Ease of Use
The Nikon 18-140mm VR lens mounted to a Nikon D7100 body
Tipping the scales at 490 grams, the AF-Southward DX Nikkor eighteen-140mm f/3.v-5.6G ED VR is not a particularly heavy lens, and it balances well on the larger DX bodies such as the Nikon D7100 pictured above.
Build quality is very decent, with a metal bayonet mountain, smooth focus and zoom rings, and very lilliputian wobble even when fully extended.
Zoomed out and zoomed in
Zooming is not internal – as you lot tin can see, the forepart extends considerably upon zooming to 140mm. The ribbed zoom ring is sufficiently wide and neither besides stiff nor as well loose.
The Nikon xviii-140mm VR lens has a limited characteristic set including an internal focus (IF) mechanism, a quiet focus motor, an auto/manual focus switch and Nikon's Vibration Reduction (VR) image stabilisation system. There is no distance calibration, focus limiter or depth-of-field scale, all the same, and yous practise non get to choose between Active and Normal VR modes, either. Beingness a G serial lens, the Nikkor 18-140mm f/3.5-5.6G ED VR also lacks an aperture ring.
Side of the lens
The AF-S DX Nikkor 18-140mm f/3.5-5.6G ED VR comes without a lens hood as standard, but is uniform with the separately sold Nikon HB-32 petal shaped hood.
Rear of lens, isometric view
The lens is not claimed to be weatherproof, but at that place is a safe seal around the lens mount that should provide basic protection confronting dust and moisture.
Focal Range
At the 18mm terminate of the zoom range, the angle of view is 76°, equivalent to that of a 27mm lens in a 35mm system..
Field of view at 18mm
At the 140mm end, the angle of view narrows to 11°, which is the aforementioned every bit that of a 210mm lens on a 35mm full-frame photographic camera.
Field of view at 140mm
Focusing
With the lens attached to a D7100, auto-focus is surprisingly fast. While not quite in the same league as the pro zooms (due east.chiliad. the AF-S 24-70mm f/2.8 or lxx-200mm f/two.viii), it'due south definitely capable of keeping speedily and erratically moving subjects in focus. If you thought this was a natural consequence of existence an AF-S lens, think again! The AF-South designation, in and of itself, is no guarantee of fast focussing, as we saw when reviewing the 55-300mm f/iv.five-5.half dozen DX telezoom. The fact that information technology worked and then well in the case of the DX xviii-140mm f/iii.5-5.6G ED VR was thus a very pleasant surprise. (Focusing in Live View or video mode is a completely dissimilar story of course.) Thankfully the filter thread does not rotate on focus, making information technology that much easier to use graduated neutral density filters and polarisers. The lens takes 67mm filters.
Transmission focusing is also possible via the smooth but somewhat narrow focus ring located close to the lens mount. For an AF lens, the focus band has a fairly generous amount of travel, which makes it easier to set focus precisely.
Baloney
At the 18mm setting, there is some barrel distortion, every bit demonstrated in the photo above. This turns into mild pincushion distortion in the telephoto range.
Chromatic Aberrations
Lateral chromatic aberrations, typically seen as majestic or blue fringes in the peripheral areas of the epitome, are very well controlled with this lens. The 100% crops below give you an thought of what you should expect in the worst case.
Macro
This is non a macro lens. The maximum reproduction ratio of the Nikon 18-140mm VR is approximately 1:iv.4, which means that y'all can fill up the frame with a subject that measures around 100x67mm. Sharpness in the close-up range isn't stellar but distortions are negligible if shooting at the 140mm terminate. The following image illustrates how close yous can get to the subject; in this case, a Meaty Flash card.
Close-upwards functioning
Bokeh
Bokeh is a word used for the out-of-focus areas of a photograph, and is usually described in qualitative terms, such as smooth / creamy / harsh etc. In the AF-Due south Nikkor 18-140mm f/3.5-5.6G ED VR, Nikon employed an iris diaphragm with seven blades, which has resulted in a somewhat "nervous" bokeh, at least in our opinion. Still, recognising that bokeh evaluation is subjective, we accept provided a few examples for your perusal.
