The Canon Rebel T6s, also known as the EOS 760D, was developed by Canon Inc., a Japanese multinational corporation specializing in imaging and optical products. It was officially announced in February 2015 as part of Canon's entry-level DSLR lineup. The development of the camera involved contributions from various teams within Canon, including engineers and designers, rather than a single inventor.
