>>107337 The leica does better B&W basically just because it acts like it's got a faint red filter on it at all times.
B&W film works by having a bajillion megapixel sensor, but with each pixel only storing one bit of information. Each grain is either exposed or unexposed. If it's had a certain threshold of light hit it, it's exposed. Otherwise, no. And most black and white films don't actually respond to all wavelengths of light (most are somewhat insensitive to red, I believe. The ones with 'pan' in their names are sensitive to everything. And they're a dying breed, if not already gone).
SO: While B&W can has crazy huge resolution, it *needs* that crazy huge resolution because it needs quite a few grains to represent any of the 255 values that a digital pixel can represent. Right now, film is winning because they can cram a lot more grains into a 24x36mm rectangle than they can pixels, so film can give you more range even with the dithering. But Moore's Law suggests that that won't be the case for much longer. It's already passed it for color, since these same facts hold for color (but times three, since it needs enough red, green, and blue grains rather than just enough black grains to equal a pixel)
