Yes , I am thinking Superia , cheap and very high quality. I found that EOS 620 suggestion have a reason because it has 6 sensors in the camera , or they say segmented or honeycomb , I am 1930s rangefinder guy and have no idea about modern stuff. May be center weight is the best idea. I dont know if there is light meter sensor location difference between cameras. I had a Leicaflex and it has a light meter in the back middle of the mirror.
My reason is to open that thread , the knowledge between different bodies and their sensor placement.
And going from there.
