mm, and with single-perforated, 11x20 mm. A standard roll of film allows 120 stereo pairs, or 240 normal (mono) pictures.[1]

The camera body rather resembles an amateur cine camera, but is held flat for use. Sylvain Halgand's Collection d'Appareils describes two models of it. The first has a pair of fixed-focus 25 mm f/3.5 Roussel Microcolor lenses, and a shutter with speeds 1 - 1/250 second, plus 'B';[2][3][4] this is synchronised according to McKeown,[5] (and the PC socket is visible in the second-type Panorascope at Welt der Stereoskopie).[6] It has a reflex viewfinder (a large brilliant finder), using a viewing lens mounted between the taking lenses, and a folding frame finder which erects over the reflex one, on top of the camera. Also on the top is a large advance knob, a frame finder and an accessory shoe. The camera can be set to take single (mono) or stereo pictures.

The second model of the Panorascope is broadly similar.[6][7] It also has fixed-focus 25 mm f/3.5 lenses, which are now by Angenieux, and the same shutter. Instead of the frame finder it has a folding reverse-Galilean finder, with the eyepiece at the back of the camera (probably considerably more convenient to use than the original frame finder). Whereas the first model is finished in black leather, the second has two-tone grey covering.


Notes

  1. ↑ This number of frames is stated in an advertisement for the Panorascope, 1956 at Sylvain Halgand's Collection d'Appareils, though the auction listings at Westlicht (cited below) say the camera takes 300 pictures per roll of film. Perhaps the frame counter counts to 300.
  2. ↑ Panorascope (extensive notes, with pictures of the first model (an unusual example without any engraving on the lenses), at Collection d'Appareils.
  3. ↑ Panorascope (first model), shown with a Simda stereo viewer and a mounting card for four stereo pairs, sold at the December 2009 Westlicht Photographica Auction in Vienna.
  4. ↑ Panorascope (first model), showing the removable film chamber cover and film spool; sold at the November 2007 Westlicht auction.
  5. ↑ McKeown, James M. and Joan C. McKeown's Price Guide to Antique and Classic Cameras, 12th Edition, 2005-2006. USA, Centennial Photo Service, 2004. ISBN 0-931838-40-1 (hardcover). ISBN 0-931838-41-X (softcover). p894.
  6. ↑ 6.0 6.1 Panorascope (second model) at Welt der Stereoskopie; several pictures of the camera, including the film chamber, a page from the user's manual, and the viewer with some mounted stereo pairs.
