What to Compare Before Buying
- Lens diameter: This version is 40.5 mm. Match the cap size to the front of the lens.
- Included contents: Check that you want the cap, keeper and 2 cloths rather than the cap alone.
- Front-of-lens clearance: The design is stated to work with filters and a lens hood, so compare your lens setup with that arrangement.
- Retention method: The keeper helps hold the cap in place, which is useful if you want to reduce the risk of misplacing it.
What Else You May Need
You need a lens with a 40.5 mm front diameter for this cap size to make sense. If your lens uses a different diameter, choose the matching size instead.
Before You Decide
Confirm the 40.5 mm size, the included keeper and cloths, and whether your lens setup uses filters or a lens hood. If the diameter does not match, this cap will not be the right choice.
