ProMaster Circular Polarizing Filter

Check the front of your lens or the inside of your lens cap for a diameter symbol (a circle with a slash through it) followed by a number. If that number is 72mm, this filter will fit perfectly.

Because this is a circular polarizer, it is designed to work seamlessly with modern autofocus and metering systems. However, keep in mind that it will reduce the amount of light entering your lens by about 1 to 1.5 stops, so you may need to adjust your shutter speed or ISO slightly.

Yes, but it can be tricky. Since you need to rotate the filter to adjust the polarization effect, you will likely need to remove the lens hood to reach the filter ring, or use a lens hood that allows for filter access.

For the most dramatic effect, shoot at a 90-degree angle to the sun. Slowly rotate the filter while looking through your viewfinder or at your screen until the glare on water or glass disappears and the sky reaches your desired level of saturation.

While you can technically stack filters, it is generally discouraged as it can lead to vignetting—dark corners in your images—especially if you are using a wide-angle lens. It is best to use only one filter at a time for optimal image quality.
