The Leica DG Summilux 25mm f/1.4 is a standard prime lens for the Micro Four Thirds system, and will work on any Olympus or Panasonic Micro Four Thirds camera, it has a large f/1.4 aperture, which should give a narrow depth of field and background blur.
We took a number of photos of the lens on an Olympus PEN Lite E-PL3, but we've shown it here mounted to the Panasonic Lumix G3.
The lens has a minimum focus distance of 30cm, meaning it's not ideal for macro photos, but it should make an excellent portrait lens. Focusing was quick and the build quality is good.
The large grip surrounding the lens is used for manual focus, however, it is not a directly connected manual focus system, instead using a "drive by wire" electronic control.
The lens is made by Panasonic, to Leica standards and has two aspherical elements.

The Leica DG Summilux 25mm f/1.4 lens has the brightest / largest aperture available on a Micro Four Thirds lens available from Panasonic or Olympus, and as such with the Leica quality of manufacture commands a high price of around £489. There also appears to be some purple fringing particularly on the chrome highlights of the cafetiere in the photo above, although other photos, where the aperture has been stopped down, show excellent detail and sharpness. The Leica DG Summilux 25mm f/1.4 lens could also be of particular interest to video users. We expect to review this lens shortly.
