>>2874421Just set the iso to whatever your film is on the iso ring
As for focusing I'm not sure what the canonet viewfinder looks like but there should be a rangefinder patch in the middle that will look like a little discolored version of what you're looking at
Fiddle with the rocus ring while looking through the viewfinder and you'll know exactly what I mean and it's really easy since the canonet has such a short focus throw
Generally it's a good idea to focus on what you want and then frame and shoot
Good luck though the canonet is a great little rangefinder
