That huge $11k price tag will buy you an equally huge f/0.95 opening for those low light shots that your $5k Nikon just wasn’t getting. A French magazine leaked shots of the new Leica Noctilux 50mm Lens (pictured above) which will enable you to take shots like this (apparently candle light only):
Whether you intend to take suggestive shots of bare-chested men in dark rooms with it is your business, either way this thing is awesome. $11k awesome? No, but only because I don’t have $11k. By the way, that M8 it’s stuck to will run you another $5k. Start saving! Alternatively, just get this (called "One of the finest DSLRs ever produced") and spend the left over $12,000 traveling around the world and actually taking shots with it instead of leaving it sitting in a drawer which is what most people who can afford Leicas seem to do.
