It is clear that you want a constant f / 2.8 zoom, but this is completely different money. Use as a universal lens for every day, as an adequate wide-angle - great. I use it on x-t3 and x-t30 As the only lens per system for serious use - not enough, but how wagon is great. In addition to it, you need something - fast aperture - either native optics or new Viltrox optics, or the same good Canon optics through an adapter.
