New lense, or new body for equestrian sports photography?

[giselle1]

Hi Everyone, thank you for any advice. I shoot sports photography, only horses, show jumping, dressage, western disciplines. I have no specific preference but mainly stick to my ponies and occasionally equestrian products. I have the EOS M50 Mark II with 15-45mm and 55-200mm lenses from the bundle. Videos are good but lack clarity; understanding manual settings might help. Should I upgrade the lens or the body first? I want better image quality and zoom for videos, while staying safely away from subjects within a budjet of around 1000. I’m considering the RF 100-400mm f/5.6-8 IS USM lens first (maybe the 24-240mm). Any advice? My plan is to buy a better lens rather than a better body, but I like my current camera and don’t use many of its buttons so I don't think I would want a new one.

Would also love any advice on understanding manual, when I upped my shutter speed it went full blurry before i even captured the picture.

Your camera system has been discontinued. RF Mount lenses are INCOMPATIBLE with EOS M series cameras. No such adapter exists to make this work. Canon used to make an adapter to adapt older EF/EF-S lenses. But that is also discontinued system. Yes used lenses can be found but support is at its end for most EF/EF-S lenses.
