@Steve and other users of the Z600 f/4 TC. I just got one this afternoon and I have a question. Page 34 of the reference guide says to ensure correct exposure etc. to not use the tc switch while any of he following are in progress. auto focus, vibration reduction, exposure. Seems a little confusing especially not using the VR. I would guess I can have vr turned on but not actively focusing or shooting ? Or are these just warnings that x might happen.
