Well regardless, If I were OP, I'd wait a few months to see if the lens could be had for under $1900.
Edit: now that I think about it, I remember something funky happening with a price match, despite Amazon stating they don't price match. Still, the price would have been maybe 1800-1850ish.
Lowest price was ~$1975. With cash back or amazon goldbox, around $1900 (except special cases due to somebody messing up or a combo deal with a camera). After using and thoroughly enjoying the lens for a year and , maybe starting to forget the hefty price tag!
