The Sony 200mm lens is a telephoto lens designed for capturing distant subjects with clarity and detail. It is often used in photography for wildlife, sports, and portraiture, providing a narrow field of view that helps isolate the subject from the background. This lens typically features a fast aperture, allowing for excellent low-light performance and beautiful background blur, known as bokeh. Compatible with various Sony camera bodies, it enhances versatility and image quality, making it a popular choice among both amateur and professional photographers.
