Nauticam CMC-2 2.8x Compact Macro Converter (67 mm)

The CMC-2 is an extremely powerful super macro accessory lens optimized for use with both fixed lens compact and mirrorless interchangeable lens cameras.

Smaller, Lighter, Stronger
CMC-2 is a new macro lens designed to stand alongside the previous CMC-1, offering a less powerful lens choice for “larger” macro subjects that is noticeably easier to use.

CMC-2 is a follow-up designed to give photographers using compact systems more magnification choices without sacrificing quality. New underwater photographers, or new system owners, will appreciate an easier to use lens with more accurate autofocus performance than stronger lenses can offer. More experienced users will find that CMC-2 is an ideal companion to CMC-1, allowing the perfect lens to be selected based on the subject size.

The CMC-2 ships with the common 67mm threaded lens mount. The lens has a protruding rear element, designed to place the accessory optic as close to the camera lens port as is possible, providing the best overall image quality when used with flip lens adapters. A flush mount adapter ring is used when attaching CMC-2 directly to an underwater housing, and is included with the lens.

Improved Sharpness
During pre-production testing we noticed a stunning increase in overall image sharpness when comparing shots taken with CMC-2 to those behind a flat port (with no accessory lens at all). It became clear that with both compact cameras at full telephoto and mirrorless interchangeable lens systems the conversion lens markedly improved overall sharpness. This is counter intuitive, as conventional wisdom implies that any conversion lens reduces image quality. In this case, the flat port degrades overall sharpness, and the optical correction offered by the CMC-2 restores it.

Simply put – an image taken underwater with CMC-2 is sharper than the same image taken with no accessory lens mounted. These are true water-contact corrective optics!

Uncompromised Optical Quality
The Compact Macro Converter is constructed from lenses precision crafted of specially formulated low dispersion optical grade glass, ground to the most demanding standards. This means greater sharpness and contrast on every shot and extraordinary resolution rivaling a macro lens used in air. Broadband anti-refective coatings effectively reduce common optical issues such as chromatic aberrations, coma, spherical aberration, and field deformation associated with underwater macro photography using traditional magnifying lenses.

Stunning Magnification
The CMC is compatible with a variety of camera systems, but the most impressive increase in magnification comes when paired with the Olympus M.ZUIKO DIGITAL ED 60mm f/2.8 Macro Lens for Micro Four Thirds Systems. This combination achieves a 2:1 reproduction ratio. This translates into an image 8.5mm X 6.3MM, and one of the most powerful macro imaging systems available in the market today.
