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.

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.
