the easiest thing to do would be to layout a detector exactly like the S3/S5 sensor only put more of them in, that is a full frame sensor,and let Nikon make it and also let Nikon use it.
Now that's an interesting thought. Opens up all sorts of lovely concepts...
It would drop into a D700 body which would give us a 14 mp very high dynamic range and relatively slow camera.
Actually, 13.5mp. 6*1.5^2. 13.5mp each of S and R pixels...
Slow because without significant redesign, which it appears Fuji is not willing to do now, it would take a long time to get all that information off of the chip.
The design is not "significant". Simply a matter of bringing 1/8 the rows out on 8 separate lines (even 1/4 the rows out onto four separate lines would be a big help). The big problem with S5 was that Fuji wasn't willing to do even "trivial" redesign on the sensor, they used the same single channel design. A D200 body could quite happily read four channels at 12.5MHz, but with a 1 channel sensor, you've got 12 S + R pixels to deal with, so 1 frame/second. Had Fuji done a
very easy bit of layout, it would have been a 4 frame/second body.
A D700 body can do 96million pixels/second on 8 channels at 12MHz. It would happily shoot a Fuji 13.5mp SR at 3.6 frames/sec in HDR mode, 7 fps in normal mode.
So far no other chip even comes close for DR into the highlights, like the S3 or S5 in RAW and it would be so great to have that in a D700 body.
I would love it.
1 FPS would be fine with me.
Oh yes and the files would be about 100 MB
54 megs if uncompressed and using 16 bits for each pixel (the "Fuji lie"). But you gave the clue yourself, earlier. "let Nikon make it and also let Nikon use it." If Nikon actually uses it, they're not going to have the slightest interest in propagating the Fuji lie. So, 12 or 14 bits per pixel, and lossless raw compression. 25 meg raw files...
640 shots on a 16 gig CF. Get you through a wedding without having to endanger data by swapping cards in the field. Hopefully, a new "s" body like D300s, with double redundant card slots.
