Urth 77mm ND4 2 Stop Double-Threaded Nano-Coating Circular Lens Filter Plus with Ultra-Slim Rim

The Urth ND4 2 Stop Circular Lens Filter Plus provides a fixed 2 f-stop light reduction for better control with long exposure and depth of field techniques in low light. With less light entering your camera, you can also use wider apertures in low light for a beautiful shallow depth of field effect without overexposing images.

Effect

Cinematographers can use the ND4 Filter Plus to create more cinematic effects in low light without losing quality or overexposing the shot.

Feature

The Plus range features 20 layers of nano-coating, providing easier cleaning and better protection against water, oil, and scratches. These layers also provide a higher maximum light transmission and a more consistent transmission curve for truer light reduction.

Better Depth of Field

Beautiful depth of field with wider apertures.

Longer Motion Blur

Cut 2 f-stops for stronger long exposure.

Professional German Glass

Industry-leading German B270 SCHOTT optical glass is coated with a 20-layer nano-coating for truer light transmittance, better protection, and easier cleaning.

Ultra-Slim Rim

Urth's consciously designed ultra-slim rim avoids vignetting, and durable magnalium is guaranteed for life.

Double-Threaded

All the filters are double-threaded for stacking filters or using screw-mount lens caps.

Find Your Filter Size

Inquisitively searching the lens for a diameter symbol often marks the spot. The diameter you seek may be accompanied by the number 77 or 77mm. Look to the side and the front; this precious number is your filter size. Be warned: your lens focal length (e.g., 18 to 55mm) is not your filter size.

Place Flat and Screw Clockwise

Lovingly hold the lens in one hand and place it flat on the lens. Gently screw it clockwise until just firm. Do not over-tighten; what goes on must one day come off.

Slow Your Shutter

The 2-f-stop darkening of your images allows you to slow your shutter speed for motion blur effects.

Open Your Aperture

You can adjust for the 2 f-stop darkening by opening up your aperture, which creates a shallower depth of field. You can also combine both exposure setting adjustments.

Get More Cinematic

Use ND4 to create more cinematic effects when filming. By blocking 2 f-stops of light, you can open your aperture for a shallower depth of field, creating stunning cinematic effects, and slow your shutter for a more cinematic look.
