Nikkor AF-S 28-70mm f/2.8 D IF-ED (FX) - nhận xét / thử nghiệm Report
Lens review - Nikon / Nikkor (full format)

*
Review by Markus Stamm, published March 2013IntroductionIn 1999, Nikon announced the first zoom lenses with silent-wave AF-S drive. Unsurprisingly they introduced the then new giải pháp công nghệ into their high-end products first.One of these lenses is the Nikkor AF-S 28-70mm f/2.8 IF-ED, a fast standard zoom for full-frame cameras. It features the gold ring, indicating a professional grade Nikon lens. In 2007 it was replaced by the Nikkor AF-S 24-70mm f/2.8 G ED.In this review we"ll have a look at how the lens performs on our current FX chạy thử camera, the Nikon D3x.

The lens was targeted at professional users and consequently the build chất lượng is superb. Most outer parts are made of metal and carry the crinkle finish typical for professional grade Nikkor lenses at that time.The focus và zoom rings operate very smoothly and slightly damped. The lens has a reverse zooming mechanism. It extends towards the wide over of the range và the shortest physical length is reached at the 70mm setting. While this may seem odd at first, the system makes sense when attaching the deep hood which remains highly effective at all focal lengths. With attached hood, the form size of the whole package remains constant.Thanks to an IF (internal focusing) design the front element does not rotate, so using a polarizer is no problem.

As already mentioned, the lens features a silent-wave AF drive. Because of this AF-S motor, the lens provides very fast và near-silent AF operations as well as manual focus override at any time.In addition to lớn the dark finish shown above, the Nikkor AF-S 28-70/2.8 was also available in light grey colour.
