I am excited about the D7k. One, because it's "pro" enough to be a backup to the D3-series, but not as expensive and heavy as a D300 series. Two, because it's got 1080p video (lol, haha!)
Quick sanity check on SNR and micron sizes (JA, your input here invaluable):
D40 6mp - 7.9 micron CCD
D40x 10 mp- 6.1 micron CCD
D60 10 mp- 6.1 micron CCD
D80 10 mp- 6.1 micron CCD
D200 10 mp- 6.1 micron CCD
D300 12 mp- 5.5 micron CMOS
D3100 14mp- _._?? micron CMOS?
D7000 16mp-4.78 micron CMOS
D3/D700 12 mp - 8.5 micron CMOS (largest pixel size of ALL current DSLRs)
So, ummm, isn't Nikon going in the WRONG direction here with SNR. . .since larger micron size is better?
Or are we at the cross roads of Physics and Computer Engineering, where they basically can make shit look less noisy than it physically is?
