Nikon has revealed that it allocated ¥1.8bn (~ $17.6m / £10.5m) to cover the cost of warranty repairs and replacements for its D600 SLR in the last financial year (ending March 31st 2014). The camera has been plagued since its launch by a tendency to accumulate oil spots on its sensor, resulting in Nikon offering to replace the shutter mechanism or even the entire camera for free if necessary. In an investor relations statement on its website, the company says that it is taking the matter very seriously, and 'will be taking steps to restore confidence in the Nikon brand'.
