Lens UV Filter walimex Slim Super DMC 49mm – UV protection, slim profile

The walimex Slim Super DMC 49mm ultraviolet (UV) lens filter reduces ultraviolet light transmission and provides front-element protection for compatible 49mm lenses. Its slim profile is designed to minimise vignetting on wide-angle lenses while keeping optical performance intact. The threaded 49mm mount allows straightforward attachment to lenses with the same thread size for everyday, travel and outdoor photography, protecting the front glass from dust, scratches and minor impacts without altering the focal characteristics.

Advantages

The slim aluminium filter frame reduces the risk of corner shading on wide-angle optics and maintains a low overall profile to avoid interference with lens hoods and multipole setups. Multi-coated glass helps to minimise reflections and ghosting, preserving contrast and colour fidelity. The filter combines basic UV attenuation with a protective barrier, allowing photographers to keep the front element safer during routine handling and in exposed environments.

Suitable for

• Everyday and travel photography where front-element protection is needed
• Wide-angle lenses that benefit from a slim filter profile to reduce vignetting
• Outdoor and landscape shooting with variable light conditions
• Photographers seeking to minimise UV haze in daylight conditions

Key specifications

• Filter type: ultraviolet (UV) filter
• Mount diameter: 49 mm threaded
• Frame design: slim profile to reduce vignetting
• Glass treatment: multi-coated to reduce reflections and improve transmission
• Material: aluminium frame with optical glass element

How to use

Align the filter threads with the lens front thread and gently screw the filter clockwise until it seats securely; avoid overtightening to prevent difficulty removing the filter later. Use the filter in place during shooting to protect the front element and to achieve marginal UV reduction in daylight; it can remain mounted while changing shooting angles or focal lengths on compatible lenses. Clean the filter surface with a soft microfiber cloth or lens cleaning solution as needed to maintain image clarity.

Usage recommendations

For wide-angle lenses, check for any vignetting after mounting; the slim profile minimises this risk but testing on your specific lens is advised. Store the filter in a protective pouch when not in use and avoid excessive force when attaching or removing it to preserve the threading and frame alignment.
