The Heliopan 43mm Slim Circular Polarizer Filterhelps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. This results in a noticeable increase in the saturation of skies and foliage, as well as clearer imagery when photographing in hazy conditions. A circular polarizer differs from a linear polarizer in that it supports full use of a camera's autofocus and auto exposure functions.

The filter is constructed using high quality Schott glass, which maintains optical clarity and contrast to help render scenes with greater fidelity and resolution. The SH-PMC multi-coating provides a total of 16 coatings, 8 per side, for significant reflection reduction (below 0.2%) as well as dust and moisture repellence for easier cleaning.

This filter features a brass mounting ring that is demarcated with calibration dots to help with finding consistent rotational positioning when TTL viewing is not possible. The ring also features a slim mount design, measuring 5mm-thick, that helps to prevent vignetting when used on wide-angle lenses. It does not feature front threads for mounting additional filters or lens caps.

Minimize Reflections and Glare    Reduces Haze and Blue Cast in Landscapes    Enhances Color and Tonal Saturation    SH-PMC 16-Layer Multi-Coating    Slim Profile Brass Filter Ring    High Quality Schott Glass

Reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface.

Arrange and filter directionally polarized light perpendicularly to the reflected light allowing for the absorption of much of the light.

Lessens haze in distant landscapes and provides more saturated, vivid colors.

Strongest effect when used at a 90° from the sun.

SH-PMC multi-coating offers both protection to the glass and helps to maintain light transmission and image quality.

Constructed from Schott glass for high optical clarity.

Thin-profile filter ring reduces likelihood of vignetting when used with wide-angle lenses.

Q: 1. What are those index marks on the filter ring mean?

A: The index marks do not have a specific number but can help you get to the same position.

Q: 2. My Lumix LX100 is with the DMW-LFAC1 lens cap. Will this Hoya fix in well?Do you know it's thickness?I have a Cokin UV 3.3mm thickness lens and it slides/works perfectly.Looking forward to your kind reply. Thank you.

A: Yes, you could use this filter with the DMW-LFAC1 on the LX100.

Q: 3. What is the thickness of this "slim" filter?

A: This filter is 5.2mm thick.

Q: 4. What's notably different with these and the Kaesemann polarizers from only a few years ago?

A: The B+W High-Transmission MRC-Nano Master Circular Polarizer Filter (82mm) has a Nano coating that provides an improved beading effect with water for more efficient cleaning. The B+W Kaesemann Polarizer filters do not have this coating.

Q: 5. Would this fit my Zeiss 35mm lense ??

A: It depends which Zeiss lens you have, there're multiple. If you see your lens listed on the B&H site you can check the filter size in the "Specs" section.

Q: 6. What are the numbers (1-18) around outside edge of polarizer?

A: The numbers on the mounting ring are used as calibration dots to help with finding consistent rotational positioning.

Q: 7. What is the thickness of the filter?

A: The Ice Slim Multicoated Circular Polarizer Filter (100 x 100mm) is 0.08" / 2 mm, thick.

Q: 8. Hi,What is the main difference between this filter and Heliopan 46mm High-Transmission Circular Polarizing Multi-Coated Filter ?I see that the filter factor for this one is between 2.3 and 2.8For the High-Transmission version is 2.0. That means more quality for the High-Transmission one.Do both of them feature the index markings on the edge of the filter ring ?The High-Transmission one doesn't have a slim mount, does it ?!And one last question: do they have the same glass and coating ?Kind regards !

A: The main difference between the Multi-coated Heliopan 46mm Circular Polarizer and the 46mm High Transmission Circular Polarizer is the filter factor; the high transmission CP will have a filter factor of one stop, where the multi-coated has a factor of approximately 1.3 stops. Both filters feature index markings. The high transmission CP does not have a slim mount. Both filters have the same 16-layer coating, and are both produced from Schott glass.

Q: 9. Anyone using it with the auto focus on the Canon EF 100-400mm f/4.5-5.6L ISII USM Lens on a 90D body? Off brand CPL interferes.

A: Ice 77mm Slim Multicoated Circular Polarizer Filter does not interfere with any of the autofocus modes when conneting the Canon EF 100-400mm f/4.5-5.6L ISII USM Lens on a 90D DSLR camera. The camera and lens have a smooth transition even in tracking focus.

Q: 10. does this filter allow the hood of canon RF 28-70 95m lens to be taken on/off with the CPL in place?

A: Yes. The Hoya 95mm EVO Antistatic Circular Polarizer Filter does not interfere with the hood of the Canon RF 28-70mm f/2L USM Lens.
