Ultimaxx 40.5mm Close-Up Macro Filter Set +1 +2 +4 +10 Diopter

40.5mm Macro Filter Set for Close-Up Photography

This four-piece set provides +1, +2, +4 and +10 diopter filters that screw onto any lens with a 40.5mm thread. Photographers can use each filter alone or stack them to reach the magnification required for small subjects such as flowers, insects or product details. The multi-coated optics are designed to maintain clarity across digital cameras and video cameras.

Stacking Limits and Optical Constraints

Adding multiple diopters increases magnification but also narrows the working distance between lens and subject, making lighting and focus more critical. Each extra element introduces additional glass surfaces that can reduce contrast or introduce flare if the coatings are not kept clean. The combined diopter value determines the closest focus point, so the photographer must decide the trade-off between size and image quality for each shot.

Check Thread Size and Filter Compatibility

Verify that the front of your lens carries a 40.5mm filter thread before ordering; other diameters will not fit without a step-up or step-down ring. Ensure there is enough clearance on the lens barrel for the filter frame to seat fully without vignetting at wide angles. The included wallet protects the filters during storage and transport.
