A bit off topic:
One aspect I have harped on about the Merrills in other posts is the use of MED and LOW RAW settings.
I believe I garner a bit more of the DP2 look from the DP2M if I use it in MED or even LOW.
You gain more pixels in DP2M MED over the DP2, but LOW on the DP2M has less pixels than a DP2.
Been down that road myself. Medium resolution, as you probably know, is not pure binning, unlike low res. This because Foveon's VPS technology can not bin odd numbers of pixels so, buried in there somewhere is the 'I' word that we
foveonistas hate to use (INTERPOLATION).
As a non-printing guy, I did find low res on the SD1M to be quite adequate for my viewing needs (1280x1024px monitor). However, there was so little difference between SD1M low res and SD14 high res quality on my monitor that wresting with SPP 5.5.3 just wasn't worth the money
At one time I used to shoot watches in low res on the SD9 but, in that case, images down-sampled from high res. with a good editor were usually superior. After all, 2x2 on-chip binning is a simple averaging process (bi-linear?), nothing fancy - unlike Lanczos for example.
