Yes, the Nikon AF-S NIKKOR 105mm f/1.4E ED is a real lens. How many telephoto lenses beyond the 85mm focal length with an f1.4 aperture have you seen? The answer is probably very few, and if anything we’ve seen 200mm f1.8 lenses from Canon years ago. But the new Nikon 105mm f1.4 E lens is quite an interesting one. With 14 elements in 9 groups, 3 ED elements, 9 aperture blades, fluorine coatings and an 82mm filter size this is a very interesting and different lens from what’s been available and out there.
Of course, this lens is also designed for full frame DSLRs. Further, the Nikon 105mm f1.4 E ED is also not at all cheap: at $2,199.95 expect it to really only be used by professional portrait photographers.
