Mid-range Focus Optimizer 1 (MFO-1)

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.  With the Nikon AF-S VR Micro-NIKKOR 105mm f/2.8G IF-ED, you can achieve up to 1.2X magnification at MFD, and with the Canon RF 100mm f/2.8, you'll get up to 1.6X magnification.
