Panasonic LUMIX S 85mm f/1.8 (S-S85)
The LUMIX S 85mm f/1.8 is Panasonic's affordable L-mount portrait prime — 355g, a 67mm thread, and part of the matched 24/35/50/85 f/1.8 set, which makes filter and balance consistency a real perk. It's a well-judged value portrait lens. The lack of O.I.S. means handheld low-light favors IBIS bodies, and buyers wanting maximum subject isolation will want an f/1.4 instead.
