Nauticam SMC-1 2.3x Super Macro Converter (67 mm)
Nauticam SMC-1 close up lens is specifically designed and made for underwater use and gives a magnification factor of 2.3x. (+15).
Breakthrough Lens Design
Prior to the Super Macro Converter, achieving “super macro” underwater meant using tools that were
designed for in air use. These tools simply do not take into account the physics of shooting in water. The
SMC takes a radically different approach: treat the system - camera, lens, port, air, and water – as a whole,
and account for the air-water interfaces in a conversion lens design to achieve the best image quality
possible. The improvement is stunning, measurable and a new standard in underwater macro imaging has
Uncompromised Optical Quality
The Super Macro Converter is constructed from lenses are precision crafted of specially formulated low
dispersion optical grade glass, ground to the most demanding standards. These exceptional measures,
enhanced by 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. These optics are assembled in a rugged hard anodized
aluminum housing, and nitrogen purged during assembly to eliminate fogging.
When combined with a full frame camera and a 100mm or 105mm macro lens, the device converts the
optical system to provide a maximum of 2.3X magnification factor. In other words, a subject area of 15.6mm
X 10.4mm will fill the whole frame of a 36mm X 24mm sensor.
Superb Light Transmission
All the lens elements installed inside the SMC are optically optimized to appropriate diameters so as to
provide maximum light transmission. The SMC doesn’t suffer from vignette issues under even the most
extreme conditions. The broad band multi-layer anti-reflection coating on all surfaces also greatly improves
Optimized for Autofocus
By utilizing a specially developed algorithm in the optimization process, the SMC renders superior image
quality over the full focusing range of the camera lens (which becomes ~50 to ~100 mm in front of the SMC).
Also benefitting from the high brightness and contrast of the image, the autofocus system of the camera
usually works acceptably well within this range.
Ample Working Distance
Even at the maximum 2.3X magnification, there is still more than 50mm of working distance between the
front element and the subject with 100/105mm macro lenses.
Also Compatible with Nikon AF-S 60mm Macro
While designed with compact cameras in mind, compatibility with larger formats has proven to be possible
in some cases. Nikon AF-S 60mm Macro (not compatible with the earlier SMC-1) provides 1.5 : 1
Reproduction Ratio when with combined CMC-1. Image quality is excellent, even when used with full frame
systems. This combination is extremely versatile, covering fish portraits, 1:1 macro, and now 1.5:1 super macro on the same dive!
Due to the overall superior optical performance of the SMC it is possible to shoot larger apertures with
excellent image quality. This avoids reaching the diffraction limit of high resolution sensors, and allows
selective focus effects with narrow depth of field in super macro images.
