The SMC-3

 

Nauticam is proud to introduce the SMC-3, the latest evolution in our line of water contact optics! Designed as a renewed version of the acclaimed SMC-1, the SMC-3 boasts a lightweight build—now only one-third the weight of its predecessor—without compromising on optical performance.

Key Features

• Ultra-Lightweight Design: Weighing in at just two-thirds of the SMC-1, the SMC-3 offers unparalleled portability for on-the-go use.

• Superior Optical Performance: Enjoy the same exceptional clarity and precision you’ve come to expect from the SMC series.

• Increased Working Distance: The redesigned lens allows for a greater working distance, meaning it s easier to use and provides enhanced versatility.

• Premium Materials: Crafted with advanced materials to enhance durability while minimizing weight.

• Cost-Effective: Slightly more affordable than the discontinued SMC-1, the SMC-3 delivers exceptional value.

• Uncompromised Optical Quality

  The Super Macro Converter 3 is constructed from lenses that 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.

  Stunning Magnification

  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 2.4X 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.

  Improved Sharpness and Contrast

  As the Super Macro Converter 3 is optimized explicitly for using together with a macro lens underwater, images captured exhibit exceptional sharpness compared with conventional magnification lenses. Thanks to the broadband multi-layer anti-reflection coating on each surface of the lenses, images also exhibit higher contrast.

  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 light transmission.

  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. This working distance is crucial when capturing behavior with skittish subjects.

  Resolution

  High resolution was a primary design goal of the SMC project. This has been achieved using computer aided optimization and high grade optical glasses with unique refractive and dispersion properties. Images taken with this new system exhibit very high resolution and quality. Results have exceeded expectations, and these images rival the quality of the macro lens in air.

  Smooth Bokeh

  The Converter retains the optical properties of the macro lens for the whole system underwater, resulting in a blurred (out of focus) background that has a pleasing smoothness and creamy look, without the normal purple and green fringing.

  Avoiding Diffraction

  Due to the overall superior optical performance of the SMC-3 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.
