100 Sony FE 100mm F2.8 Macro GM OSS

The Sony FE 100mm F2.8 Macro GM OSS is a prime lens for Sony E-mount (Full frame) that covers 100 mm at f/2.8, weighs 646 g and focuses as close as 0.26 m. Next to 10 other full frame Sony E-mount prime lenses in its focal range, it suits you if you want more reach at the long end, or your body has no in-body stabilization or you shoot handheld video. If you want a wider view at the short end, look at the Sony FE 90mm F2.8 Macro G OSS. If you shoot in low light or want a blurrier background, every other one that does better on brightness gives up reach and stabilization.

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.
  • Prime or zoom, read from the focal length in the lens name.

  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.
