Hanimar — Hanimex-branded 135mm f/2.8 manual telephoto prime, sold across vintage SLR mounts
Hanimex, the photographic importer and distributor active across the UK, Europe and Australasia from the 1950s, sold own-brand lenses under the Hanimar name alongside its cameras and accessories. The 135mm f/2.8 was the higher-specification telephoto prime in that range, above the standard 135mm f/3.5.
Like other Hanimar optics it was contracted to a Japanese lens manufacturer and sold as a manual-focus, manual-aperture prime across common SLR mounts of the 1970s and early 1980s, letting Hanimex serve multiple camera brands from one design. Optical construction, weight and filter size are not confirmed from available sources.
The faster f/2.8 gives noticeably more subject separation than the f/3.5 version, with the softer wide-open rendering and modest contrast typical of independent telephoto primes of the period; stopping down to f/5.6-f/8 tightens results.
Hanimar lenses show up cheaply secondhand but quality varied between batches. Check the mount matches the intended camera, the aperture ring clicks evenly, and the glass is free of fungus common in decades-old telephotos.
