Description

This product is also compatible with DJI Phantom Pro V2.0 drone.

Advance Drone Filters IRND kit is a convenient set of 4 IRND filters compatible with DJI Phantom 4 Pro/Advanced drones. Each filter features a different density, to be suitable to any kind of light intensity conditions.

The frame design pursues for maximum light and does not affect the drone’s gimbal or flight operations. Being a screw-type, it also secures the filter to the drone’s camera with no risk of falling off.

IRND kit filters also incorporate an anti-reflection and water-repellent coating. For all those demanding for high quality aerial footage.

Why IRND filters are so important

SHUTTER SPEED

For natural and smooth looking motion

In video shooting, it is fundamental to keep the shutter speed fitting the frame rate setting, that is, to keep it equal to double the frame rate for optimal results. This is because, unlike still photography, an excessively fast shutter speed may create a jarring effect and produce afterimages that will not look good at all in the final video.

As you can see from the image below, unlike still image, video clip is made of a sequence of still images. With low shutter speed, each still image will blur but will look smooth in the video sequence. On the contrary, a higher shutter speed will capture the object solid and sharp, but once in a video sequence all objects will appear separated, creating jarring and unnatural looking motion.

By using IRND filters, the shutter speed can be adjusted to the proper value to get that natural and smooth looking motion requested in video footages, as shown in the image below.

APERTURE

For optimal exposure and resolution

Drones are mostly used outdoors in daytime, high-lit environments. In these light conditions, as ISO setting should be fixed at the minimum level of ISO100, setting the aperture remains the only way to adjust exposure and thus avoid overexposed images.

When shooting videos in high-lit environments high above the ground and with related to frame rate shutter speed, you will need IRND filters to obtain the optimal aperture.

The image below shows the difference between an overexposed video footage and a video shot with appropriate aperture setting during a sunny day in a snowy mountain area.

Also, without IRND filters, any f/11 and upward aperture value will cause diffraction effects that will generally reduce the overall resolution of the image. It can be particularly experienced when shooting in 4K mode. Extremely close aperture may also create unwanted flares and ghosts on the image, as shown below.

Features

ACCURATE NEUTRALITY

High-quality IRND filters are required to be extremely and accurately neutral to prevent color shift or IR pollution from affecting the final image.

Accurate neutrality of Kenko IRND filters is achieved by adopting Accu-ND Technology that is exclusively developed for DSLR camera filters. Accu-ND Technology provides constant and fine-adjusted light density within a wide spectrum range, including the infrared area (400nm-1000nm).

JUST-FIT FRAME and SCREW TYPE MOUNT

Made of ultra-light aluminum alloy to reduce the load on the camera, Kenko IRND filter is designed in an exclusive just-fit in size frame that does not affect the gimbal and flight performance of the drone.

The knurling edge on the frame also aims to provide quick and secure attaching. The screw-type mount will not allow the filter to fall off during the flight, thus guaranteeing long time, safe and reliable use.

4 in 1 kit in ALL-WEATHER PROTECTIVE CASE

Kenko Advanced Drone Filters IRND kit contains 4 filters of different density to choose from depending on the light conditions at the shooting location. Choosing the right density value will allow fine adjustments of the camera setting according to the different light conditions, thus avoiding diffraction and obtaining optimal exposure of the image.

Also, for better and convenient utilization in outdoor environments, Kenko Advanced Filters IRND kit comes within an all-weather case that will keep filters all together and protect them from moisture and dust, rain or snow.

EASY TO MAINTAIN

Anti-reflection multi-layer coating of Kenko IRND filters is blended with a water-repellent layer. This ensures protection from fingerprints, smudges, dust, thus making filters easy to clean and maintain them in ready-to-use conditions.

How to choose the right IRND filter

When shooting video it is recommended to use aperture stepped 2-3 stops up from wide-open position. In high-lit environments above the ground and with related to fps mode shutter speed, you would need IRND filters to obtain the optimal aperture.

The table below can serve as a basic guide to choose the right IRND filter.

For example, at a shutter speed set at 1/125s you will get f/11. You will then need to attach an IRND4 to step down to f/5.6, or IRND8 to step down to f/4. Or, with the aperture set at f/5.6 and the frame rate at 60 fps, you will need IRND4 filter to slow shutter speed from 1/500 to 1/125.

As you can see, IRND4 filter must be commonly suggested to be attached by default as a necessary item in a sunny day.

To achieve the best resolving performance of the drone’s camera with max f/2.8 aperture, the optimal aperture value is suggested to be at f/4 or f/5.6.
