For most shots you won't get the max out of the potential achievable with a
35mm system, in my experience 6MP is very comparable over 90% of the case.
My experience told me RVP is noticeable better than 6MP DC and RDP III is
already very marginal, I'm talking about resolution only actually the tonal
quality of 10D is much better than both. Film is the biggest limitation
here, everyone has experience in good quality SLR DC know the difference,
you won't see any grain at low ISO. Extra pixel doesn't mean anything if
they contain no extra information.
You have mentioned 210MB file with 5400dpi, it must be at 16 bit, a easy
math.

No, actually, I'm ahead of them. A lot of the shots are of F-15s, F-16s,
and Tornadoes blasting off in full burner, made from between the runways at
Nellis during a Red Flag launch. An F-15 is a big airplane, but it fills
about half the linear dimension of the frame when shot with a 400 from where
I was. The Canon digital shooters were mostly using the 100-400/4.5-5.6L IS
and 10Ds. They are ahead of me by the magnification factor of 1.6 for that
camera, acheiving almost full frame shots. But, I start out with a 39 Mpx
full frame scan, crop to their framing, and now I'm ahead by about 9.75 Mpx
to their 6.3.

am even more in love with it after seeing these scans. I sure was working
to focus, though. Jets are fast.

it. I had been forgetting to convert to 8-bit before saving the final 50 Mb
submission files.
