FotodioX

This WonderPana 145 Core Unit from FotodioX includes a WonderPana 145 Core Unit designed to specifically fit the Sigma 12-24mm f/4.5-5.6 EX DG HSM 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. A compatible 145mm circular polarizer filter and a compatible 145mm solid neutral density 3.0 filter 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 a Sigma 12-24mm f/4.5-5.6 EX DG HSM 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 a Sigma 12-24mm f/4.5-5.6 EX DG HSM lens, pretapped 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 a Sigma 12-24mm f/4.5-5.6 EX DG HSM 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/4.5-5.6 EX DG HSM 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. 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 separately available 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.None Helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface.None Polarizing filters arrange, and filter, directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of the light.None Clears up haze in distant landscapes and provides more saturated, vivid colors.None Strongest effect when used at a 90 angle from the sun.None Circular polarizers are ideal for use with digital cameras and autofocus lenses where a linear polarizer will often disrupt auto exposure and focus features.None 1.25 to 8x filter factor reduces exposure by 0.3 to 3 stops.None Constructed from optical glass for clarity.None Lightweight, aluminum-alloy filter rings along with four brass side knobs allow the filter glass to be easily rotated. The desired effect can be easily achieved even if another filter is placed directly in front.None Filter pouch included for storage and transport.
