When choosing a DSLR camera, there are a few things to consider. First, what type of photography are you interested in? Are you looking for a camera with a lot of features and manual control, or are you looking for something more basic and user-friendly? Second, what is your budget? DSLR cameras range in price from entry-level models to professional-level models. Third, what kind of lenses do you plan on using? Different cameras have different lens mounts, so you'll need to make sure the camera you choose is compatible with the lenses you plan on using. Finally, what type of features are you looking for? Different cameras have different features, such as image stabilization, auto-focus, and image quality.
Based on your needs, some good options for a DSLR camera include the Canon EOS Rebel T6i, Nikon D3500, and Sony Alpha a6000. All three of these cameras have great image quality, a range of features, and are relatively affordable. They also have compatible lens mounts and have an array of lenses available.
