In addition to the upcoming D4s and D810 UK price increase, the price of most lenses is rumored to go up by 5%-20% in early 2016. For now the info I received is only for the UK, I am not sure if the same will happen to other European countries.
If you need a new Nikkor, it is a good idea to order it before the end of the year. Check out the latest Nikon prices at Wex Photographic, Jessops, Calumet and Amazon UK.
