This WonderPana FreeArc XL Core Unit Kit from FotodioX includes a WonderPana FreeArc XL Core Unit designed to specifically fit the Sigma 12-24mm f/4 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. A compatible 186mm slim circular polarizer filter and a 186mm inner-pinch lens cap for 186mm FotodioX round filters are also provided.

The included WonderPana FreeArc XL Core Unit consists of two components, a front filter holder and a rear lens collar. Placement of this FreeArc XL Core Unit onto a Sigma 12-24mm f/4 DG HSM Art lens is easily accomplished by sliding the rear lens collar over the rear of the lens until it has achieved a secure fit. Afterwards, the front filter holder can be screwed onto the front of the installed rear lens collar.

So that a WonderPana 8.0" Holder Bracket can be used with this FreeArc XL Core Unit for a Sigma 12-24mm f/4 DG HSM Art lens, pre-tapped threaded inserts along the edge of the front filter holder accommodate six of that holder bracket's eight included brass short-screws. Those screws ensure that a WonderPana 8.0" Holder Bracket's two assembly pieces are positioned parallel to each other and can hold a 7.9" wide filter between them. Once the holder bracket and the front filter holder are combined, and the separate collar has been slid over the rear of a Sigma 12-24mm f/4 DG HSM Art lens, the front filter holder with the attached holder bracket can be screwed onto the installed rear lens collar.

After being fitted onto a Sigma 12-24mm f/4 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 Center-Pinch Snap-On Lens Cap for Select WonderPana Systems and Filters 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 is mounted on. Additionally, with the exception of the FotodioX Ultra Slim filters, this lens cap can be used to protect a FotodioX 186mm filter that is mounted on a FotodioX WonderPana FreeArc XL filter holder system.

Lens caps protect your lens or filter from scratches, fingerprints, and the elements when the lens or filter is not in use.

FotodioX 186mm Slim Circular Polarizer Filter

The FotodioX 186mm Slim Circular Polarizer Filter is compatible with FotodioX WonderPana FreeArc XL holder systems. It helps to reduce reflections as well as glare by filtering out light that has become polarized due to reflection from a non-metallic surface. The light from the sun naturally becomes partially polarized due to reflecting off electrons in air molecules, causing the light to scatter into what appears as haze. A polarizing filter arranges, and filters, this directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of this light. This results in a noticeable reduction of glare and reflections from non-metallic surfaces and an increase in the saturation of skies and foliage.

A circular polarizer only differs from a linear polarizer in that it contains a quarter wave plane in addition to the linear polarizing filter. The addition of this quarter wave plane is to circularly polarize the linearly polarized light for the use of auto focus and exposure functions. Due to how the light is broken down and filtered with a linear polarizer, auto focus and exposure accuracy become skewed during use. When the light becomes circularly polarized, it permits the use of these functions.

The FotodioX 186mm Slim Circular Polarizer Filter is constructed from optical glass for clarity as well as color fidelity and features lightweight, slim, aluminum-alloy filter rings. A rear filter ring connects to a compatible filter holder while the front filter ring allows the filter glass to be easily rotated. This provides the ability to achieve the desired degree of polarization.

A separately-available FotodioX 186mm Center-Pinch Snap-On Lens Cap can be used to protect the front of a FotodioX 186mm Slim Circular Polarizer Filter that is placed in front of a lens.
