GearNews - Nauticam CMC Compact Macro Converter
Nauticam says it has used computer software to model a lens that complements camera, port, air and water - an entire system. This accounts for the critical air-water interfaces in a conversion lens it says is designed to achieve the best image quality possible. The CMC has been designed primarily for use with compact and mirrorless camera systems but is also compatible with a number of DSLR lens options. It is priced at £245.
