Thank you for the explanation, Andrew. Makes sense to me now 🙂
@ Jon
One classic Leica bodies, the shutter speeds get higher as you turn the dial clockwise. The opposite is true on the M6TTL, M7 and M8. I like the M6TTL shutter dial direction better because you turn it in the direction indicated by the over/under exposure indicators in the viewfinder to get the correct exposure. With the M6 classic, you turn it in the opposite direction.
