a quick search on the net:

. . . The first Spotmatic to be introduced by Pentax was in fact the Spotmatic SP, in 1964. It was one of the very earliest SLRs to include through-the-lens metering. The Spotmatic SL was also introduced then, which was exactly like the SP, but without the metering. The name Spotmatic was aimed at the original design of the camera, which was to use a spot metering system. But even though the design changed, the name remained due to the already produced marketing materials.

Like many manufacturers it was incorporated into the M42 lens mount system, for maximum compatibility.

Other Spotmatic cameras followed, especially in the 1970s. This includes the SPII, SPIIa, SP F and even auto exposure models the ES and ES II. The SP though, in a nine year production cycle established Pentax as a serious maker in the SLR market and won over many fans.. .
