Description
The Schneider 138mm Split-Field Diopter Kit (+1/2, +1, +2, +3) shortens the close-focusing distance across only half the frame, magnifying one side of the image while leaving the other half unaffected — useful with either prime or zoom lenses.
Split diopters are a simple, low-cost route into macro-style close-ups, effectively placing a magnifying glass over half the lens to bring out fine detail on tiny subjects without swapping to a dedicated macro lens.
