This LEE85 Polarizer Filter - LEE Filtersfrom LEE85 Polarizer Filter - LEE Filtershelps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface while creating a warm cast over an entire image. This combined effect can be obtained under daylight when this filter is used on a film camera system with daylight film installed, or on a digital camera system with its daylight white balance setting selected. Mounted within a durable and lightweight fiberglass frame, the LEE85 Polarizer Filter is designed to snap directly onto a LEE Filters LEE85 Filter Holder's installed guide blocks, allowing it to be used without occupying any of the filter slots created by the guide blocks.

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 polarizer filter arranges, and filters, this directionally polarized light perpendicularly to the reflected light, providing 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 polarizer 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.

For clarity and color fidelity, the LEE85 Polarizer Filter is constructed from optical glass and includes a padded pouch for storage and transport.

Q: 1. Will this work with the B&H 100mm filter holder (with the correct adapter)?

A: I can only assume it would. I have been using Lee's Lens hood with built in filter holder for years and highly recommend it.

Q: 2. Will this fit on a Sigma 20mm Art lens for Nikon?

A: I'm sorry, no, the lens has no filter threads. You will need to get a filter system specifically for this lens. Click the link below to view; https://bhpho.to/38uBbFp

Q: 5. Does this filter have a gasket on it's backside to help with light leakage?

A: Yes it does

Q: 6. Do the Lee Seven5 filters have a different degree of hard and graduated transition from the full size Lee filters? Or, is it just the physical size of the Seven5's that is different? The reason I'm asking is that I have the full Lee kit in 100mm filters that I use with my Fuji system. It works fine. Is there any advantage/difference other than physical size?

A: I use the 100mm and Seven5 Lee grads, on full-frame DSLR and compact Four-Thirds cameras respectively. Comparing the 100mm and Seven5 grads side by side, I see that the Seven5 filters are not just the 100mm grads cut to a different size. Rather, the Seven5 filters are fully scaled down, both the size and the graduation pattern, to be appropriate to the smaller lenses that they'll typically be used on. So, comparing the fade zone in the graduation in the two filters in say 0.6 Soft specification, you see that the Seven5 fade zone is shorter than in the 100mm filters. In this way, presumably you should get a similar graduation effect in your images with both the larger lenses you'll typically be using with the 100mm filters, and the smaller lenses you'll typically be using with the Seven5 filters. This matches with my experience with the two systems.

Q: 7. I have a Nikon D5300 with a 52mm lens. Does the adapter ring go on my lens and then the filter holder is attached to the ring? How is the polarizer attached to the filter holder, is it magnetic or does it go in a slot?

A: Yes, the LEE Filters 52mm Wide-Angle Lens Adapter Ring for 100mm System Filter Holder, B&H # LEARWA52, included in the above LEE Filters 52mm Wide-Angle Adapter Ring with LEE100 Filter Holder would screw into the 52mm filter threads on the front of your lens. The filter holder would then attach to the filter ring. The LEE Filters LEE100 Polarizer Filter, B&H # LE100PL, would be a polarizer filter that snaps directly onto a LEE100 Filter Holder's guide blocks without occupying a filter slot. As an alternative, the LEE Filters 105mm Polarizer Ring for LEE100 Filter Holder, B&H # LE100PLR, is a snap-on adapter ring that allows you to use a polarizer filter with 105mm filter threads on the filter holder. https://bhpho.to/3ixgBNQ https://bhpho.to/3GRraET

Q: 8. can these be used to warm up par 38 led bright white floods?

A: Yes these CTO filters can be used to warm an LED light source with a cooler color temperature.

Q: 9. Does anyone have a comparison on the Super Stopper compared to Lee's ProGlass 15 stop filter? Almost twice the price, is it worth it?

A: The LEE Filters 100 x 100mm ProGlass IRND 4.5 Filter (15-Stop) B&H # LEPGIRN15100 is more expensive because it combines two filters in one. Not only the ND but it also has an IR filter as well. Because digital sensor are susceptible to the infrared that get through the ND, this helps to keep your blacks from going to a very-hard-to-correct magenta color shift.

Q: 10. Does this filter fit the NiSi 100mm System V5 Filter Holder Kit?

A: Not sure, I used the Lee filter holder
