Pentax's compact M-series zoom — the 40-80mm f/2.8-4 Macro with fast start.

The SMC Pentax-M 40-80mm f/2.8-4 Macro is a distinctive zoom from Pentax's compact M series, pairing a wide-to-telephoto zoom with a macro switch for close-focus capability. Part of the same ultra-compact design philosophy as the 40mm pancake, the M zoom series prioritised small size without sacrificing optical quality.

40–80mm zoom range, f/2.8-4 variable maximum aperture (f/2.8 at 40mm), macro close-focus mode, SMC (Super Multi Coated), Pentax K bayonet mount.

The M 40-80mm Macro is highly valued for its combination of the fast f/2.8 wide end, a useful 2:1 zoom ratio, compact size, and built-in macro capability — an unusually versatile package for its era. The macro mode allows 1:2 to 1:3 reproduction ratios. This lens remains sought-after for Pentax K-mount shooters wanting compact versatility.

Test the zoom, macro switching, and focus helicoid operations. Confirm the macro mode engages cleanly. Inspect elements for fungus and haze. Confirm K-mount engagement. Check aperture blades for oil contamination.

Avg £40, steady over 2 weeks
