600 Sony FE 600mm F4 GM OSS

The Sony FE 600mm F4 GM OSS is a prime lens for Sony E-mount (Full frame) that covers 600 mm at f/4, weighs 3040 g and focuses as close as 4.5 m. Brightest (f/4) and heaviest (3040 g) of the 3 full frame Sony E-mount prime lenses in its focal range. Among them, 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 brightness and reach.

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.
