By your standards this is very unscientific and shallow I guess.

Ming says: "The 20/1.7 has the highest overall scene contrast, but the 17/1.8 wins out in microcontrast and reproduction of fine detail structures – personally, I prefer this as it gives me more latitude for processing before the shadows and highlights block up."

My comment: It's clearly evident from Ming's samples that the 20 does better with respect to global contrast and microcontrast (the contrast between smaller details) alike. When Ming says that he has "more latitude for processing [with the 17] before the shadows and highlights block up" he means that he can apply more sharpening. But the point here is that the 20 simply needs less sharpening by virtue of having more microcontrast in the first place. And not having to sharpen (much) is preferable on all counts. It doesn't increase the noise level and yields a cleaner, more natural look.

Ming's conclusion about microcontrast seems bizarre to me, in light of his 100% comparison crops. The superiority of the 20mm f/1.7 in terms of sharpness and microcontrast is plain as the light of day (to me) in his samples. It's hard to understand how he could look at the same comparison photos and reach the conclusion he did.
