Urth 86mm UV Lens Filter

A UV filter blocks ultraviolet light, which can cause haze and a blue cast in outdoor photos, especially at higher altitudes. It also serves as a protective layer for your lens.

Check the lens barrel or cap for a symbol with a line through it and the number '86' (e.g., ø86mm). This indicates the filter thread diameter.

It is most beneficial for outdoor photography, particularly landscapes. For indoor or studio work where UV light is not a factor, its primary benefit is protection.

Yes, you can stack filters, but doing so can potentially reduce image quality (e.g., increased flare, vignetting) and should be done cautiously.

Clean the filter whenever you notice dust or smudges that might affect image quality. Regular cleaning after outdoor shoots is recommended.

This refers to multiple protective and enhancing layers applied to the glass, designed to improve light transmission, reduce reflections, and make the surface resistant to scratches, water, and oil.

Generally, a high-quality UV filter like this has minimal impact on autofocus and exposure. However, in very low light or with certain lens/camera combinations, any filter can introduce minor changes.

Ensure you are using the correct filter size for your lens. If it's still tight, try attaching/detaching without overtightening. Check lens threads for any debris.

Confirm the filter is clean and free of smudges or dust. Ensure it is properly seated on the lens. In extreme lighting conditions, a lens hood may still be necessary.

This filter is designed to *correct* color casts from UV light. If you observe an unwanted cast, ensure the filter is clean and correctly oriented. Recalibrate your camera's white balance if necessary.
