Barry, you have posed a very real problem for outdoor night sports
photography. 30 feet at f/8 requires a GN240 (feet); at 50 feet a GN400
(feet). [Note: conversion to meters is divide a feet GN by roughly 3.25 -
3.3] Hmmmm. That's not counting the presence of ambient lighting, though.
A pair of T-32's (one BG2 and the other shoe, or a T-45) and ISO400 film
could allow you to stop down that far and recommend an experiment with that
(before a critical game) and some ISO200 if it looks like the ISO400 gives
you enough reserve. The level of ambient light in the stadium will make a
difference.
ISO200 looks to be at the very edge of capability and requires longer
recovery time. The BG2 could handle one of the fairly fast, but unless you
have a remote battery pack on the shoe mounted T-32 it will be operating on
its four AA's and you'll be waiting for it. The desire to stop down for
DOF is sound. With a 150mm lens you will have enough DOF to cover 30 - 50
feet. Also at f/8 a focus distance of about 40 feet at that focal length
would still cover that range with the DOF (50 feet would be close to
hyper-focal). IMO I don't think you have much of a chance at ISO 50/100,
or stopped down beyond f/8.
There was an interesting article in the most recent Photo Techniques about
a NY boxing photog during the 1950's who used a 4x5 with telephoto. They
don't dare allow the type of lighting he used today. Because of the boxing
ring size, they used to surround it with remote _flashbulbs_. Now there
was a challenge to get the Decisive Moment! The setup and recovery time
for the next shot gave you only a few chances to get something good during
an entire match. His nickname was "One-shot Charlie" in recognition of his
real skill.
