Subject: [Leica] Ted vs "lag time"

I have tended to carry a point and shoot as a backup camera. 
Ultimately, I bought an Olympus Stylus Epic because, when closed, all 
optical parts, even the flash window, are protected, so that I can 
carry it in a trouser pocket.  Prior to that, my backup was a Yashica 
T4, whose lag is very noticeable; I estimate it to be about 1/4 
second.  Still, one summer when I fell on my face at the bottom of a 
flight of stairs at Francisco Franco's chapel near Madrid (see, the 
fascist got a last lick at me) and damaged both a zoom lens and a 
Nikon EF, I was left for a fortnight with nothing but the Yashica. 
It was great discipline, being forced to zoom with my two feet.  The 
only real restriction was when I went to the zoo, where it made no 
sense to photograph anything smaller than an elephant.

Back to the topic of shutter lag, human reaction lag, and sports 
photography.  Ted really has a point.  For years, I would try to get 
pictures of show jumping with the horse positioned at the top of the 
jump, and always managed to get the horse on the way down.  But I 
also was an untalented rider.  Now, there are at least two schools of 
how you ride over a jump.  The older school had you getting your butt 
out of the saddle, with your weight distributed between your feet and 
your knees.  The newer school had you sitting normally on the saddle, 
but going forward as the horse leaps.  This gave you better control. 
The catch was that if you failed to anticipate the horses leap, you 
would go off balance backwards, and to prevent falling, you were 
likely to give the horse a painful jab in the mouth as you yanked on 
the reins, thus giving the horse wonderful negative training about 
jumping.  So, one very clever riding instructor had us counting 
backwards "3, 2, 1, 0," going forwards on "zero."  The idea was that 
we had to estimate from the get go how many strides the horse was 
from the jump.  And, of course, doing this out loud, if one missed, 
one's embarrassment was audible to the rest of the class.

The point to all this belabored story was that after I learned how to 
estimate how many strides the horse was from a jump, I used this 
technique on the ground to photograph jumping horses and it really 
worked.
