Did a test last night of the moon again VR on continuously, on only
on shutter release, and without. All without anti-mirror shock and
at ISO 200. Had 1 or two images where the VR caused a little
unsharpness from the continuous on state, but others were all
sharp. VR I'd leave on for handheld stuff, generally turn it off
for tripod use with cable release (unless you're on a boat or
moving vehicle) -- it's really not a big deal. You can get a little
shift in the framing when the VR is first activated while on a
tripod, but if you let it settle down, then frame, then squeeze the
shutter, it's not a problem (at least for me). Shooting the moon,
one will usually crop the frame anyway and mag up 200% in PS, so a
little frame shift if you squeeze the shutter before VR settles is
really not a big deal.
For me, it's a great all purpose lens for what I shoot. I also use
and AFS 17-35mm, 50mm f1.4, 60mm Micro to cover the rest of the
range of focal lengths, but I still use the 80-400VR the most often
to keep the frame filled with my subjects. All the lenses are great
in general and should be great on a D100 which I may get as a
backup from my D1x.
Hand grip on the D100 with long lens should help in D100 handling.
One wasn't available when I tested out the D100 at the camera shop.
Thanks Mark,
I bought the Sigma 50-500 mail order but hated the 'feel' of it.
Just too heavy and the zoom was way too hard to turn. I got to try
the 80-400 VR in a store...the VR part really impressed me. So
I'll be hitching up the MB-100 grip and going to our kids sporting
events with the 80-400VR (should be here tomorrow). I'm glad I can
at least use a monopod. And I hope the D100 catches some of the
action (yes, I have D1 envy here

) Thanks for all the
suggestions.

The key to catching the action is really not ripping off a lot of
frames fast, but knowing the lag time on your camera and
anticipating the action so you squeeze the trigger at the right
time in order to catch
1. the bat contacting the ball on baseball
2. the foot on the soccor ball as it is kicked
anticipating it right and understanding your camera, you can run a
burst that gets the action sequence just right as the player lines
up, hits, and follows through -- all without having to have the
speed of a D1h or 1D -- though those are really sweet cameras as
well.
The key to good photography is know your subject and know your
equipment really well. Practice practice practice....
Cheers
