Alexa to Pro-style dovetail plate for DBox mounting with side-to-side adjustment

12 years old. Gear and prices may have changed since.

What the thread found

  • A dovetail adapter plate designed for Alexa cameras includes integrated Pro-style dovetail and mounts directly to DBox without requiring a separate intermediate plate.
  • The plate provides approximately 2 inches of lateral adjustment while mounted to the DBox.
  • Two versions are available: a longer version suited for zoom lenses and a shorter version for prime lenses.
  • Lateral adjustment capability allows operators to keep the DBox centered, which provides margin for accessories or configuration changes without exhausting side-to-side adjustment range.
  • The plate includes threaded holes for alternative mounting applications beyond DBox use.
  • A competing all-in-one Alexa plate from Panavision exists that also offers side-to-side adjustment when mounted on DBox, though with an undersized dovetail and reportedly more difficult tie-down.
  • Available dimensions are 10.25 inches for the short version and 12.25 inches for the long version.

Depends on

  • The discussion does not specify plate thickness.
  • Compatibility with Alexa Studio cameras (which lack rod mounts) is mentioned as a question but not answered in the thread.
  • The exact amount of side-to-side adjustment capability and whether it accommodates 15mm rods is unclear from the discussion.
  • User preferences regarding DBox centering are anecdotal rather than based on systematic testing.
