The blue (B2) half filter is extremely useful in landscape photography, but it can also be used in many other types of photography. Allows you to change the color in a selected part of the image. The blue (B2) half filter can be very useful, e.g. when the sky is gray and uninteresting, and the polarizing filter does not work. The filter in the colored part limits the amount of light entering the lens by 1⅔ degree of iris (1⅔EV). Z-PRO filters and accessories are designed for professionals and amateur photographers seeking the highest quality products without compromising on quality. This system provides much greater configuration options due to the possibility of modifying the holder depending on the needs. Each element of the Z-PRO holder can be freely moved or removed. Thanks to this, there is no danger of vignetting filters at small focal lengths. Z-PRO system filters are 100mm wide, so they can be used on lenses with a diameter of up to 96mm. The length of the gradient filters is 150mm while the full filters are 100mm.
