Step-up Adapter Ring Marumi 49mm to 62mm SB6204 for Camera Lenses

Marumi Step-up Adapter Ring 49mm to 62mm (model SB6204) converts a lens front thread from 49 mm to 62 mm so larger 62 mm filters, hoods and other accessories can be mounted on lenses with a 49 mm thread. The adapter is constructed from metal to provide a stable, secure connection and accurate alignment between the lens and the attached accessory. It enables photographers to use a single set of filters or accessories across different lenses without altering the lens threads.

Advantages

This step-up adapter ring allows the use of 62 mm filters and screw-on accessories on lenses with a 49 mm thread, reducing the need to buy duplicate items. The metal construction improves durability and maintains concentric alignment, minimising vignetting and ensuring reliable attachment. The slim profile helps preserve the field of view and reduces the risk of mechanical interference with lens hoods or built-in lens elements.

Suitable for

• Mounting 62 mm screw-on filters (polarizers, ND, UV) on 49 mm threaded lenses
• Attaching 62 mm lens hoods or protective caps to smaller lenses
• Sharing 62 mm accessories between different camera bodies and lenses

Key specifications

• From thread diameter: 49 mm
• To thread diameter: 62 mm
• Material: metal construction for durability
• Type: step-up adapter (non-reducing, non-rotating)
• Profile: slim design to minimise vignetting

How to use

Screw the adapter ring onto the lens front by matching the 49 mm internal threads and rotating it clockwise until it is hand-tight and seated evenly. Then screw the 62 mm filter or accessory onto the adapter’s external thread by rotating it until secure. For filters that require rotation (such as circular polarizers), attach the filter last so it can be rotated independently when needed. Avoid overtightening to prevent cross-threading or damage to the threads.

Usage recommendations

Use the adapter when you want to standardise on 62 mm filters and accessories across lenses with smaller threads. Remove the adapter when not needed to keep the lens front compact and to prevent additional points of contact. Check compatibility with wide-angle lenses: for very wide focal lengths, verify that the adapter plus filter do not introduce vignetting. Store metal adapters in a dry place to avoid corrosion and wipe threads clean before mounting accessories.
