Nikon has announced a memory upgrade for its flagship D3 DSLR. The service, which is already available, will increase the continuous shooting buffer from 16 to 36 shots for those people shooting 14-bit lossless NEF raw files. In most filetype/compression permutations, users can expect to see around a doubling of shooting buffer. Owners wishing to upgrade are advised to contact their local service center. The price will be £300+VAT in the UK, and $500+tax in the USA.
