This FotodioX WonderPana 145 Core Unit Kit Rokinon Samyang AF 14mmfrom FotodioX WonderPana 145 Core Unit Kit Rokinon Samyang AF 14mmincludes a WonderPana 145 Core Unit designed to specifically fit the Rokinon/Samyang AF 14mm f/2.8 RF/FE, 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. A 145mm inner-pinch lens cap for 145mm FotodioX round filters is also provided.

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 a Rokinon/Samyang AF 14mm f/2.8 RF/FE 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.

After being fitted onto a Rokinon/Samyang AF 14mm f/2.8 RF/FE, 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 is 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 features an aluminum alloy construction and 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.
