A 20 Mpix Foveon is not enough for 24x36mm.

76 lp/mm at the sensor would be good enough for any lens except an Otus mebbe.

Huh? If that was the case, then we wouldn't see any more detail in our photos when we step up from the SD9, SD10, SD14, or SD15 to the SD1 Merrill, but as you know Ted, even when using a zoom lens, like the 17-50mm f2.8 EX OS there is a significant amount of extra detail in those Merrill images.

. . . or were you just joking?

The Merrill's max resolution is 100LPM which can easily be reached using Sigma's best glass, in my case the 50 f1.4 A, 70 A macro and 85 f1.4 A all shot at f5.6. The key is the accuracy of the AF calibration (which admittedly can take some time--and patience).
