Nice pics under tricky circumstances.
I have the zoom extender, but have never tested it on manual. According
to the instructions, when set for 135mm, it raises the asa 100 GN from
32 to 42. So the stop would change from 2.8 to 3.7. That's over 3/4 of a
stop, but just shy of a full stop mathematically. For practical purposes
where you don't know the exact distance, it's one stop faster. So you
could close down a stop, move up one shutter speed, or move out further
with the 135/2.8.
This doesn't help use the 200/4 for longer distances, as the zoom
extender doesn't adjust past 135mm, so the GN stays the same for any
lens longer than 135mm. You could use the 200mm wide open at the same
distance for greater magnification, but would still need faster film or
lens or higher output flash to get more distance.

Most of the long shots were done w/ the 135/2.8 at about 50 feet at full
aperture. I wish I could have used the 200/4 for some, but I would need
to get faster film, or a more powerful flash. Has anyone used the zoom
extender for the T32? Does it give you much more power in the long
shots? <snip>
