Saga has announced a new BK-7 optical glass 4” (100mm) dome port for use with Ikelite DL port system housings. The dome has an external coating that maximizes light transmission, and an internal anti-reflective one. The port is optimized for use with fisheyes lenses, specifically, the Tokina 10-17mm and both Nikon and Canon 8-15mm lenses. The shade and back pane is constructed of anodized aluminum, and the shade is removable to allow for full circle images.
The Saga 4” dome port is shipping now, priced at €695 (incl. VAT).
