Yeah when I realized I needed to clean it, I had to watch some videos to learn how.
I didnt want to make any mistakes. To be honest it was very simple, you only put enough pressure to slightly bend the stick and slowly move the cleaning end in one direction.



Youre going to love that camera. I would say that any camera released after 2018 is still a very capable camera even today.
If you havent learned it yet, the expsoure triangle is the most important thing to learn imo. After that is composition and lighting.
I would personally only clean the sensor when it needs it. The less you touch the actual sensor the better.
Good luck!
