Hi Lee,

Small question/suggestion.  Are you firing the T32's in parallel or using a
slave (peanut type) module to fire the off-camera flash?  We took a high
speed shutter camcorder and looked at sync-trigger speeds and the delay
between source and slave firings was very noticable.  This isn't a problem
in most applications but will be with the fast moving wings.  A few
milliseconds will add to the blur.  I'd also assume you'll be using a dark
neutral density filter along with f16-f32 aperture to get the non-flash
exposure down to 1/4 second or greater to remove anything that's not hit
with the flashes and keep natural lighting from showing up the wing movement.

Yes, this lens + extention should work out great.


Enjoy the trip and call me if you have car problems in Delaware,
