Nikon AF-S DX Nikkor 18-140mm f/3.5-5.6G ED VR
Image quality: 8/10
Value for money: 7/10
A consumer lens with a zoom ratio of almost 8:1 is never going to be as good in the optical department as primes or short-range professional zooms, and the Nikon AF-S Nikkor 18-140mm f/3.5-5.6G ED VR certainly doesn't challenge that paradigm. That being said, this lens still managed to exceed our expectations in terms of sharpness, particularly at the long end where many all-in-one zooms tend to suffer. Centre sharpness in particular is good to very good at all focal lengths, with the edges being quite decent too, especially stopped down to f/8. The lens is also very well corrected for chromatic aberration - you have to look real hard to find any trace of it, even along contrasty edges. Geometric distortions are slightly more prominent - especially the barrelling at 18mm - but are no worse that you'd expect of a lens of this class. Close-up performance, on the other hand, is nothing to write home about - with a maximum reproduction ratio of 1:4.4 and a close-focus point of 0.45m, the Nikkor 18-140mm f/3.5-5.6G ED VR certainly won't double as a macro lens.
