Wide 28mm prime for Micro Four Thirds

The Opteka OPTM2828M43P is a manual-focus 28mm f/2.8 prime lens built for Micro Four Thirds cameras. It suits photographers who prefer full mechanical control over aperture and focus for street, travel or candid work.

Aperture range f/2.8 to f/22 with 9-blade diaphragm

The nine-blade iris stays rounded from f/2.8 through f/22, giving smooth background separation at wide apertures and deep depth of field when stopped down. Six elements in five groups, including one super-low dispersion piece, keep chromatic aberration low across the range.

All-metal barrel with clickless aperture ring

A full metal construction and 49mm filter thread make the lens feel solid in hand while accepting common screw-in filters. The clickless aperture ring allows silent, stepless exposure changes — useful for video — and the compact 2 x 1.5 x 2 inch profile adds little bulk to a mirrorless kit.

Questions about this item

Will this 28mm Micro Four Thirds lens cover the sensor on my older Panasonic G-series body?

The 28mm focal length gives a 56mm equivalent field of view on Micro Four Thirds, and the Micro Four Thirds mount fits all Panasonic G-series bodies.

How can I verify the 9-blade aperture is stopping down smoothly after I mount the lens?

Set the clickless aperture ring to f/22, press the depth-of-field preview button on the camera, and watch the iris close to a small, round opening.

Does the box include a 49mm filter or hood, or do I need to buy them separately?

The package contains the lens, front and rear caps, and a pouch; 49mm filters and a hood are sold separately.
