Coverage

Super 35

Cooke specifies a maximum format diameter of 30mm. Confirm sensor-mode coverage, especially for larger Super 35 gates.

Super 35

The referenced TLS set spans 18-100mm. Old Fast Glass lists Super 35 coverage on 18/25/32mm and larger coverage on selected longer lenses. The 40mm requires an aspect-ratio crop on ALEXA LF; verify the exact lens and sensor mode.

Use cases
  • Character-led drama
  • Faces and practical-lit interiors
  • Projects that want warmth without going full vintage
  • Period work and romantic texture
  • Faces that should feel imperfect and lyrical
  • Projects embracing flare and lower contrast
Tradeoffs to test
  • S35-only coverage
  • More veiling glare and slightly less bite than top-tier modern lenses
  • Consistency varies by rehousing and set matching
  • Not the right choice when VFX or sharp technical reproduction dominate
