Some Micro Four Thirds enthusiasts have been praying for a lens like this, and Panasonic has delivered. The Leica DG Summilux 25mm / F1.4 ASPH is to Micro Four Thirds what the fabled “fast 50” was in 35mm film photography’s heyday.
All the major brands that made SLR film cameras had at least one 50 mm lens with a maximum aperture of f/1.8 or f/1.4 or sometimes f/1.2. The 50mm was the so-called normal focal length but for Micro Four Thirds “normal” translates into a 25mm focal length.
The Leica DG Summilux 25mm lens is constructed of nine elements in seven groups including two aspherical lenses and one UHR (Ultra High Refractive) index lens. It also benefits from Panasonic’s Nano Surface Coating, which helps reduce ghosting and flare.
Panasonic says the lens will be available in August. The company hasn’t announced pricing although one US online store has a pre-order price of around $600.
