Gobe if you're willing to correct white balance in post. After recently deciding to buy a CPL for my camera, I whittled the available options down to two -- Gobe 3 Peak (Schott), and Breakthrough Photography X4. On paper, the Gobe has the same specifications as the X4: Schott B270 Glass and 16 layers of coating. The X4 boasts that it's coatings are unlike any other, and that it is able to capture the highest level of sharpness while maintaining perfectly neutral colors. Many comparisons have shown that the X4 is top dog against all the major players. However, I could not find a direct comparison against Gobe and hence decided to give both of them a shot myself. Sharpness: I could not find any significant difference in sharpness between the Gobe and the X4. They are both spot on and do not appear to affect sharpness in the least. Colors: The Gobe definitely shoots "warmer" than the X4. The X4 comes out neutral as advertised. If you seeking out-of-camera accuracy, the X4 wins hands down. However, the Gobe is only SLIGHTLY off, and it can be corrected in a single Spot White Balance click in your post processor of choice. Since most serious photographs will do some amount of post processing anyway, this is not a huge deal. I don't think the average amateur would even notice the difference without a side by side comparison, anyway. Polarization: Both filters were very effective in removing glare in my tests. I could not find a significant difference between the two. Production quality: Both filters are quality products, but the X4 wins here again. The grip portion of the X4 sticks out much further and it easier to screw on and off as a result. The Gobe is much more likely to get stuck on a lens with its design. Extras: The packaging of the X4 was surprisingly hard to open and seems that they tried too hard to make it seem "nice". The amount of jostling that it took to separate the box parts was excessive considering that there is a $160 piece of glass inside it. Gobe on the other hand uses modest packaging and also plants trees with the money they make from their products. Final opinion: The X4 is the better product but, for me, it is not worth the extra $100 that I could instead spend on adding ND filters to my collection. If money is no object or you demand the best, get the X4. If you don't mind a touch of white balance correction and a slightly lesser product in general, get the Gobe. I have included some pictures of my tests. In all pictures, the order is: No filter, Gobe, X4. The car is demonstrating the polarization, and the text is a 100% crop to compare the sharpness. Review: Best Polarizer I've Owned. Should have bought sooner/ - This is a very well-made circular polarizer, covered by a 25-year manufacturer's warranty if you register it online. I've already played with it some, and it functions flawlessly. The markings on the frame make it easy to go from horizontal to vertical framing and quickly switch the filter to the same setting. Maybe someday they'll come out with filters with built-in nanite robots that will automatically adjust the orientation for you, but for now, it is still manual. I would highly recommend any of Breakthrough Photography filters. ## 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 52mm 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. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0186G6PJO | | Best Sellers Rank | #10 in Camera Lens Polarizing Filters | | Brand | Breakthrough Photography | | Coating Description | Nano Coating | | Compatible Camera Models | All camera models with 52mm lens thread | | Compatible Devices | All 52mm camera lenses | | Customer Reviews | 4.5 out of 5 stars 375 Reviews | | EU Spare Part Availability Duration | 25 years | | Enclosure Material | SCHOTT B270 Optical Glass Made in Germany | | Item Dimensions L x W | 2.05"L x 2.05"W | | Manufacturer | Breakthrough Photography | | Manufacturer Part Number | X4-CPL-52mm | | Material | SCHOTT B270 Optical Glass Made in Germany | | Media Type | ProductImage | | Model Name | X4 CPL | | Model Number | X4-CPL-52mm | | Number of Items | 1 | | Photo Filter Effect Type | Polarizer, Ultraviolet | | Photo Filter Size | 5.2 centimeters | | Photo Filter Thread Size | 5.2 centimeters | | Screen Size | 5.2 centimeters | | Set Name | X4 | | Special Effect | Polarizer, Ultraviolet | | Thread Size | 5.2 centimeters | | UPC | 641061423027 | | Unit Count | 1 Count | | Water Resistance Level | Waterproof | ## Product Details - **Brand:** Breakthrough Photography - **Coating Description:** Nano Coating - **Material:** SCHOTT B270 Optical Glass Made in Germany - **Photo Filter Effect Type:** Polarizer, Ultraviolet - **Photo Filter Size:** 52 Millimeters - **Photo Filter Thread Size:** 52 Millimeters - **Product Dimensions:** 2.05"L x 2.05"W - **Set Name:** X4 - **UPC:** 641061423027 - **Water Resistance Level:** Waterproof ## Images ![X4 CPL 52mm Circular Polarizer Filter - Schott B270 - MRC16 - Nano Coating - Weather Sealed - 25 Year Support by Breakthrough Photography - Image 1](https://m.media-amazon.com/images/I/51lWHm-z07L.jpg) ![X4 CPL 52mm Circular Polarizer Filter - Schott B270 - MRC16 - Nano Coating - Weather Sealed - 25 Year Support by Breakthrough Photography - Image 2](https://m.media-amazon.com/images/I/51pgWAHWn3L.jpg) ![X4 CPL 52mm Circular Polarizer Filter - Schott B270 - MRC16 - Nano Coating - Weather Sealed - 25 Year Support by Breakthrough Photography - Image 3](https://m.media-amazon.com/images/I/61CZkT-oExL.jpg) ![X4 CPL 52mm Circular Polarizer Filter - Schott B270 - MRC16 - Nano Coating - Weather Sealed - 25 Year Support by Breakthrough Photography - Image 4](https://m.media-amazon.com/images/I/71z6QNiLH7L.jpg) ![X4 CPL 52mm Circular Polarizer Filter - Schott B270 - MRC16 - Nano Coating - Weather Sealed - 25 Year Support by Breakthrough Photography - Image 5](https://m.media-amazon.com/images/I/61RLIDnXsVL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Gobe 3 Peak (Schott) vs Breakthrough Photography X4 *by T***C on January 1, 2018* TL;DR: X4 if you have the money or NEED the best.

It’s so good you don’t see any downside. *by S***D on February 17, 2025* Great polarizer! (For those who thinks it doesn’t work, it doesn’t reduce light as much as cheaper ones, so it *appears* to be “not working”. Try standing in front of a mirror with the polarizer and flip it around a few times and you will see in the mirror that it is blocking light just fine.) Like other polarizers, it is quite thin, and not trivial to get back off your lens unless you use a rubber band around it to get a good grip. Before you say it, yes, I agree, they should provide that with the filter (and probably with GND filters too). Check the results with and without the polarizer in water, sun at a cross-angle to you, snow, and so on. You will be very pleased with the results! ## Frequently Bought Together - X4 CPL 52mm Circular Polarizer Filter - Schott B270 - MRC16 - Nano Coating - Weather Sealed - 25 Year Support by Breakthrough Photography - SanDisk 128GB Extreme PRO SDXC UHS-I Memory Card - C10, U3, V30, 4K UHD, SD Card - SDSDXXD-128G-GN4IN --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/65632185-x4-cpl-52mm-circular-polarizer-filter-schott-b270-mrc16-nano](https://www.desertcart.pt/products/65632185-x4-cpl-52mm-circular-polarizer-filter-schott-b270-mrc16-nano) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-09-18*
