  1. SIGMA lens specifications (sigma-global.com), checked Oct 15, 2026

Worked out by code, not stated by a source

  • Focal length and widest aperture as the lens's own name states them.
  • Read from the lens name: each maker marks the sensor size a lens covers (Sony FE/E, Canon RF/RF-S, Nikon DX, Tamron Di III/Di III-A, Sigma DG/DC); every Fujifilm X lens is APS-C and every Micro Four Thirds lens is Four Thirds.
  • Read from the lens name: Sony marks optically stabilized lenses OSS, Canon IS, Nikon VR, Fujifilm OIS, Panasonic O.I.S., Tamron VC and Sigma OS; a lens from these makers without the mark has no optical stabilization.
  • Prime or zoom, read from the focal length in the lens name.
