As far as the meter is concerned, look at the sites provided in one of the preceeding posts - while I do not have experience with your particular camera, I have had a wein cellin a Canonet QL17, and been very happy with it. It is a bit more expensive, but it may be an option to the adapters, depending on how much you use the camera (the downside of Wien cells is that they deteriorate without use much faster than regular bateries unless the air-holes are covered)
