The only caveat is you must set the f stop on the lens ring and then the body electronically so they match as there is no communication between the two whatsoever. I do this often. You must also have that particular lens entered in the menu system and select it befor shooting. But that is not an issue as you simply select that lens as the one you are mounting before use. It’s not a big step. Just pre enter up to 9 early lenses in the menu and then you can turn a dial to the one you are going to use. It works fine and is just one easy extra step.
