SUMMARY
Canon Japan has officially marked the EF 100-400mm f/4.5-5.6L IS II USM telephoto zoom lens as discontinued on its online store. This move signifies a continued decline in new DSLR lens production as manufacturers focus on mirrorless technology. While this discontinuation is noted in Japan, the lens may remain available in other regions for a time. Canon's RF mount offers mirrorless alternatives like the RF 100-500mm f/4.5-7.1 L IS USM and the RF 100-400mm f/5.6-8 IS USM.
