I think a 28mm lens is too wide for an Iridium Flare. A 50mm lens is the best for
a 30-40 second pass (so you can take a picture of the sat from the moment it rise
magnitudes to the end). If you want to register only the brightest moments you can
use a 135mm lens.

If you want to see my photographs go to:

and click on "Fotografie di Iriudim Flares". All images were taken with a 50mm
lens and 800 ISO film.
