Panasonic Lumix S5 IIX

What works

  • Apple ProRes 422 HQ internal recording — professional editing codec
  • ProRes RAW HQ and BRAW via HDMI to external recorders
  • V-Log L with wide color gamut for extensive grading latitude

What doesn't

  • 24.2MP sensor trails A7 IV for stills-heavy work
  • L-mount lens ecosystem smaller than Sony E-mount
  • Phase Hybrid AF improved but not at Sony's AI tracking level

Sony A7 IV

What works

  • 33MP sensor vs S5 IIX's 24.2MP — more stills resolution and crop flexibility
  • AI subject recognition AF for reliable documentary and event tracking
  • E-mount — world's largest mirrorless lens ecosystem

What doesn't

  • No internal ProRes — H.265 codec demands more in post
  • Sony's video-specific features trail the dedicated S5 IIX workflow
  • No unlimited recording — thermal limits at extended 4K/60p recording

Bottom line

Our pick: Sony A7 IV.
