The FotodioX 53mm Circular Polarizer Filteris designed for use with the GoTough WonderPana Go Filter Adapter System for the GoPro HERO3 digital camera. It helps to reduce reflections and 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. This filter also includes a plastic storage box with cushion liner.

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.

Q: 1. Will this fit my tamron 15-30 when used with the wonderpana holder

A: Yes. This filter is 145mm and the Wonderpana WNDPN145-ESNTLCP-TMR1530 adapter is 145mm so it screws onto the Wonderpana; just be sure to get the Tamron specific adapter

Q: 2. Will this filter fit the DJI Inspite 1 Camera?

A: It can fit but should not be used. The weight of the filter will throw off the calibration and make the Gimbal not function properly.

Q: 3. Will this fit the sigma 150-600 lens?

A: Yes, it will.

Q: 4. Is the front ring of this Urth 72mm CPL filter threaded to accept other 72mm accessories ?

A: Yes, this 72mm Urth Circular Polarizer Filter is threaded in front to accept other 72mm accessories.

Q: 5. Is this filter multi-coated? What is the difference between this filter and the Hoya 43mm NXT Circular Polarizer Filter (B&H # HOCPN43 MFR # A-NXT43CRPL)?

A: This polarizer is not multi-coated. The difference between this filter and the NXT filter is that Hoya NXT filters have over 97% average light transmission, and are constructed from heat-resistant, high-transparency optical glass.

Q: 6. What is the filter factor, i.e. how many stops of light are reduced?

A: The filter factor of the Sony 82mm T* Circular Polarizer Filter is 1.6x, i.e., 3 stops of light are reduced.

Q: 7. WIll this fit on the NEW 70-200 mm 2.8 II lens with the lens hood attached?

A: Yes Sony 77mm T* Circular Polarizer Filter will fit on that lens with lens hood attached.

Q: 8. what is filter thickness?

A: I REALLY DO NOT HAVE A DEMININSION IT IS THE SLIM FILTER THAT IS ALL I CAN TELL YOU.

Q: 9. does this fit a sony sel55210 lens?

A: The Sony E 55-210mm lens uses a 49mm filter. The Hoya 49mm NXT Plus Circular Polarizer Filter, BH # HOCPNP49 is a great alternative. https://bhpho.to/3fMdm0B

Q: 10. 1. Can this circ-polarizer be stacked with a wonder-pana solid ND filter? e.g. using both polariser and ND-8 filter (or ND-32 filter) together? 2. If they can be stacked, will vignetting be observed on the Nikon 14-24 with two circular filters stacked? 3. Can we stack a circular wonderpana 145 filter with their rectangular 66 graduated ND filters? 4. If we can stack a circular with rectangular GND, will vignetting be observed on the Nikon 14-24 with total 2 filters (1 circular and 1 rectangular)?Thank you!

A: WonderPana 145/66 system allows stacking of one round filter like the polarizer and one rectangle filter or two rectangle filters. With the adapter for the Nikon 14-24 lens you can use this set up on that lens.It is designed not to vignette.
