Pentax's screw-mount SLR — the H2, the S2 sold as Honeywell in the US, screw mount, 1959.
The Pentax H2 of 1959 was the name under which the S2 was sold in the United States through Honeywell, the firm that distributed Pentax there for many years. Mechanically it is the S2, carrying the H prefix for that market. It belongs to the all-mechanical screw-mount Pentax line that preceded the Spotmatic.
This is a 35mm film SLR using the screw lens mount that became the M42 standard, taking Asahi's screw-thread lenses. It has a horizontal cloth focal-plane shutter and a fixed eye-level pentaprism with an instant-return mirror and a wind-on lever. There is no built-in meter, so exposure is set by hand, and the body is fully mechanical, firing without a battery. It used automatic-diaphragm lenses that stopped down at the moment of exposure.
The H2 suits collectors, students and photographers who want a simple, sturdy screw-mount Pentax with a clear eye-level finder. It handles just like the S2, needing a separate meter or experience for exposure. It is a reliable, uncomplicated body for slow, considered work, and the Honeywell branding is of interest to collectors.
As a late-1950s body, condition is the main concern. Check the cloth shutter for pinholes and even travel, testing the slow speeds for stickiness. There is no meter or battery here. Inspect the pentaprism and finder for desilvering, haze or fungus. Test the advance and rewind for smooth movement. Clean, working screw-mount lenses determine how practical the camera is today.
