Do you think the image of SD14(SD15/DP1/2) is cleaner than that of SD1m(DP1m/2m) ?

In practice, increasing the number of pixels increase IQ. Until you hit that limit for fast degradation.

According to Clark, as we've discussed before, "that limit" is a pixel pitch of about 6um. The SD1 sensor, at 4.9um, is already beyond the limit according to Clark's criterion.

After reading Clark's article again, "that limit" is stated quite clearly as 5um which makes the SD1, at 4.9um, almost perfect in that regard, especially around the f/4 mark. Cameras with larger pixels at that same aperture would show "jaggies" more clearly on edges.

Note 1) to self from RAF days: "Don't assume - Check!"

Note 2) to self: must stop using the word "clear" in this thread . . .
