Lens Step-Up/Step-Down Adapter Marumi Z 43.5 mm to 52 mm SB6200

Marumi Z 43.5 mm to 52 mm SB6200 is a lens step-up/step-down adapter designed to convert a 43.5 mm filter/thread connection to 52 mm. The adapter enables mounting 52 mm filters, lens caps or other 52 mm accessories on lenses with a 43.5 mm thread and can be used in the opposite direction to adapt a 52 mm accessory to a 43.5 mm lens. Built for precise alignment and a secure fit, the adapter preserves optical axis alignment and filter functionality when changing filter sizes between compatible lenses.

Advantages

The adapter is made to provide reliable mechanical connection between different filter thread sizes, reducing the need to purchase multiple filters for each lens. Its construction minimizes wobble and maintains concentricity to avoid vignetting or misalignment of circular filters. By allowing reuse of 52 mm filters and accessories on 43.5 mm lenses (or vice versa), it helps streamline equipment and reduce carry weight for photographers working with multiple lenses.

Suitable for

• Photographers who want to use 52 mm filters on lenses with a 43.5 mm thread
• Attaching 52 mm lens caps, hoods or close-up accessories to 43.5 mm lenses
• Creating a consistent filter setup across lenses with mixed thread sizes
• Travel and field work where minimizing gear is important

Key specifications

• From thread size: 43.5 mm
• To thread size: 52 mm
• Type: step-up / step-down adapter
• Material: precision metal construction for stable attachment
• Finish: matte surface to reduce reflections
• Compatibility: designed for standard screw-in filter threads

How to use

Screw the adapter onto the lens filter thread of the matching size (43.5 mm side to a 43.5 mm lens). Turn the adapter gently until it seats securely without cross-threading. Once attached, screw the 52 mm filter or accessory onto the exposed 52 mm thread. To use in the reverse direction, first mount the accessory on the adapter and then attach the combined assembly to a 43.5 mm lens, taking care to align threads and avoid overtightening. Inspect the connection for tightness and correct alignment before shooting.

Usage recommendations

Always check for cross-threading when attaching the adapter and accessories. Tighten by hand only; use minimal force to avoid damaging threads. For critical wide-angle or high-resolution work, verify that the adapter and filter combination does not introduce vignetting or optical obstruction. Store the adapter in a protective pouch to prevent scratches and maintain thread integrity.
