BEIZMEI Camera Filters Ring 43–67mm step-up ring for UV, ND and CPL filters
Product description
If you own a lens with a 43mm filter thread but your kit of UV, ND or CPL filters is built around a different size, a step-up ring is the simple fix. The BEIZMEI Camera Filters Ring is a CNC-machined adapter designed to let you fit 67mm filters (and similar accessories) onto a lens with a 43mm thread.
Quick overview
On paper, this kind of 43mm–67mm step-up ring is all about one job: increasing the apparent filter/adaptor diameter so you can use filters and accessories that don’t match your lens thread size. The listing explains the logic clearly: the first number refers to your lens thread size, the second number refers to the filter/accessory size. In this case, 43mm (lens thread) becomes 67mm (filter size), which should help you avoid the common frustration of buying the “right” filter but the “wrong” thread.
What it’s for (and a real-world example)
Imagine you’re heading out for a coastal shoot. Your lens has a 43mm filter thread, but your neutral density (ND) filter and a polariser (CPL) are both 67mm. Swapping parts every time you want to change filters is annoying, and it’s easy to mis-match sizes when you’re ordering.
With a step-up ring like this, you can mount the ring to the front of the lens, then attach your 67mm UV/ND/CPL filters to the ring. It’s also described as useful for other front-mounted accessories such as a lens hood or additional lens. It won’t magically turn a 43mm lens into a different lens—rather, it helps you make the accessories in your existing filter kit physically fit.
Key features and build
The ring is described as CNC machined, with a black matte galvanised finish intended to resist corrosion and other abrasive conditions that can come with outdoor photography. There’s also mention of a metal sealing ring and a tight fit, plus laser sources and durability, and compliance with RoHS environmental standards.
Worth noting: the practical feel of a step-up ring comes down to tolerances and fit quality. Based on the description, BEIZMEI is leaning into a sturdier, metal build (not a flimsy lightweight adapter), but you’ll still want to confirm your lens thread size is truly 43mm before ordering.
Compatibility: what you can connect
The product description frames compatibility around two thread sizes: - The lens side is for a 43mm filter thread. - The accessory side is for 67mm filters (UV, CPL, ND are explicitly mentioned).
It also advises checking how the filter thread size is marked—either printed under the lens cap or somewhere on the lens barrel. That’s genuinely important, because the wrong size won’t fit, and step-up rings don’t offer much “give” if the thread pitch or diameter is off.
Where it shines (and where it may fall short)
This is a good match if you’re trying to rationalise your filter collection—keeping to one filter diameter (67mm) while still being able to use them across lenses that have different thread sizes (like a 43mm lens). It’s also the kind of accessory that can keep your workflow simple: ring goes on once, then you swap filters as needed.
It might not be the best choice if: - Your lens doesn’t actually have a 43mm filter thread (in which case it won’t screw on properly). - You’re looking for something that changes optical performance—this isn’t that. It’s a mechanical adapter, so expect a straightforward fit/compatibility role, not creative improvements. - You’re using a setup where clearance matters a lot (for example, some hoods or chunky filter stacks). The listing talks about accessories in general, but doesn’t state fit clearance for every possible combo.

Should you buy it?
A solid pick if you have a 43mm filter thread lens and you want to use 67mm UV, ND and CPL filters (and potentially other front accessories) without buying a separate set of filters for every thread size. It makes sense if you’re building a more consistent filter kit and prefer to adapt the lens side rather than replace filters.
You may want to skip it if you’re not certain your lens really is 43mm, or if you’re trying to solve a problem that a step-up ring can’t address (like wanting an optical change). For best results, double-check the lens thread marking under the cap or on the barrel before committing.
Mini FAQ
1) What does “43–67mm” mean on a step-up ring?
The first number is the lens thread size, and the second number is the filter/accessory size. Here, it’s 43mm on the lens side and 67mm on the filter side.
2) Will this fit any camera lens?
It should fit lenses that have a 43mm filter thread. The description says it’s compatible with all camera lens brands of 43mm diameter on the lens thread side, but you still need the exact thread size.
3) Can I use UV, ND and CPL filters with this?
Yes—the listing specifically mentions UV, ND and CPL filters on the 67mm side.
4) How do I confirm my lens thread size?
Look under the lens cap or on the lens barrel where the filter thread size is printed or written.
5) Is it designed for outdoor use?
The black matte galvanised finish is described as resistant to corrosion and abrasive conditions often found outdoors, so it’s aimed at more than just indoor studio handling.
Final verdict
If your filter stash is mainly 67mm but you’ve got a 43mm-thread lens, this BEIZMEI step-up ring is exactly the kind of practical adapter that prevents wasted purchases and makes filter swapping easier. Just don’t rush the thread-size check—if the lens isn’t truly 43mm, it won’t be the right mechanical match.
