Closer Look at the OM-System 50mm Macro

 Here's a black and white image of the legacy Olympus OM-System 50mm f2 Auto-Macro on a modern micro four thirds camera -- the Olympus OM-D E-M1 Mark III.

Because this prime lens was designed for SLR cameras, it's big and heavy, although the Olympus OM-System was smaller than other SLRs.

The grip and the size of the E-M1 III make it work well on this camera. I would not want to use it on my smaller PEN-F without a grip attached.

This copy of the lens, which I acquired used on eBay, is in good shape, and looks great on the camera. The wide rubberized focus ring operates smoothly with its wide throw. For manual focus work, I prefer this approach to the focus-range switches used on later model macro and telephoto lenses.

The aperture ring with click stops is located at the front of the lens. A focus-distance scale is found at the back of the lens behind the focus ring. A Fotodiox Pro OM-MFT adapter attaches the lens to the micro four thirds camera.

This lens and virtually all of the other fantastic OM-System prime and zoom lenses are still available on the used market.
