    Product Description

    We can say a bit more about these filters. If you have an Achromat, these will significantly help with clarity and fringing as well. It allows a lot of the light through while still eliminating the purple fringing. There is also less of a color shift compared with the #12 filter. It may also darken your suburban sky.
