Patent: Canon presents some fascinating quick zoom lens optical formulation | Canon Rumors

Then maybe be particular….
I count on what you need to occur to happen by 12 months 2024 after I count on the EF system to stop manufacturing.
My guess is your needed consequence will come out by 2024 when the EF system ceases being produced.
On condition that EF system will probably be phased out by mid 20s

I haven’t got a problem with Canon selecting to stop manufacturing or scale back the variety of EF lenses they actively promote however they are going to be that can be purchased for a very long time to come back. There simply is not any clear motive to cease if Canon continues to be making a living from them.
Their R&D prices have been amortised to zero (besides perhaps the EF400/600mm)
There should not be any manufacturing studying curve for his or her manufacturing value
Components prices ought to have been optimised by now however provide points may impression this

Canon has and can shock me and others with their selections when it did not appear logical to us however they have not (to my information) given any timeline indications for phasing out or stopping EF manufacturing.

Are you able to level to knowledge for the nations which have stopped importing EF lenses? They might have already got extra inventory readily available to cowl guarantee and repairs however that will usually be at a person lens stage. EF-S lenses have lowered in vary however are nonetheless important while APS-C DLSRs are being bought and are the one possibility for UWA (tailored) focal vary for the R7/10 in the present day.
