Below are the key points translated by Google.
1): AF, although Nikon new (E-type) is said to have become 50% faster, in the test, the new is a little fast, the difference is slight. Old AF is also fast, the difference in the AF speed of the old and new two lenses to be honest I do not know very well.
2): Camera shake correction in 1/8 seconds at the telephoto end, was a success rate of 60-70%.
3): Image quality (comparison of the pixel size of the 36MP machine), the center is pretty much the same for both of the lens, the corner is old sweet in the open, it’s new F2.8 the same level of image quality squeeze the old to F4. In F8 Both lens also a sharp, but still, it’s new is it slightly sharper.
4): The chromatic aberration of magnification, the old is also good.
5): Light falloff at edges, the new model is a 24mm open is a remarkable corner of the decline, rapidly peripheral light is reduced in the corner rather than gradually fall. Light falloff at edges did not improve even at the telephoto side, the new model is very noticeable at the time of opening, it’s above-average performance in the other aperture value.
6): Distortion, but the difference is not seen in the new and old at the wide angle end, towards the new is a large distortion at the telephoto end.
