## Overview

The Breakthrough Photography X4 CPL 72mm Circular Polarizer Filter features premium Schott B270 optical glass combined with advanced MRC16 and Nano coatings for superior clarity, color neutrality, and durability. Weather-sealed and backed by a 25-year guarantee, it’s engineered for professional photographers seeking flawless polarization without color cast or sharpness loss.

## Description

The X4 CPL features SCHOTT Superwhite B270 optical glass, which is an ultra clear crown glass. It is produced by melting high purity raw materials and then made using the continuous draw process. The result is excellent transmission in the ultraviolet, visible, and infrared spectrums, and a high surface quality that accepts our state-of-the-art MRC and nanotec coatings exceptionally well.

Review: I usually go with B+W when it comes to filters but I decided to try Breakthrough after hearing about them recently and I’m sold on this brand. Everything including the packaging is top notch. The CPL filter doesn’t impart any weird hues to your image and I really like how it has the highest light transference in industry. I believe you only lose 1 stop of light vs 1.5-2 on others. As an everyday filter this is excellent. I shot a few test images this weekend and on my a7CR there is no visible sharpness impact and colors and contrast look incredible. Will be ordering their ND as well next.
Review: I have purchased Breakthrough Photography products in the 82mm, 77mm and 72 mm filter range (CPL, Dark CPL, and Neutral Density). I think the product is high quality. I am a Nikon guy and almost exclusively purchase Nikon products. Also, all my lens wear a Nikon NC filter. My choice to keep the NC filter clean and minimize touching the much more expensive lens. I am currently on a 5.5 month trip to the Philippines and Thailand and thought I would bring along various Breakthrough Photography filters and see if I noticed a difference from my Nikon filters. Equally important, to my knowledge Nikon does not offer the 'dark CPL' type filter. My experience: excellent filter, easy to clean and does the job it is supposed to do. When compared to similar Nikon products I do not see a major difference but (to be fair), I am only looking at my photos on my MacBookPro so I will not be able to do take a better look at comparisons until I return to the USA. What I do NOT like: the Breakthrough filters get 'bind' to my Nikon NC filter. I can NOT unbind them. I have tried filter clamps (a waste of money and time). I have removed the 'set' and used as much force as I dared to try. What has worked for this ridiculous situation. I leave the bound filters in the sunlight in my hotel room window for a while. Most of the time once the filters have heated up I can pry them apart (by unscrewing them). But out in the field I have never been able to get them apart. My next strategy is the because of this problem I place another Nikon NC filter on my lens (I have spares). I then just let the two filters that are 'stuck' to each stay stuck to each other. When I do not need a CPL type filter I just remove both the filters and replace it with a single Nikon NC filter. This situation is annoying but I do have a work around. I have also tried to 'loosely' connect the CPL lens -- this approach does not work. When I have adjusting the CPL directivity the entire filter also turns. And given the significant cost of the Breakthrough filters I do not trust that it won't just fall off and break at some point. Recommendation: I do like these Breakthrough Photography filters. I wish the engineering staff did a better job of periodically placing some type of minor extensions along the gripping part (knurled edges) of the lens so you can actually get a grip on the d@mn filter to apply some torque to remove it. This is probably a problem in itself due to placing lens hood. An alternative is to provide an actual grip device (like a filter clamp) that is specifically designed for this product line. An OEM provided tool (should hopefully have) gone through quality control such that it 'perfectly' fits the Breakthrough Photography knurled edges.

## Features

- WORLDS MOST COLOR NEUTRAL POLARIZER, GUARANTEED: A perfectly flat transmission curve would yield a perfectly color neutral result, and while there is no such thing as a perfectly neutral CPL filter (contrary to what other filter makers may claim) the X4 CPL is the most color neutral any CPL filter, guaranteed.
- WORLDS MOST ADVANCED POLARIZER: All commercially available CPL filters exhibit a yellow cast due to a gradual transmission increase starting around 600nm and then spiking at 650nm onward into IR. With our X4 CPL film we achieved a gradual transmission decrease from 600nm onward, and instead of spiking uncontrollably near 650nm and far into infrared, the X4 CPL sees very controlled transmission into IR, without the curve spike. Result: Warm and lively images without the apparent colorcast.
- X4 CPL (CIRCULAR POLARIZER) FILTER: The X4 CPL features SCHOTT Superwhite B270(R) optical glass, which is an ultra clear crown glass. It is produced by melting high purity raw materials and then made using the continuous draw process. The result is excellent transmission in the ultraviolet, visible, and infrared spectrums, and a high surface quality that accepts our state-of-the-art MRC and nanotec(R) coatings exceptionally well.
- FITMENT: This CPL filter is compatible with all 72mm camera lenses. Your lens thread size will be printed underneath your lens cap or written somewhere on the lens barrel. Make sure you order the correct size otherwise it will not fit your lens.
- 25 YEARS SUPPORT: We stand behind every CPL filter we make with our 25 Year Ironclad Guarantee. Every X4 CPL filter has a unique serial number laser engraved onto the interior frame. When you activate your 25 Year Ironclad Guarantee, we assign this serial number to you, so any future discussions on this unique filter are tracked, issues recorded and all that stuff which goes into future product design.

Quality filter. No problems with the threads. Made of brass, so very sturdy.
