Pentax ES II Motor Drive

The Pentax ES II Motor Drive, introduced in 1973, was a significant evolution in Pentax's popular ES series of 35mm SLR cameras. Building upon the original ES model, it featured Pentax's proprietary shutter-priority autoexposure system, allowing photographers to set the desired shutter speed while the camera automatically selected the appropriate aperture based on TTL (through-the-lens) metering. This was a crucial innovation for amateur photographers seeking easier exposure control without needing to master manual techniques. The inclusion of the optional motor drive attachment enabled continuous shooting at up to 2 frames per second, making it practical for sports, action, or documentary work where capturing fleeting moments was essential. The camera maintained Pentax's reputation for solid, user-friendly construction within a relatively compact and lightweight body for its era.

While not a revolutionary landmark like the Nikon F, the ES II Motor Drive represents a mature and practical application of early automation in consumer SLRs. Its shutter-priority system offered a good balance between control and convenience, complementing the existing manual and aperture-priority modes. The motor drive option significantly enhanced its versatility, appealing to enthusiasts and professionals needing faster capture rates. The ES II's reliability and logical control layout contributed to its success, cementing Pentax's position in the competitive mid-range SLR market of the early 1970s as a bridge between purely manual cameras and the increasingly automated models that would follow.
