The E-704 consists of two lens sleeves; up to 350 and 650 mm long and one hand sleeve to access the lens or to attach a lens support.

The E-704 is designed to be attached to KATA's E-702, when shooting with extra long zoom or Telephoto lenses. Full length closure along the bottom rim enables quick setup and seals the tripod connection while providing an option to access the lens controls at any given point. For sealed access, the hand sleeve can be connected wherever convenient. The PP hood can be adjusted to fit a variety of lens diameters.
