Objective cover 57 mm, Focus Sport Optics, 2 pcs

Set of two objective covers designed for optical equipment with a 57 mm objective diameter. These Focus Sport Optics covers protect front lenses from dust, scratches and moisture when optics are not in use. The covers are intended for instruments such as binoculars, spotting scopes or telephoto lenses that have a 57 mm front thread or outer diameter, offering basic physical protection during storage and transport.

Advantages

Made to fit a 57 mm objective size, the covers provide a secure and low-profile barrier that helps reduce the risk of surface damage and contamination. They are quick to attach and remove, allowing fast access to optics without risking contact with the lens. The two-piece set ensures both optical elements are protected simultaneously and is compact for convenient storage in carrying cases or packs.

Suitable for

• Binoculars with 57 mm objective diameter
• Spotting scopes with 57 mm front thread or outer diameter
• Telephoto lenses and camera lenses with 57 mm front thread or outer diameter
• Storage and transport of outdoor optics

Key specifications

• Quantity: 2 covers
• Intended objective diameter: 57 mm
• Protection: dust, scratches and light moisture protection
• Attachment: simple slip-on or thread-compatible fit for 57 mm front
• Material: durable protective material suitable for external lens surfaces

How to use

Align each cover with the objective lens edge and push gently until the cover seats securely. If the optical instrument has a front thread matching 57 mm, turn or press the cover to achieve a snug fit according to the design. To remove, grip the cover and pull or twist off carefully to avoid contact with the lens surface. Clean covers with a soft cloth and mild detergent if necessary, and ensure lenses are dry before fitting.

Usage recommendations

Use the covers whenever optics are stored or transported to minimize dust and mechanical wear. Do not rely on these covers for long-term waterproofing or impact protection; combine with a padded case for improved protection during travel. Inspect covers periodically for wear and replace if deformation reduces fit.
