Will do.

I can tell you that the Tokina SD is noticeably smaller and lighter
than the SMC. About 20% shorter; 72mm filter instead of 77 or 78mm;
probably 25% or more lighter. I don't have the tripod mount for the
SD, though, so it might not make the October trip. It would be much
easier to handle than the SMC without its collar, though.
Plus the SD has the "A" setting for Tv shooting, which makes
motorsports photography a lot easier. For any spot on the track, I
generally want to force the shutter speed, so that the pictures end up
with a feeling of speed (wheels blurring a bit). The apertures for
that spot then move around maybe +/1 one stop as the lighting changes.

I'll remember that. Stopped down should be no problem, though. During
daylight, when I'll be using the 400, I'll have to stop down (about f/8
to about f/22) to keep the shutter speed between about 1/125 and 1/500.
Dusk and night, I'll be using shorter and faster lenses.
