Stand 16.02.2015: The lens is still not suitable for pure JPEG photography in conjunction with the Nikon 5100. Background is that, contrary to the 'expectations' in the distortion correction update in September 2014 'Lost' this objective was, in the distortion correction 1, which must be used for the D5100 (distortion correction 2 is not compatible with the D5100). Read more at the Support page of Nikon. When I asked the Nikon Support I got the following answer: Regrettably update has not listed the 18-140mm lens from 01.09.14 in firmware. We also have no information about why that did not happen and if or when a fix for this objective in connection with the D5100 will be available. Therefore, I recommend you the distortion subsequently perform when using this lens with the help of software Capture NX-D, if you decide to buy this lens.
(Bzw.zusätzlich be taken in RAW format) Each image must be reworked: Does. Those like me who want to shoot a lot of out-of-the-box, for which the lens is currently unsuitable.
By the way, for the already somewhat aged D90, the distortion correction are used 2. Nikon fan that is absolutely incomprehensible to me why only 2 of 5 stars actually.
