| Kodak Motormatic 35 |
by John Hufnagel
The Kodak Automatic and Motormatic series were Kodak’s last American made 35mm cameras, and their first automatic exposure 35mm cameras. Tracing their original roots back to the Kodak 35 of 1938, there were seven different models; the first, the Kodak Automatic 35, was introduced in 1959 while the last, the Motormatic 35R4, was introduced in 1965. Production ceased in 1969.

Based largely on the Kodak Signet 50, the Kodak Automatic utilized that camera’s basic body, film transport, and lens. The lens was a 44mm f/2.8 Kodak Ektanar (Lumenized), a 4-element Tessar design with front element focusing. Like many of Kodak's better lenses of this period, the lenses are somewhat radioactive. The camera had a drum take up spool and bottom mounted advance lever.

The main difference between the successive models of each camera were in the flash capabilities, evolving from the side mounted M2 flashbulb gun of the original models, adding an aperture/distance guide number (GN) interlock on the B model), through the integral top mounted AG-1 socket and reflector of the F models, and finally to the top mounted Flashcube socket on the R4 models. Only the original models had manual exposure settings, Kodak evidently feeling that manual exposure control was only necessary for flash operations. On the B, F, and R4 models, it was not possible to manually set the aperture.
These are fixed-lens viewfinder cameras; focusing is by scale or estimate. The bodies are made from bakelite, with metal inserts, fittings, and attached plates. The top plate contains (from the right) the brightline window, the centrally located viewfinder, and the selenium meter cell. In addition to the viewfinder having a brightline for the 44mm lens and parallax marks for 3 and 5 feet, it displays the words “Close-ups”, “Groups”, and Scenes” when the focusing ring is set to the appropriate click stop.
The selenium exposure meter was calibrated for ASA speed via a dial on the left top plate. With the introduction of these cameras, Kodak finally abandoned the EV system, the meter now reading out in f/stops. Both cameras utilized the trap needle exposure automation system first developed in the Kodak Super Six-20 of 1938. Slight pressure on the shutter release set the 4-bladed aperture diaphragm at the f/stop indicated by the meter needle. The meter readout was located on a flat panel directly on top of the lens mount. On the original models, the same panel featured a movable pointer used to select f/stops when the camera was in manual exposure mode. The selenium photocell required no batteries, however the F and R4 models had a battery compartment to power the built in flash units.
The Automatic 35 originally sold in 1959 for a list price of $84.50 USD (app. $600 USD in 2007). The Motormatic 35 originally sold in 1960 for a list price of $109.50 USD (app. $765 USD in 2007).
