Vivitar 95mm UV Filter

Used this on a telephoto lens for a coastal shoot, and the hard anodized aluminum ring feels solid while the optical glass handled salt spray without any fogging. Light transmission's good enough that I haven't noticed any color shift in the shots.

The multi-coating really cuts down reflections—I shot into a window and the flare was virtually gone. The 90% light transmission keeps my images crisp, and the ring screws on smooth without any binding.

The slim anodized aluminum ring sits perfectly flush against my lens, and the polished optical glass hasn't affected image sharpness at all. It's light and secure, exactly what I needed for protecting the front element.
