I just started the Leica M8 Magenta Madness Flickr group.
About Leica M8 Magenta Madness
The Leica M8 has a sensor that is overly sensitive to infrared. This problem causes a magenta hue on certain blacks, particularly fabrics. The color is also visible directly in lights and on anything that is lit by strong infrared light.
There is a promised firmware update and IR/UV filters are just now shipping to early M8 customers with more to follow for the rest of us real soon now.
Until we get our filters, why don't we call this a "feature" and share our Leica M8 Magenta love with each other?
