Canon RF 400mm and 600mm Lenses Rumored for May Release

Canon RF 400mm and RF 600mm lenses

New Canon super telephoto lenses, specifically the RF 400mm and RF 600mm, are rumored to be hitting shelves in May. This report from Canon Rumors suggests these optics will serve as a refresh of the beloved ‘Big White’ series.

If the rumors hold water, photographers waiting for updated glass in the RF mount have a specific release window to mark on their calendars. The focal lengths of 400mm and 600mm promise to fill gaps between existing options without necessarily replacing current models entirely.

Canon Rumors frames this drop as an evolution rather than a total overhaul, hinting that key design elements from the legacy ‘Big White’ might survive while internal optics get a modern update. That approach could appeal to pros who need reliability alongside performance gains.

Take this with a grain of salt, but the timing aligns perfectly with Canon’s usual pattern of refreshing their high-end telephoto lineup after several years. We are expecting details on pricing and weight soon if these reports are accurate.
