Genesis Gear Step-Up redukčný krúžok 25mm na 30mm strieborný

This step-up ring bridges the gap between 25mm lens threads and 30mm filters, letting you use larger accessories on compact optics without vignetting. Its solid aluminum construction ensures a precise, wobble-free fit every time.

Advantages

Machined from a single piece of anodized aluminum, the ring adds negligible weight to your setup while resisting corrosion and wear. The slim profile keeps your lens’s field of view intact, and the silver finish matches most metal lens barrels.

Suitable for

• Prime lenses with 25mm front filter threads
• Vintage or compact lenses needing modern 30mm filters
• Macro and close-up photography with stacked filters
• Videography rigs using 30mm ND or CPL filters
• Protecting lens threads from frequent accessory changes

Key specifications

• Male thread: 25mm (attaches to lens)
• Female thread: 30mm (accepts filter or accessory)

Recommendations

Pair with a 30mm UV filter for permanent lens protection, or stack with a 30mm polarizer for landscape work. Keep the threads clean and avoid over-tightening to preserve the anodized finish.
