Bob,

I agree with Martin that if you need 400 speed than you are probably better off
using a film optimized for that speed. As far as 800, that is close enough to what
we all agree is the "true" ISO speed of D3200, namely 1000 or 1200, that you might
well get perfectly good negatives with a bit less developing.
