'Subsequent to the original Service Notice regarding a power issue with D5000 and the adoption of the preventative maintenance, an additional and enhanced procedure has now been developed,' says a Nikon UK spokeswoman. 'A small number of D5000 cameras were not initially treated with this enhanced procedure so we are asking customers to return them to us for a short time for further repair work.

She continues: 'The process of repairing affected D5000s is being handled in a fast and efficient manner and we are committed to maintaining this level of service so that the issue is fully resolved within the near future.'

Nikon recommends that all D5000 customers check the updated list of 'Affected Product Serial Numbers', as additional product serial numbers have been added.

Nikon adds: 'We sincerely apologise for any inconvenience that Nikon customers may experience as a result of this issue. Nikon remains committed to providing only the highest quality photographic products and hopes that you will continue to choose Nikon for your imaging needs.'
