This WonderPana FreeArc Core Unit Kit from FotodioX includes a WonderPana FreeArc Core Unit designed to specifically fit the Panasonic Lumix G Vario 7-14mm f/4.0 ASPH. lens, as well as a 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.
The included WonderPana FreeArc Core Unit consists of two components, a front filter holder and a rear lens collar. Placement of this FreeArc Core Unit onto a Panasonic Lumix G Vario 7-14mm f/4.0 ASPH. 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.
To use the WonderPana 6.6" Holder Bracket with the FreeArc Core Unit for a Panasonic Lumix G Vario 7-14mm f/4.0 ASPH. lens, pre-tapped threaded inserts along the edge of the front filter holder accommodate the six included brass short-screws for correct positioning of the WonderPana 6.6" Holder Bracket's two assembly pieces so that they are placed parallel to each other and can hold a 6.6"-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 Panasonic Lumix G Vario 7-14mm f/4.0 ASPH. lens, the front filter holder with the attached holder bracket can be screwed onto the installed rear lens collar.
After being fitted onto a Panasonic Lumix G Vario 7-14mm f/4.0 ASPH. 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.
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.
This FotodioX WonderPana FreeArc Core Unit includes front filter threads, which allow a FotodioX 145mm round filter to be used along with the holder bracket. If a 145mm round filter is used on the attached WonderPana FreeArc Core Unit, the rectangular filter slot closest to the rear of the holder bracket becomes unavailable. The WonderPana 6.6" Holder Bracket features a durable and lightweight aluminum-alloy construction that has a corrosion-resistant, black anodized finish.
The FotodioX 145mm Center-Pinch Snap-On Lens Cap for Select WonderPana Systems and Filters is a 145mm 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 145, FreeArc, or Absolute 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-slim FotodioX WonderPana 145 filter that is mounted on a FotodioX WonderPana 145, FreeArc, or Absolute filter holder system and has no other filters 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.
