The Panasonic Leica DG Summilux 25mm f/1.4 lens is a normal lens for Micro Four Thirds system cameras. It is co-branded between Leica and Panasonic, built in Japan under Leica management.
Focusing is internal, so polarizing filters can be used consistently. The 46mm thread lets a Micro Four Thirds user share filters between it, the Panasonic 14mm, Panasonic Lumix 20mm, Panasonic Leica 45mm, Panasonic 45-175mm, Olympus M.Zuiko Digital ED 12mm f/2 and Olympus M.Zuiko Digital ED 60mm f/2.8 Macro lenses.
Reviews are positive,[1][2] ranging from "very sharp"[3] to "sensational".[4]
