NEEWER 58-72mm Step Up Ring Adapter (2 stuks) met reinigingsdoek, ultra slanke aluminiumlegering lens filter adapter ring voor 58 mm cameralens te gebruiken 72 mm filter

These work and fit the threads that they should. They are inexpensive and reasonably well-made, with no obvious burrs or similar. There is a bit bit of a tendency of filters mounted on the front, even expensive ones, to get stuck though.They appear to be made of aluminium rather than brass, which is common for cheaper parts like this. This can increase the chance of the thread getting stuck, so you might want to ensure that you keep a thin rubber glove in your camera bag in case you need to remove a filter from the front; this gives you better grip than a bare hand.In any case, reasonable if not amazing for the low price.

Good Quality at a decent price.
