Close-Up Filter for Professional Photography
The Schneider CF Diopter Spot 50 +1 is a 138mm drop-in filter designed for professional photographers seeking creative close-up effects. It fits matte boxes that accept 138mm filter cells, providing a convenient drop-in workflow. The filter creates a sharp central area surrounded by a gradual transition to a softer periphery. This optical design guides the viewer's eye toward the centre of the frame.
Controllable Effect Strength Under Sustained Use
The filter's visual impact varies based on the selected diopter strength, the 50mm plain area diameter, and the lens focal length in use. This +1 diopter variant offers a specific strength level within a range that includes +1/2 and +2 options for different creative requirements. Photographers can adjust the intensity of the dream-like aesthetic by changing lenses or aperture settings during a session. The effect remains consistent across extended shooting periods.
Drop-In Mounting for Matte Box Compatibility
Built as a 138mm drop-in filter cell, it slots directly into compatible matte boxes without the need for screw-in threads or adapter rings. The construction centres on a polished 50mm plain area that delivers a clear, in-focus zone for the primary subject. This design supports quick filter changes on set, maintaining workflow efficiency during production. The filter is supplied new and ready for immediate professional use.

Questions about this item
Will the filter generate extra heat or consume power during long shooting days?
No — it is a passive glass filter with no electronics, so it produces no heat and draws no power.
What matte-box or holder do I need to mount this 138mm drop-in cell?
Any matte box that accepts standard 138mm drop-in filter cells will hold it securely.
Does the +1 diopter strength work with older manual-focus lenses I already own?
Yes — the +1 strength simply adds close-up magnification and functions with any lens that fits the matte box.
