Rolleiflex Model K8 T3 Camera

Astronomy

Accession Number: 2019.ast.145 (DAA-0010)

Description:

This is a box-shaped Rolleiflex camera. On the front of the camera there are a pair of lenses, one on top of the other in a figure ‘8’ arrangement, with a friction-fit plastic lens cover. The lower lens is lightly smaller than the upper lens. On the top of the upper lens there are two openings which reveal a pair of numerical indicators, one labeled ‘f’, the other ‘t’. Various other small knobs and dials surround the lenses. On the base of the camera there is a rotating latch; this appears to losen the back of the camera. Also on the base there is a central screw hole for attachement to a tripod or stand.

On one side of the camera there is a circular dial with a large arm that can be raised away from the body of the camera to allow the arm to be used to wind the camera. The handle of the winding arm tucks into a hole in the camera when the arm is stowed. On the other side of the camera there is one large dial with several settings in one, from a small central dial to a focusing ring that when turn retracts or protrudes the whole lens assembly. On this side of the camera there are also two small dials with no markings.

On the rear of the camera there is a chart wiht information about various settings for the camera, indicating with images of various locations (e.g. skiing, interior scene) and numbers indicating settings.

On the top of the camera there is a door that flaps up to revealing a pair of horizontally mounted translucent glass sheets above the lenses. These have small transparent circles in the middle. A circular lens flaps up to sit above the glass sheets and allows close inspection of the transparent circles. These are the focusing screens.

Function:

This is a hand-held camera used to take images on photographic film.

Condition:

Very Good: This camera is in very good condition, with few signs of wear. The numbers around the rim of the focusing dial are worn away and there are some small other marks on elements of the camera subject to rubbing or scraping (protruding pieces and corners/edges).

Manufacturer: Franke & Heidecke, Germany

Date of Manufacture: July 1966 – August 1976

Provenance:

This object was likely moved from the David Dunlap Observatory in Richmond Hill in 2008, upon the sale of the observatory. It was stored at the Department of Astronomy and Astrophysics until 2017, when it was moved to a new storage location in McLennan Physical Laboratories.
