The questions we hear daily.
Orders typically process in 1–3 business days and ship from China by USPS / Royal Mail. Transit is 5–7 business days. Standard shipping is $8, free on orders over $99. Customs clearance can add time. Read the shipping policy.
Customs duties and import fees depend on your destination. Review the destination-specific duty notice shown on product and checkout pages, or contact us before ordering for confirmation. Read the shipping policy.
Every XT filter is packed in a shockproof hard case and reinforced box. If your filter arrives cracked, chipped, or damaged in transit, or is lost by the carrier, email Leo (info@xtfilters.com) with a photo. We will immediately dispatch a brand-new replacement at zero cost — no return of broken glass required. Read transit guarantee.
The 1-year warranty covers manufacturing defects. It does not cover drops, shattered glass, or scratches from grit. Email Leo your order number and clear photos. Read the warranty policy.
No. Filters must match your lens thread size exactly. If you already own a 67→77mm step-up ring, it lets you use a larger filter on a smaller lens. We sell the filters, not the rings. Check the front of your lens or your lens manual for the correct thread size.
Yes. If a filter arrives defective, email Leo within 30 days of delivery with your order number and clear photos. Change-of-mind and wrong-size orders are not defect returns. Confirm the Ø mark before you order, or ask Leo first. Read the refund policy.
Clear protection and the L39 UV are meant to leave the picture alone. Compare one frame if you want to check. A CPL and a Black Mist change the picture on purpose: reflections drop, or highlights get softer.
Contact us as soon as possible with your order number. If your order has not shipped yet, we will do our best to change or cancel it.
Use a blower or soft brush first, then a clean microfiber lens cloth. For smudges, breathe lightly on the glass or use a small amount of lens cleaning solution on the cloth. Never pour liquid directly on the filter.
Email Leo before ordering and include the details of your request. Any currently available discount will be confirmed personally.
