Selling my Fantasea UCL‑05LF close‑up lens. This is a +6 diopter wet lens that adds noticeable magnification for macro subjects while maintaining comfortable working distance. Great for nudibranchs, small fish, and detail work without committing to full supermacro.

Optics are clean with no scratches, haze, or coating marks. Threads are smooth and corrosion‑free. Used only lightly and always rinsed and dried properly.

Includes front and rear caps.

New retail is $180 — asking $120.

Located in San Antonio, TX; shipping included for U.S. buyers. Local pickup available.

Price drop: $100.00.

Moving up to a Nauticam CMC-2 for my OM-1 kit, so this great starter lens needs a new home.

Technical Highlight: This is the high-end 4-element achromatic version, not a cheap single-glass diopter. It provides zero purple fringing and tack-sharp corners—perfect for capturing tiny subjects in high-contrast tropical water.
