What is a step up ring

Step up rings, also known as adaptor rings, allow
you to use filters and accessories that are not the
same size as your cameras lens. Lenses and filters
come in a large range of types andsizes and
unfortunately they don't always fit together correctly.
Fortunately there is a step up or step down filter for just about any need.

How step up rings work

Step up rings provide a way to fit a larger diameter filter or accessory onto a smaller lens.

The step up rings screws onto your lenses threading and provided a larger thread with you can then attach other elements included more step up rings.

 

How step down rings work

Step down rings work in the exact same way but instead provide a way to attach smaller accessories and filters to larger lenses.

It is important to note that typically, the farther away from the lens you place a filter the worse the optics will be. It is always best to look for the thinnest adaptor ring that you can find as these will keep the filter close to the lens.
