Marelux Mono Flip Holder: The Ultimate Solution for Underwater Macro Photography
Why the Mono Flip Holder is Essential
A mono flip holder is a vital tool for underwater macro photographers. It securely mounts a single wet lens—such as a +5, +10, or +15 diopter, or the newly introduced MV60 or MV24 wider-angle conversion lens. This setup gives you the ultimate versatility to engage high magnification instantly, or flip the wet lens completely away to shoot through your native flat port with zero restrictions.
The Flaws in Traditional Flip Holders
Standard single flip holders currently on the market suffer from two major design flaws:
Corrosion and Jamming: Most brands utilize land-based mechanical designs featuring exposed internal springs and ball bearings. When exposed to harsh saltwater, these components inevitably corrode. Over time, the mechanism jams, requires constant lubricant sprays, and eventually fails completely.
Weak Holding Power for Heavy Lenses: Traditional ball-and-spring mechanisms lack the tension needed to secure large, heavy wet lenses (such as the MV60 or MV24, which weigh between 600 to 1,000 grams). As a result, the lens can shake, loosen, or accidentally shift positions—especially on a fast-moving boat or if the housing accidentally bumps into a rock.
The Patented Marelux Innovation
Marelux is proud to introduce a patented design that permanently eliminates these industry-wide pain points with an elegant, corrosion-resistant, and rock-solid locking mechanism:
Push-Button Positive Locking System: Instead of relying on weak friction, ball bearings, or springs, the Marelux holder features an internal shaft lined with heavy-duty locking teeth. By completely eliminating ball-and-spring mechanisms, this innovative design is 100% immune to saltwater erosion and corrosion.
Effortless Operation: Simply press the button on the rotating joint to drop the shaft and disengage the locking teeth. You can then smoothly flip the arm into your active shooting position or standby position.
Unmatched Security: Releasing the button instantly snaps the shaft back into its locked position. This mechanical lock ensures that even the heavy wet lenses remain completely immobile—even during rough boat rides or accidental impacts against underwater structures.
Universal Compatibility
The Marelux Mono Flip Holder is engineered for maximum versatility across the industry. It is natively compatible with most major housing brands featuring a standard M67 (67mm) threaded port. To adapt it to non-Marelux housings, simply remove the two anti-rotation positioning screws used for Marelux macro ports, and thread it directly into place.
