Take a piece of paper and draw a straight line on it. Now put a dot 50mm (or 2 inches if that's easier) from it. Now mark 36mm (or 1.5 inches) on the base line. Draw a line through the dot from each end of the 36mm line. This is the horizontal angle of view of a 50mm lens on a 35mm camera. Now extend that 36mm line out both sides to be 54mm in total. Now draw lines through the dot as above. This is the horizontal angle of view for a typical 6x6 MF camera 50mm lens. Notice that it is wider. Try other focal lengths. Or draw lines parallel to the 35mm ones and discover that they coincide at about 80mm.
I'm confused on how to draw this up - it's not super clear to me. I put a dot on a piece of paper and from that dot extend a baseline 50mm long? And then what - sorry I tried to understand what you meant but you gave vague instructions how I read it. I would really like to understand why MF and LF camera require longer focal length lenses that end up producing wider images than their 35mm counterpart. If you could draw this out for me, I would really appreciate it - if it's not too much trouble. It'd help me to follow along with the drawing to understand what's happening.
