The Pentax ElectroSpotmatic (ES) II was the most advanced camera of the Spotmatic family. It was launched by Asahi in 1973 as an improved version of the Pentax ES, sold in the US under the Honeywell brand. It was available in black and chrome finishes, as well as in a Motor Drive and Data II versions. It stayed in production until 1975 and approximately 158,000 were made. 
Among the differences between the ES and the ESII is noticeable the return of the self-timer, due to the change in battery housing (now under the lens housing) which made space for it. Several features are different from the earlier model:
- A delayed-action (self-timer) is added, which can be cancelled by returning the lever to its normal position.
- Although the AE (electronically timed) and manual (mechanical) shutter speed ranges are the same as in the ES, the full range of speeds (up to 8 seconds) can be displayed in the viewfinder (the ES gave electronically-timed exposures up to 8 seconds, but the scale in the VF only went to 1 second).
- The metering sensitivity is the same, but allows the film speed to be set up to 3200 ASA (cf 1600 in the ES).
- A locked position is added to the shutter release button.
- The battery is now specified as four S76E (SR44) silver oxide cells, in place of the single 4SR44/PX28A used in the ES. The battery compartment is also moved to the base. The battery check is unchanged (the meter needle should fall below the notch in the middle of the VF scale).
- A viewfinder blind is added. This is closed (for use with the camera away from the eye) by a setting on the shutter speed dial.
- Camera type: 35 mm SLR camera, with through-the-lens aperture priority AE

- Lens mount: 42mm thread (Pentax-mount)
- Standard lens: 50 mm f/1.4 or 55 mm f/1.8 SMC Takumar
