Each camera type has specific pros and cons. DSLR (digital single-lens reflex) cameras use a single lens, manual controls, and large sensors, but can be bulky.
Lastly, there are action cameras, which are waterproof and can capture video footage during outdoor activities. However, they don't have the best battery life or audio quality.
A key factor that affects an image's sharpness and detail is the sensor size. A larger sensor allows for larger individual photosites, essentially capturing more detail.
Larger sensors also offer better performance in low-light conditions. Full-frame sensors, the largest type, are usually only available in advanced, professional-grade cameras.
Cameras have interchangeable or fixed lenses, with the latter including zoom or prime lenses. Zoom lenses allow you to adjust focal length without swapping the size.
Prime lenses have a fixed focal length, meaning you cannot zoom in and out, and interchangeable lenses can be attached or swapped out for different lenses when needed.
Beginners may opt for a mid-range DSLR camera, while professionals require access to large sensors, a higher megapixel count, the ability to change lenses, and other features.
