Hi! I own and use the 24 TSE Mk2 and various Zeiss wides and they're blisteringly good, and I don't have such flare issues. Shooting into light is always going to cause some flare potential. Try polarising it too, or using a ladder to give you more height to make the angle of reflection less acute and more obtuse. But various top German optics definitely do flare less because they are designed to. Determine your needs, do your desk research and if quality is important, then invest in your future.
