It was inevitable, but it looks like Canon is starting the discontinuation of EF lenses. I was told by Alex at FStoppers that the Canon EF 200mm f/2L IS USM is now unlisted or listed as discontinued at various retailers.
While it is still listed at Canon USA, the lens is no longer listed at Adorama and shown as “discontinued” at B&H Photo.
I will be watching these things closely over the next few months. I suspect a lot of the older and older higher priced lenses such as the EF 800mm f/5.6L IS USM are on their last legs.
Update: Canon USA has confirmed that the Canon EF 200mm f/2L IS USM will have service support from Canon until at least December 31, 2027. If parts remain after that date, service will likely continue until that inventory is depleted.
