Look and character

With a 1.8x squeeze, the image is optically compressed horizontally by 1.8× and stretched back in post. That gives these desqueezed aspect ratios, by recorded area:

  • 16:9 sensor area → 3.20:1
  • 3:2 sensor area → 2.70:1
  • 4:3 sensor area → 2.40:1

Horizontally, a 135 mm 1.8x lens covers roughly the width of a 75 mm spherical lens on the same format (focal ÷ squeeze); vertically it stays 135 mm.

Flare: Blue. This comes from manufacturer information; we have not shot with this lens ourselves.
