  • Codec & Workflow: Internal ARRIRAW and Apple ProRes recording are the gold standard for high-end post-production pipelines.
  • Dynamic Range: 14+ stops of dynamic range provide exceptional highlight and shadow retention.
  • Built-in ND: Motorized FSND filters (0.6, 1.2, 1.8) simplify exposure control on set without external matte box filters.
  • Robustness: Designed for demanding professional sets, offering extreme reliability and durability.

GFX Eterna 55

  • Sensor & Resolution: Massive 43.8 x 32.9 mm 100MP medium format sensor captures breathtaking 8K (7680 x 4320) detail.
  • Dynamic Range: Class-leading 16+ stops of dynamic range for incredible latitude in grading.
  • Internal Codecs: Records internal ProRes and ProRes RAW, offering a powerful, flexible post-production workflow.
  • Modern Features: Electronic variable ND (0.6 to 2.1) and dual stabilization (OIS/DIS) enhance versatility on set.
  • Value: Delivers medium format 8K cinema capabilities at an MSRP of $16,499.95, significantly undercutting high-end cinema cameras.

The trade-off

Choosing the ALEXA Mini LF means sacrificing 8K resolution and modern conveniences like IBIS and autofocus, along with a significantly higher price tag. Choosing the GFX Eterna 55 means giving up the industry-standard ARRIRAW codec and ARRI's renowned color science, which is still unmatched.
