Olympus Pen F is a single-lens reflex camera featuring lightness of weight, maximum flexibility and ease of operation. It is equipped with a rotary metal focal-plane shutter with single-pivot, non-revolving shutter dial, synchronized for electronic flash use. The speeds range from B (bulb) to 1/500 of a second, ensuring that you can capture both fast-moving subjects and low-light scenes. The camera's Porroprism system finder offers 0.8x magnification and a 5x magnifier, providing a bright and clear view of the scene you're capturing. Additionally, the film advance lever is double-action, which advances the film, advances the film counter, presets the shutter, swings the mirror into position, and releases the automatic aperture system.
