The Heliopan 37mm 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.

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. If I put this filter on a Nikon Z 24-70mm "S" lens, will the lens hood fit (on and reversed)? Will I see vignetting? Thanks!

A: The Heliopan 82mm Circular Polarizer SH-PMC Filter is not thin so it would vignette the 24-70 lens. This B+W filter would be a better option because ti is thin and will work with the hood for your lens: https://bhpho.to/31bpvbp

Q: 2. is it compatible with canon 18-135 lens?

A: If you look at the front of the lens, after the focal length and the F stop value there will be a single 2 digit number, that is the size of the filter you need, the number is usually preceeded by a 0 with a slash through it.

Q: 4. 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: 5. Will this fit Canon rf 24-105 f4 lens?

A: Yes this filter kit is compatible with the Canon RF 24-105mm f/4L IS USM.
