Ah. Glad this feature has been altered with the Elan 7. Red-eye
reduction is less useful with second-curtain sync because of the
delay with long shutter speeds, but it's still annoying to have the
feature disabled outright on the Elan.
As for second-curtain sync, as noted, there is the problem of the
E-TTL preflash. But I think the main reason why EOS cameras don't
ship with second-curtain sync enabled as a default (you have to
enable the mode deliberately with a custom function) is the fact that
with slow shutter speeds your picture essentially doesn't get taken
right away. You press the shutter release, the shutter opens, there's
a pause and *then* the flash goes off just before the shutter closes,
recording the foreground scene. So if you're trying to capture
someone's expression you may totally miss it.
