Vivitar 55-58mm Step-Up Ring Adapter 3-pack camera accessory

Three-Pack Step-Up Rings

This three-pack of Vivitar step-up rings converts a 55 mm lens thread to a 58 mm thread, letting photographers share one set of 58 mm filters, hoods or converters across every 55 mm lens they own. Each ring is machined from anodised aluminium with a slim profile that resists cross-threading and wobble.

Buyers needing 55-to-58 conversion

The kit suits shooters who own multiple 55 mm threaded lenses and want to standardise on 58 mm accessories without buying separate adapters for each lens. Photographers whose lenses use any other thread diameter, or who need step-down instead of step-up, should look at a different adapter.

55 mm to 58 mm thread conversion

The single specification that decides fit is the 55 mm male to 58 mm female thread change; the lens barrel must show 55 mm and the accessory must accept 58 mm, otherwise the ring will not engage.
