105mm to 82mm lens adapter ring

Key features

If you have a 105mm lens but want to use common 82mm filter accessories, this 105mm to 82mm camera lens adapter ring is a straightforward fix. The adapter screws onto the front of a 105mm lens and converts the thread size so you can attach 82mm filter, hood and other threaded accessories. It can help you avoid the hassle of buying separate filter sizes when you already own gear that uses 82mm threads.

The adapter is made from high quality aluminium alloy, with a glossy finish and a corrosion resistant build. According to the manufacturer, it is produced using ultra precision CNC machine tools and is designed to offer good operation stability. That matters when you repeatedly attach and remove filters, lens hoods or converters in day to day shooting, because a solid, stable fit reduces the chance of awkward handling. 😀

There is also a practical size guidance you can use before ordering. The ring adapts 105mm lens threads down to 82mm accessory threads, and the manufacturer notes that the first number refers to the lens thread size, while the second number refers to the accessory thread size. Keep in mind that this is a step down ring, so you want 105 to 82, not the reverse. 🙂

What stands out

One of the biggest advantages here is thread size conversion. If your lens has a Ø105mm thread and your filter or accessory uses Ø82mm threads, the adapter bridges that difference so everything can screw together neatly. The manufacturer also points out that the lens thread size is usually printed under the lens cap or written on the lens barrel, often prefixed with an O diameter symbol such as Ø105mm.

This is also a useful option if you already own multiple 82mm accessories, like UV, CPL or ND filters, and you want to swap them between lenses without replacing every filter. Once mounted, the adapter provides the correct thread size for those 82mm accessories so you can focus on shooting rather than shopping for matching sizes. 👍

It is worth noting that thread sizing errors are the most common reason adapters do not fit. The manufacturer specifically warns to order the correct direction, because 82-105mm is not the same as a 105-82mm step down ring. If you are between sizes, it is safest to double check the exact thread number on your lens before you buy. 📷

Where it shines

It makes sense if your main lens is a 105mm threaded camera lens, but your filters, lens hoods or other accessories are all 82mm. It suits everyday situations where you want predictable compatibility, for example when switching from a UV filter to a CPL filter or adding an ND filter for changing light. You’ll like it if you frequently use threaded lens accessories and prefer a simple screw-on method over other mounting systems.

It may not suit you if your lens thread size is not Ø105mm, or if your accessories are not actually sized for Ø82mm threads. It might not be a great match if you are trying to do the opposite conversion direction, because this is a step down setup from 105mm to 82mm. It also depends on verifying that the thread number on your lens is the one you need, as the manufacturer notes that ordering the wrong size means it will not fit.
