You just need to learn how to use the standard modes and hold your hand firmly when shooting, at the far end (135) preferably with an emphasis. For lovers of home shooting, a good flash is still useful, for video an external microphone. For unusual shots - a polarizing filter. + a second battery if you forget to charge the first one. Portraits require good lighting. If you need very detailed portraits in the half-light, a flight of a ball in a video or a dragonfly, a bud like in a herbarium and a bug on the scale of a tank, then all this has already been shot by professionals many times and this is completely different money. This camera gives many opportunities: children's party, guests, tourism. And many interesting pictures are taken on a smartphone.
