Pick the Sigma 14mm if you need an ultra-wide prime for landscapes, architecture, or astrophotography and prioritize a brighter f/2.8 aperture at that focal length. Choose the Tamron 35mm if you prefer a standard prime with a faster f/1.8 aperture for low-light shooting, portraits, or street photography—and don’t mind its significantly heavier build. Both deliver equal value at this price, so the decision hinges solely on focal length and aperture needs.
