Daniel Cox posted his short test with the new 12mm f/1.4 Leica lens on Naturalexposures (full size sample on Dpreview):
“I love the amazing details that are easily seen from the center of the lens all the way to the extreme corners, even when shot wide open. It’s build feels as robust as any lens I’ve ever handled. As much as I love this new wide angle option we’ve been given, it really is a specialty lens for most photographers. The Lumix Vario 12-35mm F/2.8 also covers the 24mm range. Having a zoom can be a big advantage, especially one as sharp as the 12-35mm Vario. But if you want to shoot the Milky Way or any other scenes after the sun has gone down, this is by far the best lens we have for Micro Four Thirds users.”
