How the pick works

  1. Widest aperture3

    Lower wins once they are 0.3 apart.

  2. Weight2

    Lower wins from a 12% gap.

  3. Focal length (longest)2

    Higher wins from a 15% gap.

  4. Focal length (widest)2

    Lower wins once they are 2 mm apart.

  5. Optical stabilization1

    Having it wins.

  6. Closest focus, wide end1

    Lower wins from a 15% gap. Compared only between lenses of the same focal length (widest).

  7. Filter thread0.5

    Lower wins once they are 5 mm apart.

  8. Lead for a pick1

Our pick or our take adds up the importance of each real difference, with these importances and thresholds: a gap smaller than its row's threshold is too close to call and counts as the same. They are our editorial choice, not a measurement, the same on every page, and they never read prices, sales or who sells it.

Worked out by code, not stated by a source

  • 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.

Each value is checked automatically against the source it links, on the date shown. How we build these pages

† The makers' own tables, row by row, with labels in our plain words (translated where the maker's page isn't in English); each row's numbers are checked against the page it links.
