BG3 Equivalent ZB2 - UV, Blue and IR Pass Filter
These BG3 equivalent ZB2 UV, Blue and IR pass filters are excellent quality, but at a more reasonale price than their Schott equivalents. They are Chinese ZB2 Glass mounted in Plain 52/49mm filter mounts, but the quality is excellent. Out of the camera, blue skies are blue with a touch of deep purple, but this is easily corrected with a slight Hue shift of Blue. Foliage is bright yellow out of camera when you set up the White Balance on a White Subject. You can also produce excellent Black and White images as shown in the examples. Another point of interest is some lenses that suffer from Hot Spots with normal IR filters are almost completely clear with these ZB2 filters.
