Cooke Optics has announced the acquisition of a majority stake in the company by Caledonia Investments PLC, a self-managed investment trust. The current Cooke Optics management team remains in place, and day-to-day activities at the Leicester-based company will continue unchanged. Cooke’s most recent developments include the S7/i full-frame lens range, which correctly anticipated the current large format trend; the Panchro/i Classic range, which replicates the look of vintage Speed Panchro lenses but with modern housing, mounts, and glass; and the Anamorphic/i SF range, which adds more exaggerated anamorphic attributes, including lens flare and oval bokeh. The company is also behind the lens metadata standard, /i technology, which captures valuable lens information for use on-set and in postproduction. Caledonia is a self-managed investment trust company listed on the London Stock Exchange with net assets of approximately £1.9 billion ($2.5 billion) as of June 30, 2018. The company maintains a concentrated portfolio of international quoted, unquoted, and fund investments and has paid an increasing annual dividend for 51 years.
