This WonderPana XL 186 Core Filter Holder from FotodioX is designed to specifically fit the Sony FE 12-24mm f/2.8 GM lens and a separately available WonderPana 8" Holder Bracket. Those items can be combined to allow the convenient use of two 2mm thick filters measuring 7.9" wide, or one 2mm thick filter measuring 7.9" wide with one FotodioX 186mm round filter behind it. A compatible 186mm inner-pinch lens cap for 186mm FotodioX round filters is also provided.

The included WonderPana FreeArc XL Core Unit consists of a compression front filter ring. Use of the WonderPana 8" Holder Bracket is easily accomplished by attaching its two assembly pieces to opposite sides of the FreeArc XL Core Unit using six of that holder bracket's eight included brass screws. Pre-tapped threaded inserts along the edge of the Core Unit accommodate those screws and ensure that the two assembly pieces are positioned parallel to each other and can hold a 7.9" wide filter between them. The combined holder bracket and front filter ring can then be attached to a Sony FE 12-24mm f/2.8 GM lens by tightening the Core Unit's locking mechanism. After being fitted onto the lens, the bearing design of this WonderPana FreeArc XL Core Unit allows a WonderPana 8" Holder Bracket to rotate 360°, permitting the use of graduated neutral density and other filters enhanced by varied positioning.

The FotodioX WonderPana 8" Holder Bracket provides two pairs of filter slots, a configuration that accommodates two compatible rectangular filters. For each rectangular filter 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 and hold it in place while permitting 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.

This FotodioX WonderPana FreeArc XL Core Unit includes front filter threads that allow a FotodioX 186mm round filter to be used along with a WonderPana 8" Holder Bracket. If a 186mm round filter is used on the attached WonderPana FreeArc XL Core Unit, the rectangular filter slot closest to the rear of the holder bracket becomes unavailable.

The FotodioX 186mm Center-Pinch Snap-On Lens Cap is a 186mm front lens cap with a squeeze, spring, and snap-on mechanism. It is easy to install as well as remove and can attach to a WonderPana FreeArc XL filter holder system to protect the front element of a lens any one of those systems is mounted on. Additionally, with the exception of the FotodioX Ultra Slim filters, this lens cap can protect a FotodioX 186mm filter mounted on a FotodioX WonderPana FreeArc XL filter holder system. Lens caps protect the lens or filter from scratches, fingerprints, and the elements when the lens or filter is not in use.
