WonderPana Filter Holder for Sigma 14mm f/2.8 EX HSM RF Aspherical Ultra Wide Angle Lens (Full Frame 35mm) - Ultra Wide Angle Lens Filter Adapter

Product Highlights:

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 145 Core Option

• Great option for attaching a single round filter to your ultra wide angle lens!

The WonderPana 145 Core Filter Holder is a dedicated holder for attaching 145mm threaded filters and caps to this ultra wide-angle lens that lacks front threads. The holder is also compatible with the optional WonderPana 6.6" Holder Bracket for attaching 6.6"-wide rectangular filters. The 145 Core Filter Holder has a rigid all-metal construction and attaches directly to the lens barrel for a secure fit that does not affect lens performance. Additionally, the holder extends beyond the lens's integrated hood to provide additional protection against bumps and impacts. Included with the holder is a 145mm lens cap and soft pouches for storage.

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.

WonderPana Absolute Core Option

• Designed for if you already have either the Lee SW-150 system or the Cokin X-Pro system and want to attach them to other lenses.

The WonderPana Absolute kit contains a 150mm filter holder adapter ring for the Lee SW-150 filter system (not included), a 130mm WonderPana Absolute filter holder adapter ring and a filter holder for both the Cokin X-Pro and Fotodiox Pro 130mm filter systems (not included), a 145mm WonderPana Absolute filter adapter ring for 145mm Fotodiox round filters, a lens-dedicated retention ring, plus a 145mm inner-pinch lens cap.

The adapter ring for a Lee SW-150 filter holder, as well as the adapter ring for the Cokin X-Pro and Fotodiox Pro 130mm filter holders, securely connect to their compatible filter holders. They each allow for a filter holder's free rotation around the lens to complement the use of LEE SW-150, Cokin X-Pro, or Fotodiox Pro 130mm graduated neutral density or other filters that are enhanced by varied positioning. Compatible filters can be screwed into the filter adapter ring for 145mm Fotodiox round filters. Each adapter ring is designed to help avoid any vignetting. The retention ring and adapter rings within this kit are constructed using aluminum-alloy for durability while remaining lightweight.
