The all-new Nikkor AFS 80-400 mm f4.5-5.6 VR II ED G lens is the successor to the original version of Nikkor AF 80-400 f4.5-5.6 D VR first introduced in January,2000. It comes with a MSRP of $2,799. Compared to the current non-AFS version at $1,600 and the professional Nikkor AFS 70-200 f2.8 G ED VR II at $2,399, it is relatively expensive considering that the tripod collar
may be optional at extra cost.
From the available information to-date, the lens barrel differs from the professional grade 70-200 f2.8 with the use of polycarbonate material. There is
unconfirmed rumor that this lens may not even be "Made in Japan" compared to other professional lens line-up. However, from examining the MTF charts, the optical performance should be no less than stellar.
