Capture images of coral reefs, parrot fish, and shipwrecks at depths as great as 200' with this DLM 6" Dome Port from Ikelite. It fits onto the brand's underwater camera housings with DLM mounts, and accommodates many wide-angle mirrorless lenses with the appropriate zoom gears. Compatible models include those from Canon, Olympus, Panasonic, Sony, Tokina, and Sigma. For a complete list of lenses, please see the DLM/A, DLM/B, and DLM/C port charts.Built for durability, the port features a front element crafted from lightweight acrylic and a body made from Delrin acetyl resin, both of which are corrosion-resistant. The port's 6.0" dome magnifies images to a lesser degree than a flat port does, and corrects for the underwater size distortion that makes everything appear 25% larger and closer--thus helping to restore a wide angle of view. This broad coverage enables you to get close to your subject to increase clarity and detail, while still fitting everything in the frame                                               Compatible Lenses     Many wide-angle mirrorless zoom lenses from Canon, Olympus, Panasonic, Sony, Tokina, and Sigma.
