30 Sigma 30mm F1.4 DC DN

The Sigma 30mm F1.4 DC DN is a prime lens for Micro Four Thirds (Micro Four Thirds) that covers 30 mm at f/1.4, weighs 260 g and focuses as close as 0.3 m. Next to 5 other Micro Four Thirds prime lenses in its focal range, it suits you if you shoot in low light or want a blurrier background, or you want more reach at the long end. If you carry it all day or travel light, or you want to focus closer at the wide end, every other one that does better on weight, or close focus gives up brightness. If you want a wider view at the short end, every other one that does better on width gives up reach.

  1. SIGMA lens specifications (sigma-global.com), checked Oct 6, 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.

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.
