This got me curious, so I set up a little test. Using a bellows at maximum
extension, 80mm macro lens and two T-32's, I focused on a 18 0rey card. I
positioned the flashes at 45 degree angles to the card thirty cm (twelve
inches) away, set to full control by the OM. Then, stop by stop from f/4 to
f/22, I made an exposure and watched the ready light. In both cases, OM-2n
and OM-4T, the ready light blinked, indicating correct exposure. The only
observed difference is the strength of the ready light's response. In the
OM-4T, the light blinked quickly, the OM-2n blinked much more slowly, and
fewer times, from f/11 thru f/22. The images are identical from both
cameras. At least for my two, there is no significant difference. Other's
mileage may vary.
