This lens is a Nikon 70-300mm f4.5-5.6 G VR. It got launched into the market around 2006, covers the FX frame and has second generation VR. I guess the question is, "is it good enough to use in place of the much more expensive Nikon 70-200mm models?" Of course everyone's lens use will vary and some readers will have very high standards for imaging output while others will be more than satisfied at the performance. That's just the way the granulated market falls out.
Will it be sufficient for nearly every use we would normally have for this lens's faster and pricier brethren?
I've used a number of f2.8 telephoto zoom lenses that fall into the range of 70-210mm. I owned the Sony Alpha series version as well as the Sony Alpha f4.0 version. I've owned a number of Nikon 80-200mm f2.8's (both push pull and dual ring) and I've owned versions of each from Canon). In every case, if you desperately need that full f2.8 aperture
