Q: 9. I am confused. If a full frame sensor is smaller than 645, shouldn't the effective focal length increase instead of decrease?

A: Typically, angle-of-view and focal length are described relative to full-frame 35mm as it is more widespread in use. Crop factors would be then be 1x for 35mm, 1.5x for APS-C, and 0.6~0.8 (rough estimate) for medium format sensors. Since this lens is still technically (from physical distance measured stand-point) 400mm from the sensor, it's a 400mm lens. However, its angle-of-view would be equivalent to a 315mm on a full-frame.
