Basically, it really comes down to budget and what kind of photos she wants to take. You can get great results with a 500€ camera just as well as with a 2000€ one, depending on the use case.
I’ve worked with Nikon, Canon, and currently Sony, and all of them were great in their own way.
If you share your rough budget, people can probably give much better recommendations.
Think she went with Nicon and its probably a 700$ base. We have a few camera lenses shes going to try
So it we return it, about 700$
