The Honeywell Pentax H1 is a 35mm single-lens reflex camera, sold in the United States under the Honeywell Pentax badge that distributor Honeywell applied to Asahi Pentax bodies during the late 1950s and 1960s. It was positioned as an entry-level film SLR within that import line.

Sales data for the H1 in the UK auction market is extremely thin: a single recorded hammer result of £200 from 2004 is the only reference point we have, and that wholesale, pre-commission figure is more than two decades old. As of 2026, anyone trying to gauge what a Honeywell Pentax H1 is worth today should treat that lone saleroom price as indicative only and look at comparable Asahi Pentax bodies of the same era for a more current sense of value.
