It’s a myth that a “real” camera instantly makes all photos better. Sure, there are some photographs only possible with big lenses and a real camera, but these situations are less common than you’d think.
A good photographer can take award-winning photos with whatever camera is available. Or to put it another way, your photos aren’t going to get better just because you have an expensive camera. Anyone can make sounds with a guitar, but you have to learn how to make music with it, and it takes a lot of work to master it. A camera is the same.
Before you spend money on a new camera, try improving the photos you take with your current camera or phone. You may be happy enough with the results that you’ll skip the new camera completely.
