55 mm Adapter Ring for 4x4 Filter Holder
The ProOPTIC 55 mm adapter ring connects lenses with 55 mm front threads to the 4x4 or 100 mm square filter holder system. Precision threading and aviation-grade CNC aluminium ensure a secure, repeatable fit. A matte black frosted finish reduces internal reflections. It is built for photographers and videographers using square filters on 55 mm threaded lenses.
Check lens thread size before ordering
Verify that the lens front thread measures exactly 55 mm, as this ring only fits that diameter. The adapter converts the lens thread to the holder's 86 mm mounting ring. Ensure the 4x4 filter holder you own uses the 86 mm ring system. No other thread sizes or holder standards are compatible with this specific adapter.
Replaces mismatched step rings
This adapter replaces generic step-up rings that can vignette or loosen when a square filter holder is attached. The direct 55 mm to 86 mm connection maintains alignment and reduces light leaks. The upgrade is worth it when you regularly use 4x4 square filters on 55 mm lenses and need a rigid, anti-reflective interface.
