Does the Merrill go to F16, my Dp1 stopped at F11.

Hmmm . . the calculation was for a SD1M with the APS-C sensor, 4.9um pixel pitch. I don't know about the DP1, I'm just a humble housebrick owner, lol. Even the D50 has gone . . .

I did try f/11 in the calc, it said MTF of 0.16 (16%). Note these calculated MTF's are not sensor MTF's. A sensor might have an MTF of 0.55 at Nyquist, so the captured image would have 0.16 x 0.55 = an MTF of 9% - enough to show artifacts, reckon?

In other words, f/11 won't do what you want, unless it has bigger pixels?
