A 35mm f/2 lens is a popular type of camera lens known for its versatility and sharpness. The "35mm" refers to the focal length, which provides a natural perspective similar to what the human eye sees. The "f/2" indicates the maximum aperture, allowing more light to enter the lens, making it suitable for low-light conditions and creating a shallow depth of field for beautiful background blur. This lens is commonly used in various photography styles, including street photography, portraiture, and landscape photography. Its compact size and lightweight design make it easy to carry, making it a favorite among both amateur and professional photographers.
