Ha no problem man,
I'll just steal a link from google:

Yup, the lens starts at 120mm, so she wont get anything below that.
See if this helps (pretend A-H is a physical distance, say 100 feet across):
A...B...C...D...E...F...G...H
With a lens in the wider focal lengths (lets take 18mm) you'll be able to fit all of A through H in the frame, however with a lens that starts at 120mm, you'll be lucky to fit just one or two letters in the frame. This is with standing at the same vantage point.
I really have no idea why I laid it out like that, just some weird urge. That's why I included the google link, to put pictures to ideas.
Hope that helped,
Bob
BTW- The minimal focal distance for the Sigma 120-400 is 4.9' (1.5 m).
