Panasonic Lumix S 85mm f/1.8 L-Mount camera lens

Portrait prime for L-Mount

The Panasonic Lumix S 85mm f/1.8 is a medium-telephoto prime lens built for L-Mount full-frame mirrorless cameras. Its wide f/1.8 aperture creates shallow depth of field and smooth bokeh suited to portrait work. The optical design uses nine elements in eight groups, including two ED lenses to control chromatic aberration. It is a compact, lightweight option for photographers who want a fast portrait focal length.

Mount and coverage check

Verify that your camera body uses the L-Mount bayonet and has a full-frame sensor to match the lens image circle. This is a fixed focal length lens, so it does not zoom; ensure 85mm suits your typical working distance. The lens accepts front filters, so confirm the thread size before purchasing filters or a hood. Autofocus and aperture control require a compatible L-Mount camera body.

Sealed build for field use

A dust, splash and freeze-resistant construction protects the barrel during outdoor shoots in adverse weather. The focus mechanism suppresses breathing, helping maintain consistent framing while pulling focus during video recording. The wide f/1.8 aperture allows lower ISO settings in dim light, reducing the need for high sensor gain. No stabilisation motor is mentioned, so steady handheld results depend on body stabilisation or technique.
