The Nauticam SMC-2 (Super Macro Converter 2), SKU 81202, is an ultra-high-magnification water-contact wet lens engineered for serious underwater macro and super-macro photographers. Key Concept & Purpose The SMC-2 delivers an incredible 4x magnification factor when paired with a full-frame camera and a standard macro lens (such as a 100mm or 105mm primary lens). It builds on the immense success of the original SMC-1, roughly doubling its magnification power to achieve extreme super-macro framing while maintaining pristine optical clarity. Specifications SKU: 81202 Primary Function: Ultra-high magnification (4x) wet macro conversion lens for capturing microscopic subjects (e.g., tiny pygmy seahorses, shrimp eyes, and tiny crustacean details). Magnification: Up to 4:1 reproduction ratio when combined with standard full-frame 100mm/105mm macro lenses. Optical Construction: Precision-crafted from specially formulated low-dispersion optical-grade glass with broadband anti-reflective coatings on all surfaces. Nitrogen-purged during assembly to prevent internal fogging. Mount Thread: M67 (fully compatible with 67mm threaded ports or the Nauticam Bayonet Mount Adaptor SKU 83214). Dimensions: Outer Diameter 70 mm × Length 54 mm. Weight: 540 g (on land). Depth Rating: 100 meters (330 ft). Key Benefits Stunning Detail & Resolution: Unlike traditional dry diopters sealed in air housings, the SMC-2 is a true water-contact optic designed using computer-aided modeling to factor in the physics of water. It delivers edge-to-edge sharpness, high contrast, and virtually zero chromatic aberration or color fringing. Autofocus Friendly: Despite its massive magnifying power, the high contrast and brightness optimization allow modern mirrorless and DSLR autofocus systems to lock on reliably. Smooth Bokeh: Retains the natural, creamy out-of-focus background blur of your primary macro lens without introducing ugly artifacts. Avoids Diffraction: Because of its superior optical sharpness, it allows you to shoot at slightly wider apertures than typical low-quality diopters, helping you bypass the diffraction limits of high-resolution camera sensors.
