Yes, the "new" 1.4 / 50 AF-S is the capacity (even) better than the older AF-D. Even if the plastic material used comes right wertig at first sight, the lens turns out to almost three years (professional) use as a fast expendable. That the attached Goldschriftchen (Kitsch) pretty rub, is bearable but unpleasant. A sloping thin plastic ring from the tube is already annoying and not the standard that I expect the brightest 50 Nikkor. Yet another year's service and I can dispose of the plastic thing probably. By the way: the rubber coating of the focus ring is dropped before and had to be re-glued. Qualitatively no comparison to my AF-D lenses (1.4 / 50 and 1.4 / 85), which are built to last and to - in spite of "crank autofocus" - also focus twice as fast ...
Love Nikonians: Please builds but a high-quality 1.4 / 50 magnesium, and equipped the thing a useful quick AF. But I spend also at 250 EUR More than this plastic part.
Four stars I forgive for good imaging properties of the lens, only one for the type and the grotto slow AF.
