The FotodioX WonderPana FreeArc XL Kit for Sigma 14mm Art Lensis a two-piece assembly designed to be used in combination with a FotodioX WonderPana FreeArc XL Core Unit or a WonderPana XL Aluminum Step-Up Ring. Attaching the WonderPana 8.0" Holder Bracket to a WonderPana FreeArc XL Core Unit or a WonderPana XL Aluminum Step-Up Ring can allow for the convenient use of two 2.0mm-thick filters measuring 7.9" wide, or one 2.0mm-thick filter measuring 7.9" wide along with one FotodioX 186mm round filter behind it.

Use of this holder bracket is easily accomplished by separately attaching its two assembly pieces to opposite sides of a WonderPana FreeArc XL Core Unit or a WonderPana XL Aluminum Step-Up Ring using six of the eight included brass short-screws. Pre-tapped threaded inserts along the edge of a WonderPana XL Aluminum Step-Up Ring accommodate those screws and ensure correct positioning of the two assembly pieces so that they are positioned parallel to each other and can hold a 7.9"-wide filter between them. The combined WonderPana XL Aluminum Step-Up Ring, and WonderPana 8.0" Holder Bracket can then be attached to a compatible lens.

For WonderPana FreeArc XL Core Units that consist of a rear lens collar and a front filter holder, pre-tapped threaded inserts along the edge of the front filter holder accommodate six of the eight brass short-screws for correct positioning of the WonderPana 8.0" Holder Bracket's two assembly pieces. Once the holder bracket and a front filter holder are combined, and the separate collar has been slid over the rear of a compatible lens until it has achieved a secure fit, the front filter holder with the attached holder bracket can be screwed onto the front of the installed rear lens collar.

After being fitted onto a compatible lens, the bearing design of the WonderPana FreeArc XL Core Unit allows a WonderPana 8.0" Holder Bracket to be rotated 360°. This permits the use of graduated neutral density and other filters that are enhanced by varied positioning.

The FotodioX WonderPana 8.0" Holder Bracket provides two pairs of filter slots, a configuration that accommodates two compatible rectangular filters. For each rectangular filter that is placed within one of the holder bracket's slots, its position is secured by integrated guides within each slot. These guides apply pressure along both sides of a filter that is sufficient to hold it in place, but permits movement of that filter. This can complement the use of graduated filters whose effect can be adjusted to better suit changing lighting conditions or creative demands by sliding them up or down within a filter slot.

The WonderPana 8.0" 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.
