Olympus America Inc. V311040BU000 75mm f/1.8 Micro Four Thirds camera lens

Portrait lens for Micro Four Thirds

The Olympus 75 mm f/1.8 prime lens fits Micro Four Thirds cameras and delivers a 35 mm equivalent focal length of 150 mm. Its bright f/1.8 maximum aperture and nine-blade circular diaphragm produce smooth background blur suited to studio portraits, stage work and indoor sports. The metal-barrel construction weighs 10.7 oz and uses 58 mm filters.

Upgrade from slower zooms or shorter primes

Photographers moving from variable-aperture zooms or narrower primes gain two stops of light at f/1.8 and a longer working distance for head-and-shoulders framing. The jump is worth it when shallow depth of field and quiet MSC autofocus matter more than zoom flexibility, especially in low-light venues where f/22 minimum aperture still allows stopped-down control.

Micro Four Thirds mount limits sensor coverage

The lens projects an image circle designed for the Micro Four Thirds format, so it cannot cover larger sensors such as full-frame or APS-C without vignetting. Angle of view is fixed at 16 degrees, and close focus stops at 2.76 ft (29.5 in) with 0.1× magnification, ruling out true macro work. Autofocus speed depends on the camera body’s imager drive.
