FotodioX

This WonderPana FreeArc XL Core Unit from FotodioX is designed to specifically fit the Sigma 14-24mm f/2.8 DG HSM Art lens as well as a separately available WonderPana 8.0" Holder Bracket. Those items can be combined to 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. Compatible 186mm solid neutral density 1.2 and 1.5 filters, as well as a 186mm inner-pinch lens cap for 186mm FotodioX round filters, are also provided. The included WonderPana FreeArc Core Unit consists of a compression front filter ring. Use of the WonderPana 8.0" 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 short-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 Sigma 14-24mm f/2.8 DG HSM Art lens by tightening the Core Unit's locking mechanism. After being fitted onto a Sigma 14-24mm f/2.8 DG HSM Art lens, the bearing design of this 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. A 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. This FotodioX WonderPana FreeArc XL Core Unit includes front filter threads, which allow a FotodioX 186mm round filter to be used along with a WonderPana 8.0" 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 WonderPana 8.0" Holder Bracket features a durable and lightweight aluminum-alloy construction that has a corrosion-resistant, black anodized finish. The FotodioX 186mm Slim, Solid Neutral Density 1.2 Filter is an ND filter with 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 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. The FotodioX 186mm Slim, Solid Neutral Density 1.5 Filter is an ND filter with a 32x filter factor that provides a 5-stop exposure reduction and is also compatible with FotodioX WonderPana FreeArc XL filter holder systems. Its 1.5 density creates a darkening of the entire image as well, allowing you to photograph with a wider aperture or slower shutter speed than normally required. These 186mm solid neutral density filters are constructed from optical glass for clarity as well as color fidelity and feature lightweight, slim, aluminum-alloy filter rings to minimize the potential for vignetting.None Compatible with a Sigma 14-24mm f/2.8 DG HSM Art lensAccommodates a separately available WonderPana 8.0" Holder BracketWith a WonderPana 8.0" Ho
