Ikelite acrylic domes are injection molded specifically for underwater photography, and represent the finest optics in the industry. Domes are recommended for lenses 28mm and wider to preserve the full angle of coverage.
Zoom is operable using the Large Diameter Zoom Set, included with all Ikelite DSLR housings. A +2 close-up lens is not required, but may be added to improve edge sharpness. Auto-focus only.
