Nikon D3 users can boost the flagship camera?s continuous shooting buffer memory by sending it off to Nikon for a £352 upgrade.

Nikon UK tells us the service turnaround time is 10 working days, provided that the parts are in stock.

Nikon adds that the upgrade is mainly aimed at sports photographers shooting in NEF file format.

The upgrade increases, for example, the number of continuous NEF (12-bit lossless compressed) raw files ? captured in a single continuous burst – from 18 to 43.
