PolarPro Chroma VND/PL McKinnon Series Filter

This filter is designed specifically for an 82mm thread size. If your lens has a different diameter, you will need to use a step-up ring to attach it, though keep in mind that using rings can sometimes increase the risk of vignetting on wider lenses.

The McKinnon Series is engineered with stop-limiters to prevent the cross-polarization 'X' pattern that plagues many cheaper variable ND filters. You can rotate the filter freely within its 2-5 stop range without worrying about uneven exposure artifacts.

Because this filter uses high-quality glass and integrates both functions into a single piece of glass, it maintains excellent sharpness. It avoids the optical degradation and potential vignetting often caused by stacking a separate ND filter on top of a polarizer.

Yes, the filter is designed to accept standard lens caps. You can leave it on your lens during transport and simply snap your cap over the front element.

The filter features two independent rings: one for the variable ND and one for the circular polarizer. You can adjust your shutter speed settings first, then rotate the outer ring to dial in the desired level of reflection reduction without affecting your exposure.

This specific filter offers a 2-5 stop range, which is optimized for video and bright-light photography. It is not intended for extreme long-exposure work, such as smoothing out waterfalls or clouds in broad daylight, which typically requires a much higher stop count.
