Pentax Spotmatic F Motor Drive

The Pentax Spotmatic F (SPF) added full-aperture metering to all of the features found in the Spotmatic II. Full aperture metering required the newer Super-Multi-Coated (S-M-C) Takumar lenses with an aperture-position linkage to the camera. The camera retained backwards compatiblily with all earlier Takumar lenses.

There were a number of 'Motor Drive' editions produced by Pentax beginning in 1969 with the original Spotmatic and ending with the ES II in 1975.

The SPF Motor Drive System was offered in 2 different packages. The 'Set 36' consisted of the Spotmatic F camera which had been modified to accept the motor drive system, a SMC Takumar 50/1.4, the motor drive unit, the battery grip and a battery loader for AA batteries. The 'Set 250' consisted of the Set 36, plus a bulk film magazine capable of accepting 250 exposure bulk film.
