Olympus Lenses / OM System Lenses Filter Size Chart

Here are the lens diameters and corresponding filter sizes for common Olympus M.Zuiko lenses / OM System M. Zuiko lenses.

I’m focusing here on lenses that accept screw-in filters on the front. (It also applies to lens caps, in most cases.) Some lenses, such as very wide-angle or fisheye lenses, don’t have a filter thread on the front and can’t accept this style of filter. And some very long telephoto lenses use a system of drop-in filters at the rear of the lens.

Some focal lengths have multiple lenses, so it’s important to match the other parts of the name. It’s not uncommon for manufacturers to produce multiple lenses at specific focal lengths, and they don’t necessarily have the same lens diameters.

This is an ongoing list. I’m starting with their current range and adding older lenses to it as the opportunity arises. Please feel free to send through any additions, requests, or corrections.

If you don’t see your lens listed here and want to find out the filter size, it’s often marked on the lens itself. For a more detailed guide, see my post on finding the lens diameter.

A quick way to filter down from this long list is to use the chart’s search bar to narrow it down by focal length (eg. type in “12-40”).
