  • FOOTAGE COUNTER: adds and subtracts accurately in forward or reverse motion and automatically returns to zero when film is reloaded into the camera.

Notes and Comments

In 1965, the body of the single lens mount H-16 M was redesigned to include a 1:1 drive shaft. To make room for this shaft, the "I-T" time lever was replaced with a small knob that was located next to the speed dial. Although it was only the third version of the H-16 M, it was termed the M-4; the trailing number "4" was used to identify all H model camera bodies with the newly introduced 1:1 drive shaft.

Cameras in the H16 M Series:

H16 M, H16 M-3, H16 M-4 and H16 M-5.

Serial Numbers and Dates of Manufacture

The serial number on this model is inscribed on the flat base of the camera body. The H16 M-4 began production in 1965 and continued to be manufactured even after the introduction of the H16 M-5, as it accommodated users who felt a 100' film capacity was sufficient.
