I’m looking forward to getting the new Nikon f1.4G AF-S lens later this week from B&H in New York. There’s supposedly an improvement in sharpness, particular at the wide open apertures where I shoot most of my work compared to the older and beautiful ’50mm f1.4 D’ lens. Check out this review from Ken Rockwell http://www.kenrockwell.com/nikon/50mm-f14-afs.htm
If anyone is interested in buying the ‘D’ lens, please email me. The lens is in excellent condition and about 4 years old. Includes a filter, original packaging and metal hood which was purchased separately.
