How else would you explain the whole topic that you started?
Here's what I wrote to open the topic you just linked to:
"If Canon's new FF mirrorless camera does not use the old EF mount, would you continue to buy EF lenses?
Maybe wait a while to see how things play out?
Maybe wait for an adapter to be reviewed and have some time in the field?
Or do you believe a new FF mirrorless with a new mount would in no way affect the current dSLR lineup for many years to come?"
Many posters thoughtfully replied to the questions actually asked and helped me adjust to the transition--and I thanked them.
