Pick the 20 mm if you need a wider field of view for landscapes, architecture, or tight interiors. Choose the 35 mm if you prefer a classic documentary or street focal length that compresses perspective and handles low light equally well. Both share the same price and maximum aperture, so the decision hinges solely on the subject distance you shoot from. Neither lens offers a clear technical advantage over the other.
