FotodioX WNDPN145-CPL overview

  • 1Description

The FotodioX 145mm Circular Polarizer Filter is compatible with the FotodioX WonderPana 145, FreeArc, and Absolute filter 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 145mm Circular Polarizer Filter is constructed from optical glass for clarity as well as color fidelity and features lightweight, aluminum-alloy filter rings. A rear filter ring connects to a compatible filter holder while four brass knobs along the side of the front filter ring allow the filter glass to be easily rotated. This provides the ability to achieve the desired degree of polarization even if another filter is placed in front of the FotodioX 145mm Circular Polarizer Filter.

Helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface.
Polarizing filters arrange, and filter, directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of the light.
Clears up haze in distant landscapes and provides more saturated, vivid colors.
Strongest effect when used at a 90° angle from the sun.
Circular polarizers are ideal for use with digital cameras and autofocus lenses where a linear polarizer will often disrupt auto exposure and focus features.
1.25 to 8x filter factor reduces exposure by 0.3 to 3 stops.
Constructed from optical glass for clarity.
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.
Filter pouch included for storage and transport.

    FotodioX WNDPN145-CPL reviews

    145mm Circular Polarizer Filter is rated 4.4 out of 5 by 10.
    Rated 5 out of 5 by from Invaluable at eliminating reflections. Best used to eliminate reflections. Used shooting through water/window/glass panes (store fronts, various display cabinets, aquarium tank glass, Recreation Vehicle windscreens, airplane windows, etc..) and to remove reflections from polished stone surfaces (Marble, Granite, Tile, and China).

    Rated 5 out of 5 by from Works Perfectly 145mm is a large expanse of glass and I was somewhat concerned about the optical quality of such a large filter. My concerns were without foundation though as this filter creates tack sharp images with or without polarization. Well worth the money. Easy to attach to the FotodioX Kit for the 14-24mm Nikon lens... a welcome addition to my bag.

    Rated 3 out of 5 by from A bit less than expected Using this for landscape photography of course and it does work adequately, but not as 'strong' an effect as my 77mm Nikkor CPL. It is very 'stiff' while rotating the front element. It seems well built and the 145/66 system to attach it is robust and easy to install.

    Rated 5 out of 5 by from One for all !! With 145mm in size this great circular polarize filter cover the full frame with any lens without vigneting. Extra knobs for easy adjust with one finger !! Solid construction and quality and satisfation guaranty.

    Rated 5 out of 5 by from Great for Tamron 15-30mm Even though you might think you don't need a polarizer for an ultra wide-angle as it will distort the sky, it has been exceedingly for me for reflections on foliage and water as well as reflections of windows.

    Rated 5 out of 5 by from Good solution for 14-24 bulb lens This is a great solution for polarizing a 14-24 bulb lens. I have used it and it makes a great difference in folliage and water in landscapes. It is quite large but necessarily so to cover the lens.

    Rated 4 out of 5 by from Size does matter! A welcome addition to my Fotodiox WonderPana filter holder for my Nikon 14-28 F2.8 lens. Although not a small filter at 145mm, hanling it was easy and the results are worth the added bulk.

    Rated 5 out of 5 by from Big is bueatiful Using this for landscapes on the 14-24mm Nikkor. Fits straight on the Wonderpana system. Would buy the skinny version to leave an extra slot free on the FreeArc rather than this one.
