18-140mm VR is a pretty new lens so I didnt get to see a lot of info on it.Is the 18-140 on par in terms of image quality with the 16-85 and 24-85?
^^This^^ Under good conditions, it will be almost impossible to tell whether it was a top-end or consumer-grade lens. What one is paying for when one pays $1500 - 2500 for a zoom lens is a large, constant aperture (f2.8 from one end to the other not, f4.5 - 6.3) better coatings so that you have less CA and ghosting, and more attractive flare. Remember that even the lowliest of lenses, the 18-55 has millions of dollars of R&D behind it, and is, in the proper circumstances, a very capable piece of glass!...I made a little test with my buddy, we were on a trip both using our D7100. I had my Nikon 24-70mm 2.8G and he had the kit lens 18-105mm VR and we used the lenses and swapped them.
When I got home I honestly couldnt tell if the pictures I saw were made with the 18-105mm or the 24-70mm.
But there was plenty of light and most shots had fast shutter speed and 100ISO
Absolutly, for me the true magic of the fast zoom lenses is their flexibility and not so much their IQ.^^This^^ Under good conditions, it will be almost impossible to tell whether it was a top-end or consumer-grade lens.
