A new standard in ND filters for cinematography

Our filters are remarkably neutral, eliminating infrared pollution and ensuring all colours remain absolutely accurate and true. This simplifies workflows, saves time, and enables cinematographers like you to focus on your creative goals.

And you can be sure they won’t let you down. Manufactured from 4mm-thick, optically flat, scratch-resistant glass and edged with a metal rim, our ProGlass Cine IRND filters are durable and long-lasting.

Available in Two Sizes and Seven Densities

    I was extremely impressed by the true stop every ND gave me throughout the whole range, right up to ND2.1. Every time I changed the filter, I deliberately preset the stop to check the accuracy, and it was always spot-on.

    Also, I didn’t notice any colour shift when changing filters or combining two filters, something I was often struggling with when using other brands. This should make life easier when shooting multiple camera setups and consequently will help the grade a little further down the line.

    The main advantage of these filters is their neutrality, especially when using 4 stops (1.2ND) or above.

    When I use other IR ND filters, I normally have to compensate for a colour shift in the grade, but with these I haven’t seen any noticeable colour shift. They are by far the best front-of-camera ND filters I have used.

    I recently used these ND filters on a television project shooting with Arri Alexa XT cameras, and they performed beautifully.

    The true colour rendition was spot-on throughout the range, making the grading process easier when using multiple cameras. The several filter sets I used matched exactly on ND level and IR cut. The high quality and robust construction make them a perfect tool for digital cinematography.
