The final Photokina under the then-current biennial cycle took place in 2018. Initially, the promoters planned to start a new annual cycle in 2019, with future shows to be held in May, but they later decided not to begin the new annual cycle until 2020. The worldwide outbreak of the Coronavirus disease 2019 and its effect on the imaging industry made koelnmesse decide to cancel both Photokina 2020 and Photokina 2021. Many photographic and imaging companies introduce and showcase state of the art imaging products at Photokina.
