Notable Features

• • Extending Barrel: Unlike internal-focusing lenses, the inner barrel extends significantly during close-up focusing.
  • Focus Limiter: Includes a physical switch to restrict the focus range, which speeds up autofocus when you aren’t shooting at extreme close-up distances.
  • Build Quality: Features the robust, “crinkle” matte finish typical of Sigma’s EX series with a high-precision brass mount.
  • Full-Frame (DG): Designed for full-frame cameras but works as a ~105mm equivalent on APS-C Sony bodies.
