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

Wide prime for Micro Four Thirds

The Opteka 28mm f/2.8 is a manual-focus prime lens built for Olympus Micro Four Thirds cameras. It uses a 6-element, 5-group optical design that includes one super-low dispersion element to control aberrations. A 9-blade diaphragm and HD anti-reflection coating help produce smooth backgrounds and strong contrast. The all-metal barrel and clickless aperture ring give precise tactile control.

Shooters who want full manual control

This lens suits photographers who prefer setting focus and aperture by hand for creative or video work. The 28mm focal length yields a 56mm equivalent field of view on Micro Four Thirds bodies, useful for street, travel and environmental portraits. Buyers who need autofocus or electronic aperture communication should look at alternatives that provide those functions.

Simple mount and shoot

Attaching the lens is a standard bayonet fit on any Micro Four Thirds body with no adapters required. The 49mm filter thread accepts common circular filters and the included vented hood shades the front element. Because focus and aperture are entirely manual, users must remember to set both rings before each shot; forgetting either is the most common cause of missed exposures.
