Discontinuing all EF lenses is a really bad idea from Canon. There are a lot of lenses that could be improved. I'm pretty sure that an EF-S 60mm f/2.8 IS USM Macro would be welcomed by a lot of people. Ok, discontinue the first two version of any lens that has a third version or the first if there's a second one. But the RF mount versions of the lenses are a totally diffrent system despite of the converters. So Canon should keep developing EF mount lenses for those who don't want or can't change to mirrorles cameras. Let's hope that Tamron and Sigma won't be this stupid and will develop EF mount lenses in the near (and not so near) future.
