Optics and imaging giant Nikon will stop making new single lens reflex cameras — once the technological mainstay of professional photography. Nikon will continue to produce and distribute its existing SLR models, but will focus development of new models entirely on mirrorless. Nikkei notes that Nikon’s SLR cameras were “widely used by professional cameramen for more than 60 years and have come to be seen as synonymous with the Japanese company.”
