Nikon prices in the UK are to increase by an unspecified amount – probably at least 10% – with effect from 1 August 2016. This is inevitable due to the fall in value of the £ relative to the Japanese Yen.
Items which are in stock up to 31 July should remain available at the current price. However beware of ordering anything now which might not be supplied until 1 August or later, as you will probably have to buy it at the new price.
If you’re thinking of buying any Nikon gear this year, you’d probably be best locating a dealer with it in stock as quickly as possible, before stock runs out.
No doubt Canon, Olympus, Fuji, and other photo equipment will do the same, at about the same time.
