Seán MacKenna photographed and digitised the production records of the Dallmeyer Lens Company, which are held by the Brent Archive (who continue to hold the copyright), over a period of several years with the view to make these records available to all photography enthusiast. This was still a work in progress at the time of his death in October 2012 and this website is based on the records that he left.
