As a medium telephoto focal length, 90mm is particularly useful as a portrait macro lens when used with a film camera. When used on a digital SLR camera with a smaller image sensor, the lens provides a focal length equivalent to that of 140mm, so it can be used conveniently as a telephoto macro lens.
As manual focus is a common part of fine macro photography, the rubber pattern on the focus control ring of the lens has been improved to ensure a better grip. In addition, finishing touches like the graphic display and imprinting provide better visibility and loan a highl-quality aesthetic presentation to the lens.
