I'm saying that the lateral motion necessary for stereo will work
against sharpness, but there's not a lot you can do about it. If you
have a good crisp day with lots of lift and little wind, your pilot will
be able to adjust his speed and course without much impact on camera
movement. If you have poor lift conditions and the wind is working
against you, your going to get more vibration and drift. Luck plays a
big part in this for lighting, shooting conditions, etc, so start living
right... 8-)

With regard to digital, we'd have to know what the final output is going
to be and if a high res MF scanner is available to you. But in any
event, I don't think you'll be renting a Hassy with an f/2 Xenotar for
$35/day, means you'll shooting at a 1/60th at f/2.8...

Again, depending upon your final output, I'd think about pushing the
film an extra stop or two...
