From the many reviews I've read, The Nikon 17-35 2.8 was never stellar in the IQ department. Fast and great build, but I'll take IQ over that for my use. The new Nikon 18-35g is fantastic, sharp and contrasty. It's become my most used lens and as far as my results, it's a bargain at $750. It is more of a "prosumer" build, but has the rear gasket and it's a lens you can carry all day, extremely light. Yet another option for the sub $1k category.
