Surprisingly, I actually ordered one myself - I didnt think I even cared about this announcement at first nor am I usually an early adopter. But, I recently picked up a 7D that Im not exactly "in love" with and since Im not a big fan of uber-thin DOF for family photos etc, Ill no longer need my 85 1.8 when I have this lens. That should soak up the majority of the cost.
Since Im primarily a landscape shooter, having this prime like IQ in a 24-70 zoom (my bread and butter focal lengths) is fantastic. The weight savings over the current one helps for hiking in and out and I dont need IS since most of my shooting is done off a tripod. Seems like a deal made in heaven for a guy like me.
BH wont charge my card until April so Ive got until then to re-consider and review the data/images released in the meantime - at least Im on the list today.
