Key Features
Optimized for Macro Photography
The 3.2-inch flat port is engineered for longer macro lenses that require additional clearance inside the housing. When paired with the appropriate DLM extension ring, it provides the correct optical spacing for outstanding close-focus performance and sharp underwater images.
Built for the DLM System
This port is compatible with Ikelite's DLM (Dry Lock Micro) port system used on many mirrorless and compact DSLR housings. It is not compatible with Ikelite DL or FL port systems.
Expand with Wet Macro Lenses
A standard 67mm threaded front allows you to attach wet close-up lenses and diopters directly to the port, making it easy to increase magnification during a dive without opening the housing.
Premium Construction
The housing is machined from corrosion-resistant anodized aluminum with an optical glass front element for maximum durability and image quality, even after years of diving in saltwater environments.
