Opteka 28mm f/2.8 Manual Focus Prime Lens Micro Four Thirds

Wide-angle prime for Micro Four Thirds

The Opteka 28mm f/2.8 is a fixed focal length lens built for the Micro Four Thirds mount. It provides a 50-degree diagonal angle of view, equivalent to a 56mm field of view on the format. Photographers who prefer full manual control over focus and aperture will find its mechanical design suited to deliberate shooting.

Upgrade from kit zoom limitations

This prime replaces variable-aperture kit zooms that restrict low-light work and depth-of-field control. The constant f/2.8 maximum aperture gathers more light at the wide end, while the 9-blade diaphragm produces smoother background rendition. The jump is worth it when you need consistent exposure across the frame and shallower focus separation than a slow zoom allows.

Simple mount-and-shoot installation

The lens attaches directly to any Micro Four Thirds body with no electronic coupling required. Focus and aperture are adjusted via dedicated rings on the all-metal barrel. The main issue is forgetting that focus must be set by eye or focus peaking, as there is no autofocus motor. The 49mm filter thread accepts standard accessories, and the included vented hood helps reduce flare.
