Hi , bought a Konica 50mm lens, and tried in in M Mode on my G5. I use the scroll wheel to find the correct shutterspeed . However , per accident i used this lens in A Mode , and it seems to work correct , camera selects ISO and shutterspreed , i only have to focus manually. Much easier than in M mode ! Is this normal that i can use ADAPTED LENS in A Mode (and S mode) ??
