WonderPana Overview

Challenging shooting scenarios often call for adding a lens filter to save the shot. However when you're shooting with an Wide Angle or Ultra Wide Angle lens, the bulbous front lens element and lack of threads make it impossible to add filters - until WonderPana. The WonderPana is a complete filter system designed expressly for filtering UWA and WA lenses without vignetting.

With a selection of 20+ different custom lens mounts, plus over 25 different filters, there is a perfect creative combination for any photographer or videographer. We offer 145mm round circular polarizer filters, neutral density ND4-1000, and a selection of 6.6" soft and hard edged rotating square gradient filters.



WonderPana FreeArc Core Option

• If you want to use rectangular graduated filters or mix both round and graduated filters and rotate them to set the horizon line wherever you want, this is for you!

Comprising the dedicated filter holder and a optional bracket for attaching 6.6"-wide rectangular filters, this WonderPana FreeArc Core Filter Holder and 6.6" add-on bracket from Fotodiox enables attaching 145mm threaded filters and caps to the lens, which itself lacks filter threads, the bracket can be added for working with 6.6"-wide square and rectangular filters. Once assembled, the entire system rotates a full 360° for flexible placement of the filter in use.

The optional Fotodiox WonderPana 6.6" Holder Bracket is a two-piece assembly designed to be used in combination with a Fotodiox WonderPana FreeArc Core Unit. When attached it then allows for the convenient use of two 2.5 to 4.0mm-thick filters measuring 6.6in wide, or one 6.6in wide filter along with one 145mm round filter behind it. The WonderPana 6.6" Holder Bracket features a lightweight, aluminum-alloy construction that has a corrosion-resistant, black anodized finish for durability. A rigid pouch is included for storage and transport.

Chloe ★★★★★

The locking ring on this filter holder clicks into place with a satisfyingly solid feel, and the 145mm filter slot is exactly what I needed for my Sigma 20mm Art lens. It also works perfectly as a lens hood, keeping stray light off the glass during long exposures.

Isabella ★★★★★

I was skeptical about carrying a filter system this big, but the way it doubles as a lens hood makes it feel like a two-for-one deal. The 145mm filter mounting is rock solid with no vignetting on my Sigma 20mm, even when I stack a polarizer and ND. Protection and function in one piece, and that’s ra

Julian ★★★★★

Finally, a filter solution that doesn't add noticeable weight to my already oversized Sigma setup—the built-in hood alone is worth it for protecting that bulbous front element on hikes.
