Summary: Overall the performance of this lens is very solid indeed: Nikon describes it as "the ideal walkabout lens", adding that it offers "maximum flexibility with minimum kit", and that claim definitely stands good.
Excerpt: Nikon has answered the call of FX (full-frame) camera users to provide a lens comparable to their ultra-popular NIKKOR AF-S 18–200mm f/3.5–5.6G VR II DX-format lens with their new AF-S 28–300mm f/3.5–5.6G ED VR.
Nikkor AF-S 28-300mm f/3.5-5.6G ED VR (FX) - Review / Test Report
24 February 2012
Conclusion: Distortion is very pronounced at almost any focal length, vignetting is somewhat on the high side, too, which is also true for CAs. Sharpness in the image center is good, but not great, especially towards the long end, and border and corners can be very soft at many focal length and aperture...
Excerpt: With the lens attached to a D700, auto-focus is generally fast (but not instant). On the F65, focusing worked well in good light, but became quite problematic in normal room lighting. The D700 had no such issues with the lens.

Conclusion: The main advantage of an interchangeable lens camera is obviously its interchangeable lenses, which theoretically allow photographers to use the correct lens for any specific subject or conditions.
Pros: Long zoom range, Effective image stabilization, Very sharp, Perfect for FX sensor bodies
Excerpt: Originally posted 2010-11-12 on Optyczne.pl In days of analogues amateur megazooms were relatively popular but then you could meet 28-200 mm more often than 28-300 mm class lenses. It doesn’t mean, though, that the latter were totally non-existent.
Cons: weak image quality on the edge of DX and full frame as well,, very high distortion on full frame,, high chromatic aberration at longer focal lengths,, significant coma in full frame corners,, noticeable problems during work against bright light.
