Olympus's macro telephoto for the OM system — the 135mm f/4.5 Macro for specialised close-up work.
The Olympus Zuiko 135mm f/4.5 Macro is a dedicated telephoto macro lens for the OM mount system. At 135mm, it provides significantly more working distance than the common 50mm and 90mm macros — invaluable for photographing skittish insects and small subjects that would be disturbed by closer approach. The f/4.5 aperture is modest but adequate for macro work.
Optical performance at macro distances is excellent. The lens is optimised for close-range photography with flat-field correction for reproducing flat subjects. Sharpness at macro range is outstanding. The 135mm focal length provides comfortable working distance — approximately twice that of a 50mm macro — essential for insect and wildlife close-up photography.
Olympus OM mount, manual focus. Filter thread is 49mm — standard OM size. Weight is approximately 420 grams. Build quality is excellent with precision metal construction. The extended helicoid provides close focusing capability. Compatible with Olympus Auto Extension Tubes for even higher magnification ratios.
Uncommon on the used market — specialised macro lenses are less common than standard focal lengths. Check for smooth helicoid operation and clean optics. An excellent macro lens for OM system photographers who need more working distance than shorter macros provide. Adapts well to mirrorless for a 270mm equivalent macro on MFT.
