An advert for a u2018D400u2019 camera guide that appears on Amazon was an u2018erroneousu2019 posting, says Simon Stafford, the photographer named as the booku2019s author.

Meanwhile, the publishing company behind the Magic Lantern Guides series has issued a statement, in response to speculation that Nikon may be poised to launch a new D400 DSLR.

Haley Steinhardt, editorial manager at Sterling Publishing, said: ‘Due to an internal systems error, the Magic Lantern Genie Guides book with ISBN 978-1454707820 was mistakenly listed with a fictitious model name: the D400.

‘This was a dummy title that never should have fed out to booksellers, and neither Simon Stafford nor Sterling Publishing Co., Inc have any knowledge of such a camera model.

‘Apologies for the confusion.’

Yesterday, a spokesperson for Nikon told Amateur Photographer: ‘Unfortunately, we are not able to comment on potential future product.’
