Adding to their growing full-frame L-mount lens lineup, Panasonic Lumix is introducing the portraiture-friendly S 85mm f/1.8.

The new Lumix S 85mm f/1.8 is a relatively small, light, and affordable lens that gives photographers a short telephoto reach that’s perfect for portraits or any other scenario where good subject isolation is necessary. The combination of 85mm and a low f/1.8 aperture means that subjects can be further away while still achieving shallow depth of field for pleasing separation.

Inside, this 85mm features nine elements in eight groups, two of which are extra-low dispersion elements to control aberrations and increase clarity. There’s a linear autofocus motor for quiet and quick focusing and has a minimum focus distance of 2.62 feet (0.8 meters). The lens uses a dust, moisture, and freeze resistant construction for durability and weighs 12.5 ounces (355 grams). The front filter thread is 67mm and there’s nine rounded aperture blades for a more pleasing out of focus quality.

The Lumix S 85mm f/1.8 is priced at $597.99 and is available to preorder now. It is the first of four L-mount f/1.8 prime lenses in the Panasonic pipeline, with the 50mm f/1.8, 35mm f/1.8, and 24mm f/1.8 coming in the future.
