Hoya's new HD Sq100 series is a line of filters that incorporate the newest state of the art technology. They are especially designed for professionals who want to take their photography to the next level. The range includes premium IRND filters for long exposure shots. The HD Sq100 is highly recommended for landscape, seascape, travel and social media photography.

The HD Sq100 IRND64 is a middle density IRND filter. It is especially used to add motion blur to the object in shooting conditions that usually would not allow the camera shutter speed to do so.

Made from toughened glass, the HD Sq100 is designed to endure harsh conditions during travel and adventure. The IRND nano coating for both sides of the clear optical filter glass does not only remove IR contamination, but also creates a truly neutral colour balance through its applied ACCU-ND technology. This prevents any noticeable colour cast to your images. Additionally, its water repellent and anti-reflection coating drastically minimizes the risk of random light reflections while increasing the light transmittance.

The filter glass is made of 2mm thick, toughened optical glass that provides a four-times stronger durability than common filter glass, making the filter highly recommended for usage even in extreme shooting conditions.

Stacking square filters is extremely convenient due to easy and fast handling and very low risk of vignetting. Stacking ND filters in particular is one of the most common practices in photo shooting, as it allows the photographer to easily create totally new effects in photos. For example, the combination of HD Sq100 IRND8 and HD Sq100 IRND64 will give the effect equal to an ND500 filter, which can be used to express an unreal fantasy world. Alternatively, HD Sq100 solid filters can also be stacked with HD Sq100 GRAD-S filters in order to create a motion effect while keeping the balance between light and dark in the image.HOY
