Breakthrough Photography X4-CPL-46MM overview

  • 1Description

Filter out polarized light and saturate the skies and foliage in your pictures with the 46mm X4 Brass Circular Polarizer Filter from Breakthrough Photography. This 46mm CPL filter is specially designed to offer a notably neutral performance that avoids color cast and reduces overall exposure by 1 stop, thanks to a rated filter factor of 2x. Two types of coatings are applied: a nano coating that repeals water for easier cleaning, and a multi-resistant coating to reduce reflection and increase the durability of the glass.

Circular polarizers can be used to reduce reflections such as in water and glass windows and work to improve shadow detail in situations with broad dynamic ranges. The X4 CPL marries these effects with a rugged design made for the outdoors, being made of clear Schott B270 glass and a durable brass frame. The sides of the filter are knurled for better grip when adding or removing it from the lens, and a 46mm front thread allows for stacking filters and for the use of optional accessories.

  • 46mm circular polarizer filter, with a 2x filter factor for a 1-stop exposure reduction
  • Helps darken skies, saturate foliage, reduce reflections, and improve shadow detail depending on the situation
  • Designed for color neutral performance, with no yellow cast or spikes near the infrared range
  • Nano coating to repel water and simplify cleaning, and multi-resistant coating to improve durability and image performance
  • Durable Brass frame and Schott B270 glass, with knurled sides for an easier grip
  • 46mm front threads allow for stacking or optional accessories to be used simultaneously with filter

    Breakthrough Photography X4-CPL-46MM reviews

    46mm X4 Brass Circular Polarizer Filter is rated 3.9 out of 5 by 9.
    Rated 2 out of 5 by from Filters always gets stuck Optically the filter is great although even on cameras like my D850 and Hasselblad digital back I am not really seeing a huge difference between this filter and a good B&W one. The biggest difference is the appalling outcome of how often this filter gets stuck on lenses with front diameters that are even a tiny bit larger than the filter is self. There simply is no way to grip the filter because the knurling is really tiny compared to the part that rotates. In my 30+ year career I have never seen a polarizing filter designed this bad in regards to how it physically handles...it’s a nightmare. Right in the middle of a paid ad shoot today I had to send an assistant back to my house some 22 miles away to get a filter wrench so I am totally fed up with it and will literally give it away. Skip this one, it needs to be re-designed.

    Rated 2 out of 5 by from Doesn't allow for lens hood This looked like a good CPL, but I had o return it because it doesn't allow for attachment of the lens hood on a Sony 100-400 GM that has a CPL window. Will have to try another brand. The ridges on the filter would make for nice movement, but are too wide.

    Rated 5 out of 5 by from Excellent CPL This is an exceptional product from materials, construction and performance. The rotating mechanism is the smoothest of any I own including Hoya, B&W, KLM, Heliopan, etc.� The additional gripping serrations are very helpful.� �The filter is free of distortions, and is color accurate.

    Rated 1 out of 5 by from I received a defective and broken product I ordered� the breakthrough 95mm x4 brass CPL and� what I received was a mangled item....completely shattered beyond being useful...this is not acceptable and� the picture below will give you an idea of what I am taking about. I am sure this product was not manufactured this was but unfortunately I am the one receiving a useless item....it's useless and thus I am giving a one star. Will revisit this review when I am able to receive and use a non-malfunctioning product.

    Rated 5 out of 5 by from Worth the investment Go to the their website and read what they offer. The hype is true and I love using this product in the field. I have used several other major brands and used to spend a lot of time removing them when not absolutely necessary. Breakthrough is a product I love to have on my expensive glass and gives me image color I am looking for.

    Rated 5 out of 5 by from Favorite CPL to date So I have tried a lot of CPL's. Even the Lee 100mm system CPL. This is better. The big notches to help rotate are fantastic. I leave this on all the time. The range that the cpl works looks to be a bit wider however you will still get that X darkening like all the others.

    Rated 5 out of 5 by from A fine piece of glass.. This little filter is nothing but quality through and through. Great build, schott glass, knurled edge, made in the USA, and the photographs through the filter are pin sharp..!

    Rated 5 out of 5 by from Great image quality I've used this for a few months now, and haven't had to adjust white balance. Also doesn't degrade image sharpness. Great quality overall!
