Nikon Circular Polarizing Filter - 77mm

While possible, it is generally recommended to remove it in low-light situations because the filter reduces light intake, which can force you to use a slower shutter speed.

Yes, as a circular polarizer, it is designed to work perfectly with modern camera autofocus systems and metering sensors.

No, this is a 77mm filter. You would need a 77mm-to-72mm step-down ring, though this may cause vignetting.

You can, but it is not recommended as it increases the risk of vignetting and may introduce ghosting or lens flare.

Look through your viewfinder or at your LCD screen while rotating the outer ring; you will see the reflections disappear or the sky darken as you find the optimal angle.

Ensure the filter is properly tightened and clean; verify that you are not using the filter in extremely low light which may cause motion blur due to decreased shutter speed.

Check to ensure the filter is fully screwed in. If using an ultra-wide lens, ensure no additional thick filters are stacked on top of this one.

Rotate the front ring of the filter slowly while looking through the viewfinder; the effect is most pronounced when the camera is pointed at a 90-degree angle to the light source.
