Olympus OM system close-up and macro equipment

Close-up lenses


Olympus included 2 single-element close-up lenses in the range of accessories for the OM cameras, one for lenses with a 49 mm filter thread and the other for lenses with a 55 mm filter thread. Both lenses were the same strength, +2.5 diopters.

In addition to these general-purpose close-up lenses, Olympus also made the Close-up Lens 80mm MACRO f=170 mm which is intended for use only with the Zuiko Auto-1:1 Macro 80mm f/4 lens.


Only one version of each lens is known.

CLOSE-UP LENSES 49mm f=40cm, 55mm f=40cm

These two close-up lenses provide the most economical method of taking close-ups with the OM-1 standard lenses. The 55mm close-up lens is used with the standard 55mm F1.2 and the 49mm close-up lens with both the standard 50mm F1.4 and 50mm F1.8. With these close-up lenses, the minimum focusing distance of the standard lenses can be continuously varied from 45cm (17¾″) to 19cm (7¼″). At the minimum distance, a 12 × 8cm (4¾″ × 3 1/8″) area can be photographed full in the frame.

The 49mm close-up lens can also be used with the ZUIKO Macro 50mm.

How to Use Close-up Lenses

  1. These close-up lenses thread directly on the standard lenses without affecting the automatic diaphragm mechanism.
  2. Since depth of field is extremely shallow in close-up photography, the lens aperture should be stopped down between F8 and F11 to obtain maximum sharpness.
  3. Make it a rule to use a focusing stage, tripod and cable shutter release to eliminate vibrations that could degrade the image quality.
  4. For the best picture quality, light the subject area as evenly as possible.

After Olympus shifted their emphasis away from the OM series, they introduced better-quality, achromatic close-up lenses for their fixed-lens iS-series SLRs. These close-up lenses were available in both 49mm and 55mm sizes. They were supplied with a plastic diffuser that clips onto a groove around the lens to soften the camera’s built-in flash and stop the front of the lens from partly blocking the flash.

These iS series close-up lenses can be used on OM lenses with 49 mm and 55 mm filter threads, and produce significantly better results than the close-up lenses designated for the OM series.
