Less difference now makes it easier to contemplate. More like $200-250 now.

That's roughly the same ratio, 100/64 = 156. I know that ratio holds for
the usable higher speeds on the A1. Do you know if it holds true for

I ran Fred Miranda's grain reduction on the A2 samples on Steve's
Digicams. It helped, but wasn't fully satisfactory. I suppose I need
something specifically aimed at digital noise.
