40.5mm to 67mm Step Up Ring Filter Adapter for Canon/Nikon/NEX M4/3 (Aluminium)
Product description
What is it and what problem does it solve
A 40.5mm to 67mm step up ring filter adapter is a small, aluminium ring that screws onto the front of a camera lens with a 40.5mm filter thread, allowing you to fit filters, hoods or other front-end accessories with a 67mm thread. In practice, it helps you reuse existing 40.5mm filters across lenses that take 67mm accessories, reducing the need to buy multiple filters for different lenses. It’s a modest addition to a camera bag, aimed at shooters who want flexibility without swapping lenses.
What you get and what it’s made of
From the available description, the ring is 100% brand new with a claim of top‑line quality and aluminium construction. The material choice suggests durability and lightness, which matters when you’re stacking accessories on the front of a lens. There are no additional technical specs provided about tolerances, coating or exact weight, so it’s sensible to treat it as a basic, budget-friendly option rather than a premium precision piece.
How it fits and how you use it
The ring threads onto the lens side with 40.5mm, and the other side accepts 67mm filters or attachments. It’s designed to stay in place during normal shooting, subject to typical handling and care for aluminium mounts. It isn’t a zoom or motorised accessory, its role is simply to adapt thread sizes so you can keep using your existing 67mm filters on a camera with a 40.5mm front thread.
The good bits and potential drawbacks
What stands out on paper is the simplicity and value proposition: reuse existing filters, avoid buying new 67mm components for every lens, and keep your kit lean. On the downside, the description doesn’t specify fine tolerances or thread-fit details, so you might encounter occasional snugness or slight play if the threads aren’t perfectly matched. It’s also a generic adapter, so it won’t add any optical benefit beyond compatibility. If you’re chasing ultra-tight manufacturing tolerances or a premium finish, this may not tick every box.
Who this is for
If you own lenses with 40.5mm filter threads and you already use 67mm filters or hoods, this adapter makes practical sense. It’s worthwhile for hobbyists or hobbyist professionals who want to maximise filter utilisation and avoid cluttering up multiple filter sets.
When it’s worth considering and when you might skip it
Consider this if you frequently swap between lenses with 40.5mm and 67mm front elements and you want to keep using the same filters, it’s a cost-effective way to extend filter compatibility. You might skip it if you rarely use filters, or if you require guaranteed precision and a high-end finish from a single brand. In those cases, a purpose-built, higher-spec adapter or a set of matching lenses could be more appropriate.
What to check before buying
- Confirm your lens has a 40.5mm filter thread and your filters/attachments are 67mm.
- Check that the product is described as aluminium and brand new, with no contradictory notes in the listing.
- Consider whether you need any added features (like stepped rings with anti-slip surfaces or coatings). The provided description doesn’t mention these, so manage expectations accordingly.
Practical usage example
Imagine you have a stack of 67mm filters for a compact travel lens with a 40.5mm thread. With this adapter, you can attach those filters to a different lens that has the smaller thread, which saves you from buying duplicate filters and keeps your kit lighter at the same time. It’s a small upgrade, but it can shave a bit of time off on-location set-ups when quick changes matter.
FAQ
- Q: Is the adapter made of aluminium? A: The listing claims aluminium construction, but no technical specifications are provided.
- Q: Will it affect image quality? A: There’s no optical element in the ring itself, so there’s no direct impact on image quality aside from compatibility.
- Q: Does it come with filters? A: No, the description refers to the ring and its compatibility with 40.5mm and 67mm components, no filters are included.
Is it worth it?
Is it worth it? A solid pick if you need to bridge a 40.5mm lens to 67mm filters or accessories and you already own 67mm items. It’s a practical, low-cost way to increase flexibility without investing in new gear. It may not be the best choice if you require high-precision, premium-grade hardware or if you don’t use filters regularly. In everyday terms, it’s a sensible option for value-conscious shooters looking to streamline their kit.
