35mm half-frames are not 18x24 (the exact half of 24x36, but in general a little more than 17x24 because you need at least 1mm to separe two adjascent frames. It depends on the camera.

35mm

That's why I think we should not use the crop factor any more. We had all the different formats before and didn't need the crop factor. One thing I don't like about the crop factor because it makes the 35mm format as the one all other formats are measured by. I often joke that I only use full frame because I can't figure out the crop factor.
