Product Highlights. MIST DIFFUSER BLACK No0.5 and No1 are recommended for different scenes. No0.5 is suitable for night scenes and backlit scenes when the sun starts to set, while No1 is more suitable for forward lit or low light situations. The soft effect is stronger when the focal length of the lens is on the telephoto side and weaker at the wide-angle side. The effect may vary depending on the type of light source and other shooting conditions like for example shutter speed. The effect seen in the viewfinder and the result of shooting (depending on print, monitor size, etc.) may differ. The final result will also change depending on the exposure compensation, so it is recommended to use exposure compensation if necessary.   1 Year Warranty
