I just bought a V-Lux camera and I'm learning how to use it. I set it to AF-MF, so the zoom ring should become a manual focus after I've autofocused. Looking at the PDF manual, I think I've set this up right, but when I turn the ring, it does not seem to change the focus at all. Also, there is no 'focus highlighting' or focus assist, or a scale which shows me the general focus distance (close to far)--even though I think I've turned on these features as well. Can anyone give me some pointers as to how I can achieve what I want? I did by this 'open box' from B&H, which is like-new with warranty, but there could still be something not right. All the best, David.
