The FotodioX WonderPana 8.0" Holder Bracket is 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.This FotodioX Slim ND Filter features 18mm front filter threads and has a 16x filter factor that provides a 4-stop exposure reduction and is compatible with FotodioX WonderPana FreeArc XL filter holder systems. Its 1.2 optical density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily. Neutral density filters do not affect the coloration of the image and are ideal for pairing with other filters.





This filter is constructed from optical glass for clarity as well as color fidelity and features a lightweight, slim, aluminum-alloy filter ring to minimize the potential for vignetting. A separately-available FotodioX 186mm Center-Pinch Snap-On Lens Cap can be used to protect the front of a FotodioX 186mm Slim ND 1.2 Filter that is placed in front of a lens.This 3-stop, 7.9 x 10.2" FotodioX Hard-Edge Graduated ND Filter is designed for use with the WonderPana 80 and FreeArc XL filter holder systems. It helps to darken specific areas of an image, such as bright skies, while allowing for a normal, unaffected exposure in the other regions of the image, making a useful filter for photographing landscapes with sky and and horizon. The filter is densest at the edge and tapers to clear by the middle, with a hard-edged line of transition between the dense and clear areas. A neutral density filter with a hard-edged line of transition is particularly useful for images that feature horizons, or any hard transition between the sky and land. Neutral density filters do not affect the coloration of the image and this filter provides up to a 3-stop reduction in light from entering a lens. This filter is made of durable, CR39 optical resin and measures 4mm thick. A carrying pouch is also included with the filter.The 186mm Center-Pinch Snap-On Lens Cap for Select WonderPana Systems and Filters from FotodioX 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 in order to protect the front element of a lens that any one of those systems are mounted on. Additionally, this lens cap can be used to protect a non-ultra slim FotodioX WonderPana 186mm filter mounted on a FotodioX WonderPana FreeArc XL filter holder system, with no other filter placed in front of it.





Lens caps protect your lens or filter from scratches, fingerprints, and the elements when the lens or filter is not in use. It's always good to have a spare in your camera bag.
