Nikon publicly announced that in the previous financial year (which ended on March 31st, 2014) ¥1.8 billion (approximately $17.7 million, i.e. £10.5 million) had been allocated so as to meet the cost of repairs and replacements under guarantee for its model Nikon D600.
Since its introduction, this DSLR camera has had problems owing to its propensity to produce oil spots on the sensor, which prompted Nikon to offer the replacement of the shutter mechanism or even the entire camera, of course for free, should that be necessary. In their explanatory statement on their official website, the company Nikon cited that this problem had been approached directly and professionally, and that they would "be taking steps to restore confidence in the Nikon brand".
