WonderPana filter system for Nikon AF-S FX 12-24mm f/2.8mm ED Lens

The Fotodiox WonderPana filter system is designed specifically for ultra-wide-angle lens with built-in hoods and protruding bulbous elements — such as the Nikon AF-S NIKKOR 14-24mm f/2.8G ED.
Because these lenses lack traditional front filter threads, the WonderPana system uses a custom collar and core setup to mount massive circular and rectangular filters without severe mechanical vignetting and also no light leakage that typically other filter system fails to achive.

System Components:
• Rear Lens Collar & Core: A two-piece or multi-piece adapter that slides over the rear/body of the lens and locks onto the front tulip hood section.
• 145mm Round Filters: Accommodates oversized 145mm screw-in filters including ultra-slim multi-coated neutral density filters
• FreeArc 360° Rotation: The FreeArc core allows the holder to rotate 360 degrees independently, which is essential for positioning circular polarizers or graduated filters.
• Rectangular Filter Brackets: Can be paired with an optional 6.6-inch wide holder bracket to stack square or rectangular graduated ND filters alongside round filters.

Key Considerations:
• Polarizer Behavior on Ultra-Wide Lenses: As noted by landscape photographers on forums like DPReview
• Using a CPL at ultra-wide focal lengths (like 14mm) can cause uneven polarization across wide skies or blue gradients
