Introducing our newest Water Contact Optic, the Mid-range focus optimizer or MFO-1.  The MFO-1 is designed to elevate your macro shooting experience by eliminating any noticeable focus hunting while ensuring crisper, sharper and more vibrant images.   
Key Features:
Enhanced Image Quality: Say goodbye to the limitations of flat ports. The MFO-1 dramatically improves your image quality, providing more accurate color reproduction and increased clarity by minimizing lens aberration.  
No Focus Hunting: The converter seamlessly adjusts the focus range of your lens, eliminating noticeable focus hunting and allowing for smooth, precise focusing even in challenging conditions.
Focus Range Conversion: For the Nikon AF-S VR Micro-NIKKOR 105mm f/2.8G IF-ED, the MFO-1 converts the focus range to an impressive 12.5cm - 114cm, giving you more flexibility to capture subjects at varying distances with ease. 
Increased Magnification: For close-up enthusiasts, the MFO-1 converter slightly increases magnification, allowing for incredible detail at extremely close ranges.
