This WonderPana 145 Core Unit Kit from FotodioX includes a WonderPana 145 Core Unit designed to specifically fit the Olympus 7-14mm f/4.0 Zuiko ED Zoom 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 are also provided, plus a 145mm inner-pinch lens cap for 145mm FotodioX round filters.
The included WonderPana 145 Core Unit consists of two components, a front filter holder and a rear lens collar. Placement of this 145 Core Unit onto an Olympus 7-14mm f/4.0 Zuiko ED Zoom 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 6.6" Holder Bracket can be used with this 145 Core Unit for an Olympus 7-14mm f/4.0 Zuiko ED Zoom lens, pre-tapped threaded inserts along the edge of the front filter holder accommodate that holder bracket's six included brass short-screws. These screws ensure that a WonderPana 6.6" Holder Bracket's two assembly pieces are positioned parallel to each other and can hold a 6.6"-wide filter between them. Once that holder bracket and the front filter holder are combined, and the separate collar has been slid over the rear of an Olympus 7-14mm f/4.0 Zuiko ED Zoom lens, the front filter holder with the attached holder bracket can be screwed onto the installed rear lens collar.
After being fitted onto an Olympus 7-14mm f/4.0 Zuiko ED Zoom lens, the eight pre-tapped threaded inserts all around the edge of the WonderPana 145 Core Unit allow a WonderPana 6.6" Holder Bracket to be installed in 45° increments so that rectangular filters placed within it can be angled to the best approximate position relative to the subject in front of the camera. This helps to benefit 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 brass long-screws that are also included with the holder bracket. 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 145 Core Unit includes front filter threads, which allow a FotodioX 145mm round filter to be used along with a WonderPana 6.6" Holder Bracket. If a 145mm round filter is used on the attached WonderPana 145 Core Unit, the rectangular filter slot closest to the rear of the holder bracket becomes unavailable.
The FotodioX 145mm Solid Neutral Density 1.2 Filter is an ND filter with a 16x filter factor that provides a 4-stop exposure reduction, while the FotodioX 145mm Solid Neutral Density 1.5 Filter is an ND filter with a 32x filter factor that provides a 5-stop exposure reduction. Their respective 1.2 and 1.5 densities create 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.
To prevent internal ghosting and reflections, these filters include multiple layers of anti-reflection coating. These coatings also offer greater protection to the filters' substrates and help them to stay clean for longer than with uncoated filters. These FotodioX 145mm Solid Neutral Density 1.2 and 1.5 Filters are constructed from optical glass for clarity as well as color fidelity and both feature an aluminum-alloy filter ring for durability while remaining lightweight.
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.
