This 39mm Urth ND Lens Filter 39mm 4-Stop Plus+from Urth ND Lens Filter 39mm 4-Stop Plus+provides a fixed 4-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 shallower depth of field effect without overexposing images. Cinematographers can use the ND16 Filter Plus+ to create more cinematic effects in low light without losing quality or overexposing the shot. 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.

1.2 Optical Density    20-Layer Nano-Coating    B270 Schott Optical Glass    Ultra-Slim Rim    Double-Threaded for Stacking Filters

The fixed ND16 Filter Plus+ lets you capture motion blur and depth of field effects in low light. It is great for landscape photography and cinematic effects in videography.

Reduce light to 6.25% to maintain you desired settings in overly bright conditions or create dramatic motion blur and shallow depth of field in low light conditions.

The filter is double-threaded for stacking filters or using screw-mount lens caps.

The B270 Schott optical glass is coated with a 20-layer nano-coating for truer light transmittance, better protection, and easier cleaning.

The consciously designed ultra-slim rim avoids vignetting and our durable magnalium is guaranteed for life.

Related Questions and Answers

Q: 1. Is this filter ISO certfied?

A: If by ISO certified, you mean is it certified for visual (eyeball) use - not to my knowledge. This filter is intended for photo use only. For visual observation, use a filter intended for direct visual observation of the sun. I'm using the Hoya filter on a Canon PowerShot SX50 for taking photos of the uneclipsed or partially eclipsed sun using the LCD viewfinder. Don't use the optical viewfinder! Safe visual solar filters are readily available and cheap.

Q: 2. Do these have stops at min/max?

A: According to Urth, the Plus+ ND filters have hard stops at maximum and minimum stops.

Q: 3. Does this fit a Leica E39 lens?

A: Yes this fits Leica E39 Lenses.

Q: 5. Can you stack this filter with a CPL?

A: There are no front filter threads for attaching a filter to the front of the NiSi ND64 112mm NC Neutral Density Filter for Nikon Z 14-24mm f/2.8 S Lens (6-Stop) (B&H# NICCN64NZ). As such, you would have to add this on top of the CPL or other filter to use them together.

Q: 6. Is this compatible with the 24mm Gmaster 1.4 lens?

Q: 7. Is it possible to use a lens cap with the filter?

A: Yes, the Urth UV + Circular Polarizing (CPL) Lens Filter Kit (82mm) has standard 82mm front threads for use with a standard 82mm lens cap.

Q: 8. Will this filter work in the Lee Holder?

A: The filters I use fit in the Cokin Size P holder - that is 84mmx120mm - there are several sizes available so be aware of the sizes. Also stacking these neutral density filters can add a slight magenta hue to color images - that is due to the new environmentally friendly chemicals used in the dyeing process. This is something that can be corrected in post processing

Q: 9. Will this Filter thread onto a regular 82mm-122mm step-up ring? Eg. BH #HYELA82112 • MFR #ELA82-112.

Q: 10. Is it specifics fin Nikon Zmount
