One more question. My daughter has an iphone 7 that she uses now to take pictures. All she has specifically asked for is a camera that can take better pics than her phone. She likes taking headshot/modeling photos and nature photos. Not really into action shots. Are these SLR cameras the type you would go for? Or would a digital camera work for her? What about mirrorless? I really know nothing about this stuff and the research seems to be endless.
