Nauticam Super Macro Converter 3 SMC-3

Nauticam Super Macro Convertor 3 (SMC-3) 2.3x Magnification.

The redesigned Super Macro Converter 3 is more travel friendly at only a third of the weight of the original SMC-1 and smaller in size.  Despite this the SMC-3 offers the same level of magnification and optical performance as the SMC-1

The lens is equipped with a standard 67mm thread but we recommend using it with a flip diopter holder to easily install and remove as needed throughout your dive.  

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 2.3X 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.

IMPROVED SHARPNESS AND CONTRAST

As the Super Macro Converter 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 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.
