Hanimex — Auto Zoom Macro 75-150mm f/4.5 compact manual telephoto zoom in M42 fit
The 75-150mm f/4.5 was a shorter telephoto zoom in Hanimex's independent lens range, aimed at portrait and general use rather than the longer reach of the 75-300mm or 400mm options. It was made in Japan by a third-party subcontractor and sold under Hanimex's own Auto Zoom Macro branding.
This lens is documented as a manual-focus, auto-diaphragm design made in Japan and sold in M42 mount. Other period mounts are plausible but unconfirmed. Weight, filter thread, minimum focus, construction and blade count are not reliably documented and are omitted.
The short 75-150mm range and modest f/4.5 aperture made this a compact alternative to Hanimex's longer zooms, better suited to portrait work than distant subjects. Documentation is sparse compared with other Hanimex zooms, so character is inferred from the wider range: usable stopped down, softer wide open.
This is an uncommon find on the used market relative to other Hanimex zooms, with few listings, so patience is often needed when searching. Given its age, checking for fungus and haze, and confirming the auto-diaphragm and zoom rings move smoothly, are worthwhile before buying.
