Despite the caustic opinions expressed here about the S2, Leica claim that the number of pre-orders exceeds expectations.
Go and look at that file from that PDN article at full rez. Then, go and look at yourself in the mirror, and ask yourself, "if I didn't know that that file was from a Leica camera, would it blow me away?" You guys are suffering from Red Dot Hope-itis, and it's going to cost you a lot of money. It's a fine file, but it's just another digital file. It's not like it's some revolution, in the way that Velvia was, in the old days. It's just another digital file.
After you do that, go back to that same mirror, and say this sentence to yourself, three times without stopping: "Leica: Twenty-seven thousand; 5DMarkII: Twenty-seven hundred".
And if that doesn't work, then make up a sentence about the usable ASA's of the two cameras, and that should do the trick.
If you're still feeling shitty about yourself after all that, then go get a haircut, and maybe a pair of new shoes. There's no need to drop $35k to feel good about yourself. Or, go buy ten 5dMarkII's, and give nine of them away to young, hungry high school students, and feel good that you contributed to them expressing themselves.
