Tim Cook recently confirmed on Twitter that iPhones use camera sensors made by Sony. "We've been partnering with Sony for over a decade to create the world's leading camera sensors for iPhone," states the tweet by the Apple CEO.

The tweet was made to address Cook's recent visit to Kumamoto, Japan, home of many semiconductor firms. In the tweet, Cook also thanked Kenchiro Yoshida, CEO of Sony, for showing him around the "cutting-edge facility". 

According to a report by Reuters, Cook recently stated that for the last five years, Apple has invested over $100 billion in Japanese suppliers. The facility in Kumamoto is among the many Japanese tech suppliers that Apple has been in partnership with to create parts for their signature iPhones. 

Cook's sudden confirmation of using Sony camera sensors in iPhones comes as a shock to many Apple fans - especially considering how Apple usually doesn't disclose such inside information. While many dedicated users and loyal fans have previously suggested the use of Sony camera parts in past iPhones, there was reportedly no official confirmation until now.
