SUMMARY
Sony currently holds the largest shareholder stake in Tamron, but this position may be challenged by activist hedge fund Effissimo Capital Management. Effissimo has significantly increased its ownership, now holding a larger percentage of Tamron shares than Sony. This move by Effissimo, known for pushing for corporate change, could lead to shifts in Tamron's strategy, potentially accelerating its expansion into ecosystems like Canon's RF mount. Despite the potential change in majority ownership, Sony is expected to remain a key partner for Tamron.
