If you want a quiet canon, then the Canon canonet range finder camera, 35mm film, 45mm f1.8 lens a auto function and film advance lever mounted on the bottom to give the camera a smooth look for the top. When they were first released in Japan they were supposed to have sold out within a hour and most importantly no mirror for silent use. Next it's little brother the Canonet Junior range finder with a 40mm f2.8 lens. Both cameras were noticeable by the light sensor mounted around the lens. Now if you want to look cool, this is the way to go. You may have the latest and modern digital camera, most people will think, Oh look a camera but a vintage camera like this will arouse interest.
