The Shutter-Beam's IR beam is IDEAL for fast moving subjects, because
of its fast reactions, and reliable triggering. For a bird landing I
would put the IR beam about 14 inches in front of the branch the bird
is going to land on. The picture will be taken with the bird 2 inches
off the branch with its wings fully extended and its feet stretching
toward the branch. HIGH IMPACT PICTURE.
The nice thing is that the equipment
delays do not vary, like human reactions. Now that I know my camera
has an 85mS delay it will always have that delay. That is, as long as
I don't change any of the camera setting. This is not to say that all
8008 cameras have an 85mS delay, your 8008 may have a 75 mS delay.
This is to say that my 8008 has an 85mS EVERY TIME with the same
camera setting set (meter ON, Auto focus OFF, auto F stop and shutter
The propagation delay is dependent
on the automatic settings on your camera. Auto exposure, power saving
meter off settings(sleep states), auto focus, mirror lockup and many
more features of your camera have an effect on the cameras shutter
propagation delay. In general terms the shorter the delay the better.
Your subject is going to be moving
and you don't want it to move too far. Events in nature don't change
much. For instance the bird landing on a branch takes a similar
approach almost every time. Kinda like when we drive to work every
day. Same stop lights, same speed down the street. So you can take a
picture and adjust the equipment to change for prefered results and
then take another shot. Once you get the set up dialed in, you will be
amazed how many shots will be exactly like you wanted.
