red eye and zoom lens

[neuroanatomist]

The zoom has nothing to do with it, really. Red eye is caused by having the flash pointing straight at the subject and too close to the optical axis of the lens.

I find that a flash bracket helps in those situations - I use an OC-E3 for triggering, as PWs can be unpredictable at very close range.

Wouldn't the subject and the optical axis be on nearly the same axis with an extended zoom though?

Anyway, good advice on the bracket.

It was a horribly lit room. Some can lighting above. I had the ISO cranked up as far as I could tolerate it (1600), but it still was insufficient.

I use a flash bracket with speedlight quite a bit. I get more red-eye when using a long lens. The flash bracket helps to angle the flash high enough above the lens that I do not get red-eye. Since I am farther away with the long lens the angle is smaller allowing the lens to see the red-eye reflection. It also is certain people. I have had it happen at a wedding reception and I find it is the same person every time.
