Last summer I had my Canonet set for indoor conditions at f/1.7 and 1/60th of a second. I accidentally left it on that setting and took a picture of a fish I caught outdoors during the day. By my calculations that's at least 8 stops of overexposure. I figured it was a lost cause but when I attempted to print it, I did get a picture that was recognizably a fish... I wouldn't recommend it unless you know what you are asking for; the picture was pretty grainy with cooked highlights but honestly a lay person would probably think it was fine.
