The original statement was, "...the EF-RF adapter adds 110grams to those EF lenses when used on an RF body."
You do understand that adapters, when used on an RF body, are used without the caps, right? Kinda hard to mount the lens to the adapter or the adapter to the body with the caps on the adapter.
So you do understand that when one is considering the extra weight added by using the adapter to mount an EF lens to an RF body, it's the weight of the adapter, without the caps, that is the relevant measurement?
Geez, I really didn't think anyone could be that daft. I was wrong about that.
