We should compensate about 5-6 stops of light with the Hoya 62mm R72 Infrared Filter.

The Hoya R72 Infrared Filter blocks about 5-6 stops.

The Hoya 62mm R72 Infrared Filter is compatible with the K70. As for results it will vary depending on settings and the scene/shot.

The sample image on our web site was provided to us by Hoya and is labeled Simulated so I do not know what was done to get it to look the way it does. Infrared photography does not include visible light which includes the colors we see. Near-infrared image capture occurs in the range from about 700 nm to about 900 nms. The Hoya R72 Infrared Filter is a specialized filter that blocks all visible light up to 720nm, enabling recording of subject matter and scenes that are not visible under normal conditions. When captured with a digital camera or IR color film false-color is recorded depending on the IR the subject is reflecting. Film based IR photography offered both color and B&W emulsions. Digital cameras will record false-colors which can be edited in post processing to the color scheme of your choice or converted to a grey scale (B&W) image.
