Product Information
Full details
The Urth 77mm CPL Lens Filter Pro is designed for professional photographers and serious enthusiasts who demand elite optical clarity and precise light control. By utilizing premium SCHOTT B270 glass and an advanced 34-layer nano-coating, this filter effectively eliminates 99.9% of polarized light, significantly reducing glare from water and glass while boosting color saturation. While it offers superior build quality and ease of use, users should note that the high-density multi-coating requires careful cleaning to avoid smearing, and the slim frame design may be slightly more difficult to attach to lenses with very recessed front elements.

FAQs
Will this filter cause vignetting on my wide-angle lens?
The filter features a slim-profile frame specifically designed to minimize the risk of vignetting, even on most wide-angle lenses.
Can I leave this filter on my lens all the time?
Yes, it can serve as a permanent protective element, though keep in mind it will reduce light intake by about 1.5 to 2 stops.
Is the Urth CPL compatible with lens hoods?
Yes, the filter is designed to be low-profile enough to work with most standard lens hoods, though it may be tighter to attach.
What happens if the filter gets wet?
The nano-coating is water-repellent, causing water to bead up and roll off, which makes it easy to wipe away with a cloth.
Does this filter affect autofocus speed?
No, the high-quality optical glass ensures that light transmission remains high, having no negative impact on modern camera autofocus systems.
Troubleshooting
Difficulty removing the filter from the lens
Use a specialized rubber filter wrench to apply even pressure to the frame, or place a thick rubber band around the rim for extra grip.
Visible smudges or streaks on the glass
Use a fresh, clean microfiber cloth and ensure the lens surface is completely dry before wiping to prevent dragging debris across the coating.
Polarization effect does not change when rotating
Verify that you are rotating the front ring of the filter, not the entire filter assembly that is attached to the lens.

Setup, Compatibility & Care
To install, gently thread the 77mm filter clockwise onto the front of your lens filter threads until snug. Do not overtighten, as the aluminium threads can bind. For compatibility, this filter fits any lens with a 77mm filter thread diameter.
For care, always use a dedicated lens blower first to remove loose dust particles before wiping the glass. Use a high-quality microfiber cloth for cleaning, and if necessary, use a small amount of non-abrasive optical cleaning fluid. Always store the filter in the provided protective case when not in use to avoid accidental scratches on the nano-coated surface.
