This patent application (Japan 2023-125903) has a lot of esoteric fast zoom lenses in some very nontraditional focal lengths. Many of the embodiments are missing the image height, however since we also have the half angle of view, we can work backward to verify if these lenses are meant for full frame or for APS-C.
