The Tiffen 125mm Coarse Thread, Non-Rotating Warm Linear Polarizer Filter can be applied to create a warm cast over an entire image while helping 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.

The warming effect of this filter 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. This filter's overall coloration reflects a mired shift value of +45.

A linear polarizer differs from a circular polarizer in that it does not contain an additional quarter wave plane. The addition of a quarter wave plane is to circularly polarize 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, in-camera auto focus and exposure accuracy become skewed during use. When the light becomes circularly polarized, it permits the use of these functions.

This filter is recommended when not using in-camera exposure metering or autofocus, is non-coated, and has approximately 40% average light transmission. Constructed from optical glass for clarity as well as color fidelity, the Tiffen 125mm Coarse Thread, Non-Rotating Warm Linear Polarizer Filter features an aluminum-alloy filter ring that does not rotate. The intensity of the polarization effect can be adjusted with the use of third-party or custom filter holders.

Q: 5. is this compatible with the canon r5c?

A: Yes, fit right on like the R5.

Q: 6. Hi, is it possible to take high resolution digital video with this telescope?

A: Yes, that is more of a function of the camera you choose, and the distance to the object, light conditions ETC. It depends on what you are shooting as well, Astrophotogaphy - good, Sports photography totally not appropriate.

Q: 7. can it rotate both ways? would prefer the screen to flip up instead of down, anyone know of any that would fix my problem?

A: The Benro QRB95 Quick Rotating Bracket can only be rotated so the shutter button is up on top. You can use this Alzo instead: https://bhpho.to/3yS6fQI. You can mount the camera on the Alzo Flipper bracket from either side and thus choose to have the right side or the left side of the camera on top.

Q: 8. Can I use a 7mm eyepiece with it?

A: Yes as long as it is 1.25".

Q: 9. Do I have to pay in advance?

A: Yes when you place a Back Order you do need to put down a Payment. However, the order is charged when the Item comes into stock, and ships out to you.
