46–72mm Camera Lens Adapter & 46mm to 72mm Step-Up Filter Ring
Product description
The essentials
If you’ve got a lens with a smaller filter thread but a favourite filter (UV, CPL, ND, or even a hood/accessory) made for a larger diameter, a step-up ring is often the simplest fix. This 46–72mm camera lens adapter is designed to let a 46mm lens thread work with 72mm accessories, so you’re not forced to replace everything just because the thread sizes don’t match.
On paper, the idea is straightforward: the first number refers to the lens thread size, and the second number refers to the accessory filter size. In this case, it’s intended to take a 46mm lens and provide a way to mount 72mm filters or other compatible 72mm front accessories.
Key takeaways
The main reason to consider this adapter ring is practical compatibility. It’s built to help you share the same lens across different filter/attachment diameters, rather than buying multiple sets of filters for different lenses.
The ring is described as made from an aluminium alloy, with a black exterior finish and a matte paint treatment on the inner wall. It also mentions a corrosion-resistant, glossy approach and a design intended to mount securely to the lens while still being removable when you don’t need it.
It’s also worth noting the brand’s focus on metal parts: the sealing ring is described as a tighter fit, which is the sort of detail that can matter if you’re trying to keep things snug for everyday handling.
What you’ll notice in use
A common scenario: you have a lens that takes smaller filters, but you already own (or plan to buy) a 72mm UV or CPL filter. With this step-up ring, you can attach the 72mm filter to the front of your lens setup.
It’s the kind of add-on you’ll reach for when you want a consistent kit. Instead of swapping filters or buying multiple sizes, you adapt the lens to the accessory you already trust.
Still, keep expectations realistic. A step-up ring won’t improve the optical performance of the filter itself, and it doesn’t turn an incompatible thread into a guarantee of perfect fit—getting the right lens thread size is critical.
Where it shines (and where it may not)
This is a sensible purchase if you want one lens-adapter approach to make 72mm accessories usable on 46mm camera lenses. It’s also a good fit for people who carry a small kit and would rather standardise around filter sizes.
However, it may not be the best choice if you’re unsure about your lens thread size. The listing stresses that the lens thread size should be printed under the lens cap or written somewhere on the lens barrel, and ordering the wrong size will simply not fit.
Also, if your main priority is ultra-fine, perfectly flat mounting surfaces (where small tolerances can be fussy), you’ll still want to be careful. This adapter is metal and designed to mount securely, but with rings like this, fit quality in real life can depend on the specific lens and how it mates.
What to check before you buy
Before you commit, do a quick thread-size sanity check. The listing is clear about how adapter ring sizing works:
- Verify your lens thread size (46mm) from under the lens cap or on the lens barrel.
- Confirm your accessory is truly 72mm in filter size.
- If you’re using it for filters, double-check the filter’s stated size matches the second number in the adapter.
One more practical point: it’s designed to be removed when not needed, so consider whether you’ll frequently swap between direct-mount filters and larger-diameter accessories.
Compatibility & requirements
The listing says it’s compatible with all 46mm camera lenses and 72mm accessories, and mentions camera brands such as Canon, Nikon, Sony, Fuji, Sigma, and Tamron.
That said, compatibility still hinges on the lens filter thread size. Body brand alone doesn’t always tell the full story—two lenses from the same manufacturer can still have different filter thread sizes.
Final verdict
Is it worth it?
This 46–72mm camera lens adapter is worth considering if you’re trying to use 72mm filters (UV, CPL, ND) or other 72mm front accessories on a 46mm-thread lens without buying multiple filter sets. It’s also a decent “kit organiser” if you want one filter size you stick with across different lenses.
You may want to skip it if you don’t know your lens thread size or if there’s a chance you’ll order the wrong combination—this type of adapter is only useful when the sizes match clearly. If you’re confident on the 46mm lens thread and the 72mm accessory size, it’s a practical value-for-money accessory for everyday shooting.
Mini FAQ
Will this work with different camera brands?
The listing states it’s compatible with lenses from brands like Canon, Nikon, Sony, Fuji, Sigma and Tamron, but the key requirement is still that your lens has a 46mm filter thread.
What does “46–72mm” mean?
It refers to a step-up arrangement: 46mm is the lens thread size, and 72mm is the accessory filter size the ring is intended to accept.
Where can I find my lens thread size?
The thread size should be printed under the lens cap or written somewhere on the lens barrel.
Can I mount filters like UV or CPL straight on this ring?
If the filter size is 72mm, the listing positions it for UV/CPL/ND-style filter use and similar 72mm accessories.
Can I remove it when I don’t need it?
Yes—the adapter is described as designed to fit securely to the lens but still be removable easily when not needed.
