The FotodioX WonderPana 6.6" Holder Bracket is a two-piece assembly designed to be used in combination with a FotodioX WonderPana FreeArc Core Unit, a WonderPana 145 Core Unit, or a WonderPana FreeArc Aluminum Step-Up Ring. A WonderPana Core Unit or a WonderPana FreeArc Aluminum Step-Up Ring with the WonderPana 6.6" Holder Bracket attached can then allow for the convenient use of two 2.5 to 4.0mm-thick filters measuring 6.6" wide, or one 2.5 to 4.0mm-thick filter measuring 6.6" wide along with one FotodioX 145mm 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 Core Unit or a WonderPana FreeArc Aluminum Step-Up Ring using the six included brass short-screws. Pre-tapped threaded inserts along the edge of a WonderPana Core Unit or FreeArc 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 6.6"-wide filter between them. The combined WonderPana Core Unit, or WonderPana FreeArc Aluminum Step-Up Ring, and WonderPana 6.6" Holder Bracket can then be attached to a compatible lens.

For WonderPana 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 the six brass short-screws for correct positioning of the WonderPana 6.6" 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 Core Units and WonderPana FreeArc Aluminum Step-Up Rings allows a WonderPana 6.6" Holder Bracket to be rotated 360°. This permits the use of graduated neutral density and other filters that are enhanced by varied positioning. While a WonderPana 145 Core Unit does not include a 360° rotating mechanism, eight pre-tapped threaded inserts all around its edge allows the WonderPana 6.6" Holder Bracket to be installed in 45° increments so that rectangular filters placed within it can be angled to the best approximate position relative to the subject in front of the camera.

The FotodioX WonderPana 6.6" 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 can be secured using the included brass long-screws. Pre-tapped threaded inserts along the outside of the holder bracket allow the long-screws to each apply pressure to a spring-loaded retainer within each filter slot. When a pair of the long-screws are used, the level of grip upon a rectangular filter can be varied, which 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.

Each FotodioX WonderPana Core Unit or WonderPana FreeArc Aluminum Step-Up Ring includes front filter threads, which allow a FotodioX 145mm round filter to be used along with this filter holder. If a 145mm round filter is used on the attached WonderPana Core Unit or WonderPana FreeArc Aluminum Step-Up Ring, the rectangular filter slot closest to the rear of the holder bracket becomes unavailable. 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.

Related Questions and Answers

Q: 1. Does this Tray with both the filters take up only a single slot in the matte box?

A: No, The Tiffen Multi Rota Tray Variable Neutral Density Kit comes with one rotating Circular Polarizer Tray. When combined with one of the included 4x5.65" Circular Polarizer it becomes a Variable ND solution. However, the 4x5.65" Circular Polarizer would take up another space/slot in your Matte Box. A second 4x5.65" Circular Polarizer is included as a backup.

Q: 2. The description states, "if you're shooting a store window or inside a museum into a showcase, glass obstructions will no longer be a problem." Can anyone confirm that this eliminates or reduces reflection from glass? It cannot completely eliminate it or you would not capture your reflection in a mirror and I've not seen a filter that can to that. What does have you experienced? I am photographing painted and reflective surfaces of artifacts that cannot be physically modified to reduce glare.

A: Yes, polarizer will reduce or remove reflections from glass or paintings/photographs but it also depends on how the light is falling on the reflective surface and the angle that your are shooting at.
