Look and character
With a 1.5x squeeze, the image is optically compressed horizontally by 1.5× and stretched back in post. That gives these desqueezed aspect ratios, by recorded area:
- 16:9 sensor area → 2.67:1
- 3:2 sensor area → 2.25:1
- 4:3 sensor area → 2.00:1
Horizontally, a 75 mm 1.5x lens covers roughly the width of a 50 mm spherical lens on the same format (focal ÷ squeeze); vertically it stays 75 mm.
Flare: not documented in our data yetverify. This comes from manufacturer information; we have not shot with this lens ourselves.
