The Schneider 138mm (+1/2, +1, +2, +3) Split-Field Diopter Kit shortens the close-focusing distance of a lens. It can be used with fixed focal length (prime) or zoom lenses. This allows the camera to focus closer to the subject and achieve a larger image size while bringing out the sharpest details in even the tiniest subjects.
Diopters are the simplest and least expensive method of close-up photography. Have you ever wished that your lens could focus closer than it does? Imagine that you could put a magnifying glass in front of your camera’s lens. With Schneider Diopters, you can dive into the world of macrophotography with a minimum of expense and with a maximum of confidence.
