The DL system was designed to accommodate larger diameter lenses, especially popular with full frame camera systems. The DL system uses the same sealing mechanism made popular on ikelite's compact dSLR and compact mirrorless housings.
This system utilizes a unique external o-ring seal which makes the port sealing o-ring highly visible and keeps water from dropping onto the camera body and sensor during lens changes.
The DL system has a rugged locking mechanism which is simple and secure without any complex gearing or parts that may break in a remote location.
The system is designed with positive orientation and virtually no movement when secured properly--perfect for use in the surf and at depths up to 200’(60m).
