filter/s is not necessary for good photography as good photography can be achieved without the use of a filter. however, a filter/s can help enhance or create effects. an analogy that comes to my mind now is: is the use of toothpaste necessary for brushing one's teeth?
For beginner, u dont need to worry too much abt filter really. I suggest u learn to use the camera as it is, and maybe get a simple prime lens, eg 50mm. Then take some photos and show us your photos and we will advise u what to do next.... :sweat:
