FotodioX

This WonderPana FreeArc Core Unit from FotodioX is designed to specifically fit the Tokina AF 10-17mm f/3.5-4.5 AT-X 107 AF DX NH fisheye lens as well as a separately available WonderPana 6.6" Holder Bracket. Those items can be combined to 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. Compatible 145mm solid neutral density 1.2 and 1.5 filters, as well as a 145mm inner-pinch lens cap for 145mm FotodioX round filters, are also provided. The included WonderPana FreeArc Core Unit consists of a compression front filter ring. Use of the WonderPana 6.6" Holder Bracket is easily accomplished by separately attaching its two assembly pieces to opposite sides of this WonderPana Core Unit using the six included brass short screws. Pretapped threaded inserts along the edge of this Core Unit accommodate those screws and ensure correct positioning of the two assembly pieces so that they are placed parallel to each other and can hold a 6.6" wide filter between them. The combined WonderPana Core Unit and WonderPana 6.6" Holder Bracket can then be attached to a Tokina AF 10-17mm f/3.5-4.5 AT-X 107 AF DX NH fisheye lens by tightening the Core Unit's locking mechanism. After being fitted onto a Tokina AF 10-17mm f/3.5-4.5 AT-X 107 AF DX NH fisheye lens, the bearing design of this WonderPana FreeArc Core Unit 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. A 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. Pretapped 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. This FotodioX WonderPana FreeArc Core Unit 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.None 1.2 optical density filter darkens the image, allowing you to photograph with a longer shutter speed or wider aperture than normally required.None Providing a 4-stop exposure reduction, this filter allows you to control depth of field and convey movement more easily.None Filter does not affect coloration of the image and is ideal for use with other filters.None Includes multiple layers of anti-reflection coating to prevent internal ghosting and reflections.None Constructed optical glass for clarity and color fidelity.None 145mm front filter threads allow for use with other filters.None Durable, lightweight aluminum-alloy filter ring with one brass side knob allows the filter to be easily screwed on or off.None Filter pouch included for storage and transport.
