PolarPro 77mm Variable ND 2-5 stop – Peter McKinnon edition

PolarPro 77mm Variable ND 2-5 stop

PolarPro has released the new king of filters. Developed in collaboration with Peter McKinnon, the filter series is of the highest quality and is a clear departure from traditional adjustable ND filters. By keeping the adjustment range of the filters moderate, maximum image quality has been achieved without colour aberration, distortion or cross-polarisation. As these filters are mainly used for video, it is particularly important that no headache-causing colour aberrations are introduced into the material. Often cheap ND filters will leave a slightly greenish ”film” on the image, still images can easily be corrected with a grey card. In video editing, however, this feature causes considerably more work and time. Peter Mckinnon is particularly known for his videos, and certainly wouldn't have put his name on a product that wasn't suitable for the job.

A stop means basically one aperture or dividing the shutter speed by two, i.e. 2-5 stops is equivalent to dimming the camera by 2-5 apertures / or dividing the time by 2-5 times. As an example, let's take a very common 50mm f/1.4 lens, in bright sunlight the lens will produce a 1/50 stop and an aperture of f/22 at ISO 100. Of course, this is not the most desirable aperture for many people, so the amount of light entering the lens needs to be dimmed. Deciding that you want to set the aperture to f/4, you can now calculate from the columns above how many times you need to "stop down" to get to the desired aperture. The answer in this case is 5, so at this maximum aperture of the filter you will reach the desired aperture. So if you want the aperture any more open/larger, you will have to substitute PolarPro Variable ND 6-9 stop a dimmed model. We recommend that all photographers buy both to make sure you get the shutter speed and aperture you want.
