FIT CHECK / 01THREAD ØØ 67 MMYou do not need to know camera jargon. Find these three details and we can confirm the rest.
Look for the Ø symbol on the front or inside of your lens cap. Ø67 means you need a 67mm filter.
Tell us what you want to control: reflections, motion blur, light pollution, or lens protection.
List any hood, cap, adapter, matte box, or existing filter that must stay attached.
LENS FRONT / IDENTIFICATIONTHIS IS THE SIZE · Ø77The filter thread size is printed on the front ring of most lenses and usually inside the lens cap. It is always shown with a diameter symbol—not the focal length printed elsewhere on the lens.
Match the technical diagram to what you actually see on your lens and filter stack.
Thread size tells you the physical fit. The stack around it determines whether it stays practical in the field.
| YOUR SETUP | WHAT YOU NEED | RESULT |
|---|---|---|
| 67mm lens + 67mm filter | Nothing | DIRECT FIT |
| 67mm lens + 77mm filter | 67→77 step-up ring | RECOMMENDED |
| 77mm lens + 67mm filter | Step-down ring | RISK OF VIGNETTING |
| Square filter holder | Size-matched adapter ring | SYSTEM FIT |
| Filter + lens hood | Low-profile ring or check | ASK US FIRST |
Keep the thread direction consistent from lens to cap. When in doubt, send a side-on photo of the full stack.
Send a few phone photos and your camera model. You will get a clear answer from the person who runs XT Filters—before you spend anything.
