The terminology is confusing, talking about equivalent focal length on apsc blah....
Focal length never changes, it's a fixed property of the lens. What changes is how much of the image circle that the the lens projects into the camera is used by the camera sensor to produce the image. The smaller sensors use a smaller part of the image circle. So what you get is a narrower field of view than a camera with a larger sensor would get with the same lens.
