What camera setup for holiday in Namibia?

Good day everyone

I am relatively new to photography. This July I am going on holiday to Namibia. I am looking for a camera that I can use there but also outside the holidays. I need the camera mainly for travel photography for family photos/photos of families, cities, for landscapes, but also often for wildlife like birds and other animals (giraffes, hippos, etc.) in Namibia. The camera should not be too heavy and big. And besides the standard lens, it should also have a telephoto lens for wildlife.

But now to my question. I won a CANON EOS M50 Mark II including the two lenses EF-M 15-45mm IS STM + EF-M 55-200mm IS STM in a competition. Hence my question. Is it worth trying to sell this camera now and then buying a new system? Should I just buy a new/used lens and sell an old one? Should I buy a teleconverter? Do I not need anything new at all? What do you think is the best way to do it?

I don't want to spend a lot of money on this camera (or the profit from selling it). If possible under 300-500$.

Greetings and have a good evening,
Luca

I went to Etosha in Nambia a couple of years ago and used a Canon 7D with 17-55 f2.8 and EF 100-400L, which worked quite well. There were times when I could have used some additional reach but overall I was able to get the shots that I wanted.

Thanks! So would you rather recommend the Sigma 150-600mm or the RF100-400mm?

Are you considering one of the R bodies? I would imagine that you would be happy with any of the R bodies, maybe especially one of the crop bodies. I could make a easy case for either the R7 or R10 and the RF 24-240 + RF 100-400 and maybe the RF 1.4x in there. If you want to keep costs down, it might be reasonable to rent.
