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 and
sizes 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 screw onto your lense’s threading and provide a larger thread to which you can then attach other elements including 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.
