When choosing a camera for street photography, consider factors such as size and weight, autofocus speed, image quality, and low-light performance. A compact and lightweight camera is ideal for mobility. Fast autofocus ensures you never miss a moment, while excellent image quality guarantees sharp, clear shots. Low-light performance is also important as street photography can often involve shooting in varying light conditions.

Both DSLR and mirrorless cameras can be great for street photography. It largely depends on your personal preference. Mirrorless cameras are generally lighter and more compact which can be beneficial for mobility in street photography. However, some photographers prefer the optical viewfinder of a DSLR which can make it easier to visualize the final image.

The lens is extremely important in street photography. A wide-angle lens is often preferred as it allows you to capture more of the scene. However, a prime lens with a fixed focal length can also be useful for its typically faster aperture and high-quality images. The choice of lens will depend on your personal style and what you want to capture.

While having a high-resolution camera can provide more detail and allow for larger prints, it's not necessarily essential for street photography. Many successful street photographers use cameras with moderate resolution. What's more important is understanding how to compose your shots and capture the essence of the scene.

A silent shutter can be a significant advantage in street photography. It allows you to take photos without drawing attention to yourself, helping you capture candid moments more effectively. Many mirrorless cameras offer a silent or near-silent shooting mode.
