Leica M10 Monochrom (Leica)I have a new lust object: the Leica M10 Monochrom, a digital rangefinder camera with a full-frame, 40-megapixel sensor that only shoots in black and white. There are distinct advantages to going without the usual colour filters, which absorb light and reduce sharpness. This would incidentally make a hell of an astrophotography camera (high-end astroimaging shoots monochrome through specialized filters: you could do that with this but not a digital SLR). Fortunately for me, like all good lust objects this one is unattainable: it costs US$8,300, plus expect to spend as much again on lenses, because Leica.
