Images captured with the lens are exceptionally detailed and feature impressive overall sharpness. The combination of a super wide field of view (130 degrees) and zero minimal focus distance provide unlimited opportunities for image framing and creative compositions, including close focus wide angle and over-under (half/half) split images. Professionally engineered elements eliminate chromatic aberration. The AR (anti-reflection) coating on all glass elements assists in avoiding lens flare from the sun or artificial light sources.Durable ConstructionLens barrel is made from durable Aluminum alloy with black hard coating. The dome is covered with hard coating as well, protecting it from easily getting scratched or damaged. During development, the lens was thoroughly tested in extreme conditions (depth, temperature, salinity and radiation) to ensure resistance and durability on the long run.Rotatable WingsLens wings feature an improved design and can be rotated anytime underwater according to image composition without using any tools. Vertical and horizontal images can be easily captured without having the sun or strobes reflecting on the dome and interfering with crystal clear images.Universal CompatibilityThe lens features a 67mm thread mount, compatible with most housings available in the market today. Perfect to be used with compact, mirrorless or SLR housings. Two different adaptors are included with the lens, to ensure the best fit with all type of housings, sparing the need to solve ahead any compatibility issues or source additional adaptors separately.
