Leica

I managed to extract this out of the Leica beast and in Manual, but I need to explore the 250 pages on 'Instructions', to see if I can unravel the mysteries of controlling shutter speed. For those of you who like to know this is done at 5.6 and 1/80 sumhow !! 
Not reading instructions and impatience is certainly one of my failings I'll hold up my hand to.
