Coverage

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
  • Period work and romantic texture
  • Faces that should feel imperfect and lyrical
  • Projects embracing flare and lower contrast
  • Small mirrorless narrative rigs
  • Lightweight companion cameras in Cooke packages
Tradeoffs to test
  • Consistency varies by rehousing and set matching
  • Not the right choice when VFX or sharp technical reproduction dominate
  • The maximum aperture is T2.4.
  • Mount and M-mount compatibility must match the camera; this is a mirrorless lens family.
