SUMMARY
PolarPro has introduced the Split 50 Filter, a circular camera accessory that appears to have half its glass missing, but this is intentional. The filter functions as a split diopter, enabling two subjects at varying distances to be in sharp focus at the same time. This type of filter uses a magnifying lens on one half of the frame to bring distant subjects into the same focal plane as closer subjects on the clear side. While often used in cinematography to keep multiple subjects in focus, PolarPro suggests it can also create visual emphasis and tension.
