Some people might not be aware that Tamron's largest shareholder is Sony. Which, in a very roundabout way, kinda means that Sony makes lenses for rivals like Canon and Nikon. However, that could be about to change thanks to "a massive capital upheaval, perhaps the largest since the company's founding".
For years Sony has owned the biggest share in Tamron, enjoying a 15.35% slice of the company as of December. But according to a report by Digital Camera Life, the second-largest shareholder – activist hedge fund investor Effissimo Capital Management – could might have muscled its way to a majority interest.
