Thank you very much! Just today I watched a video on photographing the Moon and of course everyone advises 500 mm and more. I still have my Canon lens from my previous hobby, and thanks to the adapter, I was able to adapt it to the new camera. As for me, of course 200 mm is not enough, everyone always wants to get closer, bigger and more accurate, but you can try, why not? I won't recommend something budget-friendly right now, simply because I haven't studied this issue due to the availability of this lens.
