TOKYO, July 30 (Reuters) - Japanese camera lens maker Tamron said on Thursday it has received an acquisition proposal ‌from Sony Group and that it has established a committee to ‌review its options.

The optical components manufacturer said in a statement that Sony made a ​non-binding proposal for a series of transactions to turn it into a wholly owned subsidiary. Tamron did not disclose the financial details of the proposal.

Tamron shares were untraded with a glut of buy orders on the Tokyo ‌stock exchange and looked ⁠set to close limit-up. The company had a market capitalisation of $1.18 billion as at Wednesday's close. Sony's shares ⁠were down 0.3%.

A Sony spokesperson said the entertainment and technology conglomerate believes the proposal will enhance Tamron's corporate value and the interests of its stakeholders, ​and contribute ​to the development of Sony's imaging ​business.

Sony is a leading manufacturer ‌of cameras and image sensors, while Tamron is a supplier of lenses for cameras made by Sony and rivals Nikon and Canon.

Sony owns 14.7% of Tamron, LSEG data showed. Singapore-based Effissimo Capital is the largest shareholder with 17.4%.

Tamron, which was founded in 1950, reported operating profit fell ‌13% to 16.7 billion yen ($102.15 million) in ​the year ended December 2025.

Shares in Sony ​have been under pressure ​in recent months as investors worry about supply chain ‌disruption and the impact of artificial ​intelligence on its entertainment ​business.

Sony is expected to be a major beneficiary of the launch of the highly anticipated video game "Grand Theft Auto VI", which is ​set for November, but ‌is grappling with the high price of memory chips.
