Crop mode on Nikon FX cameras use only the crop area, discarding all pixels outside the crop. It is how they achieve a faster frame rate and smaller image size. If the camera had to capture the full sensor's worth of data, then process the image to "crop" it, the camera would be slower, not faster, though the buffer would take longer to fill.
exactly, that's why I listed it as an exception.
