What are the alternatives to the om system m zuiko 90mm f 3 5 macro is pro?

I don't have a list of other lenses to put beside the OM System M.Zuiko 90mm f/3.5 Macro IS PRO, so I won't guess at alternatives. What I can tell you is what it does: it's a weather-sealed, stabilised macro lens for Micro Four Thirds that reaches 2x magnification, and on that sensor it frames like a 180mm on full frame. You can check its lens page for the full list of cameras it fits.

If you're comparing it with lenses from other systems, the focal length converter will put them on the same footing. The sensor sizes page explains why a Micro Four Thirds lens looks so different from its full-frame equivalent.
