Canon like most camera manufacturers have discontinued DSLRs and EF/ EF-S lenses. I would highly recommend moving to the RF Mount its the future the EF Mount isn't. If you can't justify the EOS R6 (I'm assuming the version II) look into the EOS R8 instead. Mirrorless cameras have much better AF in low light compared to DSLRs. What lenses do you currently own please provide the FULL NAME NOT just saying "EF 70-200mm F/2.8" IS NOT a complete name. Canon has made multiple lenses with that name. Also any EF-S lenses you own won't mount a Full Frame DSLR such as the EOS 5D Mark IV. I have posted example pictures below to help identify all of the lenses you currently own. If adapting EF lenses to RF Mount cameras stick with the Canon Brand EF-RF Mount adapters. 3rd Party Mount adapters are nothing but trouble. Also 3rd Party lens compatibility is up the 3rd Party Manufacturer NOT Canon. Do you own any accessories such as a speedlite (external flash) or battery grip if so list all of them.
