Asahi Pentax Pentax MX
The Pentax MX is a compact, fully mechanical 35mm SLR introduced by Asahi Optical in 1976, using the Pentax K bayonet mount. It was positioned as the manual-exposure, match-needle counterpart to the aperture-priority ME, aimed at photographers who wanted a small all-mechanical body.
Auction data for the Pentax MX is sparse: a single 2023 UK saleroom result hammered at £44, so any sense of current value in 2026 rests on that lone data point rather than a stable range. Because this is a hammer price from a UK auction, it reflects wholesale conditions rather than retail asking prices, and what a clean, working MX is worth today can vary considerably with cosmetic condition and whether the meter is functional.

Sales History
Prices shown are realised prices — auction results and completed eBay sales, never asking prices. Most saleroom figures are hammer prices, before commission; some houses publish a premium-inclusive figure, and we do not adjust for condition. Dealer and retail asking prices are typically higher.

Frequently asked questions
What is a Pentax MX worth today?
On the limited UK auction evidence available, a Pentax MX sells for around £44 at hammer, though that figure comes from a single 2023 sale and clean, fully working examples may achieve more.
How much does a Pentax MX sell for at UK auction?
The only verified hammer price in our records is £44 from August 2023; with so little data, the realistic price for any given example depends heavily on condition, meter accuracy, and whether a lens is included.
Is the Pentax MX a fully mechanical camera?
Yes — the MX is a mechanical-shutter 35mm SLR, so the shutter operates without battery power and the battery is used only for the light meter.
