Designed for the IP-A Filter Holder for the iPhone, the True Color ND-VARIO Pro Nano 1-5 Stop Variable ND Filter from NiSi provides a 1 to 5-stop reduction in exposure, allowing the use of wider aperture settings for shallow depth of field or slower shutter speeds for motion blur. The variable exposure control is set using a filter ring with hard stops at each end. Thanks to True Color technology, this filter avoids color shifts often seen in other variable ND filters.

This filter is built using high-definition optical glass with nano and antireflective coatings. It is also waterproof and may be stacked for use with other filters.

Q: 1. Hi. Can this filter be used on a Leica 50mm APO-Summicron-M ASPH f/2.0 lens? Thank you.

A: The lens has a 39mm filter thread. This filter would not be compatible. B+W makes the same filter in 52mm. If you use a 39-52mm step up ring, then you will be able to use this filter on the Leica lens.Here is the step up ring: http://bhpho.to/1u0UKvfHere is the filter: http://bhpho.to/1qoJGa9

Q: 2. Is the adapter still for 52mm filters and if not what size circular filters?

A: The NiSi IP-A Filter Holder for iPhone BH #NISIIPA would use a 43mm size filter.

Q: 3. What is the filter thickness?

A: As per NiSI, the 49mm True Color Pro Nano Circular Polarizing Filter is about 5mm thick not including the threads. However, when factoring in the threads, it would be just under 8mm thick.

Q: 4. Has anyone used this filter on the new Canon RF100-300mm zoom lens?

A: Yes, you can connect NiSi 112mm True Color Pro Nano Circular Polarizing Filter for Nikon Z 14-24mm f/2.8 S Lens to the 112mm front thread accesory on the Canon RF 100-300mm f/2.8 L IS USM Lens (Canon RF).

Q: 5. Does this filter have hard stops?

A: So as not to confuse with my prior answer, there are no intermediate stops but yes there are stops at each end.

Q: 6. How does this compare to NiSi Ti Enhanced Landscape filter? Which is better for Tamron 17-28mm f2.8 lens?

A: While both the NiSi Ti Enhanced Landscape filter and the NiSi 82mm True Color Pro Nano Circular Polarizing Filter are appropriate circular polarizers for the Tamron 17-28mm f/2.8, there are some feature based differences. The NiSi 82mm True Color Pro Nano Circular Polarizing Filter offers a knurled ring for easier grip, but is comprised of aluminum compared to the NiSi 82mm Ti Enhanced Landscape Circular Polarizer Filter which has a titanium frame, but lacks the knurled ring.

Q: 7. Is that adapter for 58mm filters?

A: No, the NiSi IP-A Filter Holder for iPhone BH #NISIIPA does not support 58mm filters.

Q: 8. Does this really fit directly on the Z 14-24? 112 mm seems too large for that to work!

A: Nikon NIKKOR Z 14-24mm f/2.8 S Lens includes the Nikon HB-97 Lens Hood in the box. This lens hood has a 112mm thread which allow filters like NiSi 112mm True Color Pro Nano Circular Polarizing Filter for Nikon Z 14-24mm f/2.8 S Lens to be screw on directly on the lens.

Q: 9. Will this NiSi CPL TRU-color 72mm filter show vignetting while it is on the Sony 20-70mm f4 type 2 lens at 20mm ?

A: The NiSi 72mm True Color Pro Nano Circular Polarizing Filter is very thin. But has not been tested with the Sony 20-70mm f/4 lens. Chances are it will be if any very little vignette at 20mm.

Q: 10. What kind of packaging is this filter sent in?

A: The NiSi 72mm True Color Pro Nano Circular Polarizing Filter is sent in a carboard box that holds a thick plastic case with a foam insert to keep it from shifting.
