43mm to 55mm Step-Up Filter Adapter Ring

Key features

This aluminium step-up adapter ring turns a 43mm lens thread into a 55mm accessory thread, letting you fit 55mm filters, hoods and threaded converters without buying duplicate kit. It feels solid in hand and resists corrosion, so it suits everyday outdoor shooting where equipment sees frequent use. If you need to use a 55mm UV or CPL filter on an older 43mm lens, this adapter is a straightforward way to extend compatibility and save cost.

Specifications

• Name: 43mm to 55mm adapter
• Material: Aluminium alloy
• Size: 43mm to 55mm
• Compatibility: All 43mm lenses with 55mm accessories
• Finish: Corrosion resistant glossy metal

Benefits

The simple metal design keeps weight low and offers a snug fit according to the manufacturer, reducing wobble between lens and accessory. It means you can share a favourite 55mm filter across multiple lenses with smaller front threads, which is handy on location or when travelling light. Do note that the adapter does not change optical properties, so any vignetting or image changes stem from the filter or converter used.

How to use it

Screw the ring onto the front thread of your lens until it seats flush, then attach your 55mm filter or hood as you would normally. Check the lens cap or barrel for the Ø43 marking to confirm the lens thread before buying. It’s a practical, low‑cost way to increase the versatility of existing filters and accessories.

AMOTOK 43mm to 55mm is shown as the compatible ring according to the manufacturer, and the metal sealing ring and laser-etched markings are intended to improve durability. Bear in mind that proper fit depends on confirming the lens thread size first.
