For image quality:
The images are very sharp, slightly easing in the peripheral areas even at open aperture 1.8 in the center. One hides but on 2.5 - from 2.8, you get a really exzelllente quality across the entire image area, the lens one looks in vain for a "Super Zoom". Distortion and vignetting can not be seen in practical operation.
Through the phenomenal resolution, it is thus possible to exhaust the current resolution DSLRs. The clarity and resolution makes it possible to create images of targeted Auschnittsvergrößerungen. The enormous for this price luminosity makes the Objetiv the ideal companion for available light photography.
Small pinhole can be personalized with the lens objects very nice release. Thus, even portraits are an ideal application.
The Bokeh is very "pleasant" and soft drawing.
The built-in autofocus is very fast, quiet and accurate. Schön is the ability to autofocus override manually at any time, at any time to retain full control over the image sharpness even in difficult situations. Since the ultrasonic autofocus is fitted in the lens, as opposed to the Nikkor 50mm / 1.8, the use of the Nikon entry-level DSLRs (D40, D60) is easily possible.
The CAs are addressed by design in the laboratory test offesichtlich higher than the 50mm / 1.8. In practice so far I could not confirm this.
The only "disadvantage" on the lens is that you actually want to use any other lens more and draws really> 90% of all pictures with this lens. Through the good price-performance ratio, the lens is ideal for "fixed focal length entry", you will thus quickly realize why these lenses are superior super zoom. The lens really has what it takes to "Always top".
