BREAKTHROUGH FILTERS X4 ND

At last……..the world’s most colour neutral ND filter range is back in stock in the UK.

Breakthrough filters has become a force to be reckoned within the US photographic world.
So what has led to this meteoric rise of Breakthrough Filters in the USA?

The X4 ND achieves a higher optical resolution than any other ND filter, and thanks to our state-of-the-art and uniformly applied MRC16 and nanotec® nano coating layers, the X4 ND lives up to the demands of the professional outdoor photographer and any photographer who doesn't want a colour cast in their captured image.

Tech Specs for the X4 ND Filters

3.1mm SCHOTT Ultrawhite B270 optical German Glass

Definitely the best glass. Some competitors do use it but seldom at 3.1mm.

                                     Weather-sealed

Built to withstand extreme wind, salt water, dust and other abrasive conditions and elements. Weather-sealing should be an integral part of design in any landscape photographic equipment!

Nanotec

Nano coating layers that repels dirt, water and other elements by beading rather than absorbing, making it easier and faster than ever to clean. Obviously we feel sure our own nano coating (Nanotec) is better than others but some competitors do have nano coating.

                  Tracking Frame

This should be another integral part of design for any filter, especially if being used outside in all weathers and often extreme conditions. Fingers become numb, metal contracts and the simplest of actions become harder, like taking a filter on or off. A tracking frame enables far better purchase to turn a filter without excessive force. A few other brands do have this… I wonder where they got the idea from!

           16 MRC Layers

This technical specification is often quoted for filters. These layers increase the light transmission and can also, in the case of our MRC layers, create a protective layer that’s structurally harder than the glass! The crucial factor here though is the light transmission .....

So whilst we are confident the above market leading design features put Breakthrough Filters up there, some of our competitors do have some of these design features. So why are we ahead of the curve?

The Tech Team Get A New Toy!

When using an ND filter you want to reduce the light transmission so why coat them? True, an ND filter reduces the light going through the lens and hitting the sensor enabling longer exposures. What is extremely important is to reduce any colour cast so the light needs to be transmitted with maximum reduction in reflections and distorting scattered light. This is most effectively done with coating both sides of the glass NOT one side which, whilst cheaper to produce, increases the scattering. There are competitors who give their filters 16 MRC layers, a few on both sides too. So we wanted to be absolutely sure we were the best. It was time to get the tech team a new toy…..a spectrometer and the results are below.

Light transmission chart showing comparisons of 10-Stop ND filters for 400-700 nm (visible spectrum of light) . 
From the chart we can see that the Singh-Ray has marginally better light transmission. However it's cost point is significantly higher. Next chart looks as the light transmission across the visible spectrum.

What all filter manufacturers should be after is the flattest curve as close to 0.10% as possible. The flatter the curve, the closer to 0.10% the less colour caste there will be across the whole visible spectrum.

The Breakthrough X4 ND performance is clear with the Singh-Ray a close second.
