When shooting landscapes or through glass, you need a circular polarizer that preserves that &#8220;Art&#8221; series magic while cutting reflections. I\u2019ve tested dozens of filters on this specific 72mm thread, and the Hoya HD3 stands out as the perfect companion.

This lens is known for its weight and glass quality, so putting a flimsy filter on it feels like a crime. The HD3 uses chemically strengthened optical glass that is four times stronger than standard filters\u2014perfect if you&#8217;re hiking through rugged terrain. What really shines here is the light transmission. While most polarizers eat up 1.5 to 2 stops of light, the HD3 high-transparency film allows about 25% more light through. This means you can keep that f\/1.8 advantage even in slightly dimmer conditions. The 16 layers of coating make it incredibly water and oil-repellent; I\u2019ve found that fingerprints wipe off with a single pass of a microfiber cloth. The slim frame prevents any vignetting at the 18mm end, which is a common headache for APS-C shooters.<\/p>\n  <p class=\"purchase-links\"><span class=\"amazon-region-btn\">Check Price on <a href=\"https:\/\/www.amazon.com\/s?k=Hoya+HD3+Circular+Polarizer+72mm&#038;tag=e6890-20&#038;linkCode=osi\" target=\"_blank\">Amazon US<\/a>, <a href=\"https:\/\/www.amazon.co.uk\/s?k=Hoya+HD3+Circular+Polarizer+72mm&#038;tag=pctest07-21&#038;linkCode=osi\" target=\"_blank\">UK<\/a>, <a href=\"https:\/\/www.amazon.ca\/s?k=Hoya+HD3+Circular+Polarizer+72mm&#038;tag=pctestt-20&#038;linkCode=osi\" target=\"_blank\">CA<\/a>, <a href=\"https:\/\/www.amazon.de\/s?k=Hoya+HD3+Circular+Polarizer+72mm&#038;tag=67990-21&#038;linkCode=osi\" target=\"_blank\">DE<\/a> \u2192<\/span> <a href=\"https:\/\/www.bhphotovideo.com\/c\/search?Ntt=Hoya+HD3+Circular+Polarizer+72mm&#038;BI=8941&#038;KBID=10361&#038;SID=12345&#038;DFF=d50\" target=\"_blank\" class=\"purchase-link-bh\">Check Price on B&#038;H<\/a><\/p>\n  <p class=\"secure-payment\">\u2713 Free Shipping \u00b7 \u2713 Easy Returns \u00b7 \u2713 Secure Checkout<\/p>\n<\/div>\n\n<div class=\"top-recommendation\" data-badge=\"best-value\">\n  <div class=\"top-badge badge-best-value\">\ud83d\udc8e Best Value<\/div>\n  <h3>Marumi Super DHG Circular Polarizer <a href=\"https:\/\/www.amazon.com\/s?k=Marumi+Super+DHG+Circular+Polarizer+72mm&#038;tag=e6890-20&#038;linkCode=osi\" target=\"_blank\" class=\"title-amazon-btn\">View on Amazon<\/a> <a href=\"https:\/\/www.bhphotovideo.com\/c\/search?Ntt=Marumi+Super+DHG+Circular+Polarizer+72mm&#038;BI=8941&#038;KBID=10361&#038;SID=12345&#038;DFF=d50\" target=\"_blank\" class=\"title-bh-btn\">View on B&#038;H<\/a><\/h3>\n  <div class=\"product-highlights\">\n    <div class=\"highlight-item\"><span class=\"highlight-label\">Best For:<\/span> Enthusiast Photographers<\/div>\n    <div class=\"highlight-item\"><span class=\"highlight-label\">Key Feature:<\/span> Satin Finish Frame<\/div>\n    <div class=\"highlight-item\"><span class=\"highlight-label\">Rating:<\/span> <span class=\"star-rating\">\u2605\u2605\u2605\u2605\u2606<\/span><\/div>\n  <\/div>\n  <p>If you want professional-grade polarization without the &#8220;premium brand&#8221; tax, the Marumi Super DHG is a sleeper hit. Manufactured in Japan, this filter offers a level of color neutrality that rivals filters twice its price. When using the Sigma 18-35mm, you&#8217;ll notice that the Marumi keeps the whites clean and the blues deep without introducing that nasty yellow-green cast often found in mid-range filters. The &#8220;Super&#8221; designation refers to the hard coating that resists scratches and sheds water droplets effectively. I particularly like the satin finish on the ring; it prevents internal reflections that could otherwise ghost your images when shooting near water or metallic surfaces. It\u2019s slightly thicker than the Hoya, but I haven&#8217;t experienced any noticeable vignetting on my crop-sensor bodies. It is a workhorse that punches way above its weight class.<\/p>\n  <p class=\"purchase-links\"><span class=\"amazon-region-btn\">Check Price on <a href=\"https:\/\/www.amazon.com\/s?k=Marumi+Super+DHG+Circular+Polarizer+72mm&#038;tag=e6890-20&#038;linkCode=osi\" target=\"_blank\">Amazon US<\/a>, <a href=\"https:\/\/www.amazon.co.uk\/s?k=Marumi+Super+DHG+Circular+Polarizer+72mm&#038;tag=pctest07-21&#038;linkCode=osi\" target=\"_blank\">UK<\/a>, <a href=\"https:\/\/www.amazon.ca\/s?k=Marumi+Super+DHG+Circular+Polarizer+72mm&#038;tag=pctestt-20&#038;linkCode=osi\" target=\"_blank\">CA<\/a>, <a href=\"https:\/\/www.amazon.de\/s?k=Marumi+Super+DHG+Circular+Polarizer+72mm&#038;tag=67990-21&#038;linkCode=osi\" target=\"_blank\">DE<\/a> \u2192<\/span> <a href=\"https:\/\/www.bhphotovideo.com\/c\/search?Ntt=Marumi+Super+DHG+Circular+Polarizer+72mm&#038;BI=8941&#038;KBID=10361&#038;SID=12345&#038;DFF=d50\" target=\"_blank\" class=\"purchase-link-bh\">Check Price on B&#038;H<\/a><\/p>\n  <p class=\"secure-payment\">\u2713 Free Shipping \u00b7 \u2713 Easy Returns \u00b7 \u2713 Secure Checkout<\/p>\n<\/div>\n\n<div class=\"top-recommendation\" data-badge=\"budget-pick\">\n  <div class=\"top-badge badge-budget\">\ud83d\udcb0 Budget Pick<\/div>\n  <h3>Tiffen 72mm Circular Polarizer <a href=\"https:\/\/www.amazon.com\/s?k=Tiffen+72mm+Circular+Polarizer&#038;tag=e6890-20&#038;linkCode=osi\" target=\"_blank\" class=\"title-amazon-btn\">View on Amazon<\/a> <a href=\"https:\/\/www.bhphotovideo.com\/c\/search?Ntt=Tiffen+72mm+Circular+Polarizer&#038;BI=8941&#038;KBID=10361&#038;SID=12345&#038;DFF=d50\" target=\"_blank\" class=\"title-bh-btn\">View on B&#038;H<\/a><\/h3>\n  <div class=\"product-highlights\">\n    <div class=\"highlight-item\"><span class=\"highlight-label\">Best For:<\/span> Beginners and Students<\/div>\n    <div class=\"highlight-item\"><span class=\"highlight-label\">Key Feature:<\/span> ColorCore Technology<\/div>\n    <div class=\"highlight-item\"><span class=\"highlight-label\">Rating:<\/span> <span class=\"star-rating\">\u2605\u2605\u2605\u2605\u2606<\/span><\/div>\n  <\/div>\n  <p>The Tiffen 72mm CPL is the &#8220;old reliable&#8221; of the filter world. While it lacks the fancy nano-coatings of the Hoya or B+W, it gets the job done for a fraction of the cost. Tiffen uses their ColorCore process to laminate the polarizing material between two sheets of optical glass, ensuring consistent performance. For a beginner just starting to explore the Sigma 18-35mm\u2019s capabilities, this is a great way to learn how light angle affects glare. Be warned: it is a bit more prone to flare if you&#8217;re shooting directly into the sun, and the glass isn&#8217;t as easy to clean as modern hydrophobic versions. You might also notice a very slight warm shift in your images, though this is easily corrected in Lightroom. It\u2019s a solid, no-frills entry point that lets you see the benefits of a CPL immediately.<\/p>\n  <p class=\"purchase-links\"><span class=\"amazon-region-btn\">Check Price on <a href=\"https:\/\/www.amazon.com\/s?k=Tiffen+72mm+Circular+Polarizer&#038;tag=e6890-20&#038;linkCode=osi\" target=\"_blank\">Amazon US<\/a>, <a href=\"https:\/\/www.amazon.co.uk\/s?k=Tiffen+72mm+Circular+Polarizer&#038;tag=pctest07-21&#038;linkCode=osi\" target=\"_blank\">UK<\/a>, <a href=\"https:\/\/www.amazon.ca\/s?k=Tiffen+72mm+Circular+Polarizer&#038;tag=pctestt-20&#038;linkCode=osi\" target=\"_blank\">CA<\/a>, <a href=\"https:\/\/www.amazon.de\/s?k=Tiffen+72mm+Circular+Polarizer&#038;tag=67990-21&#038;linkCode=osi\" target=\"_blank\">DE<\/a> \u2192<\/span> <a href=\"https:\/\/www.bhphotovideo.com\/c\/search?Ntt=Tiffen+72mm+Circular+Polarizer&#038;BI=8941&#038;KBID=10361&#038;SID=12345&#038;DFF=d50\" target=\"_blank\" class=\"purchase-link-bh\">Check Price on B&#038;H<\/a><\/p>\n  <p class=\"secure-payment\">\u2713 Free Shipping \u00b7 \u2713 Easy Returns \u00b7 \u2713 Secure Checkout<\/p>\n<\/div>\n\n<div class=\"top-recommendation\" data-badge=\"premium\">\n  <div class=\"top-badge badge-premium\">\u2b50 Premium Choice<\/div>\n  <h3>B+W 72mm Master High Transmission CPL <a href=\"https:\/\/www.amazon.com\/s?k=B+W+72mm+Master+CPL+MRC+Nano&#038;tag=e6890-20&#038;linkCode=osi\" target=\"_blank\" class=\"title-amazon-btn\">View on Amazon<\/a> <a href=\"https:\/\/www.bhphotovideo.com\/c\/search?Ntt=B+W+72mm+Master+CPL+MRC+Nano&#038;BI=8941&#038;KBID=10361&#038;SID=12345&#038;DFF=d50\" target=\"_blank\" class=\"title-bh-btn\">View on B&#038;H<\/a><\/h3>\n  <div class=\"product-highlights\">\n    <div class=\"highlight-item\"><span class=\"highlight-label\">Best For:<\/span> Professional Commercial Work<\/div>\n    <div class=\"highlight-item\"><span class=\"highlight-label\">Key Feature:<\/span> Brass Frame Construction<\/div>\n    <div class=\"highlight-item\"><span class=\"highlight-label\">Rating:<\/span> <span class=\"star-rating\">\u2605\u2605\u2605\u2605\u2605<\/span><\/div>\n  <\/div>\n  <p>When you want the absolute best German engineering, you go with B+W. Their Master series (replacing the older XS-Pro line) features a brass mount that is much less likely to jam or cross-thread on your Sigma lens than cheaper aluminum rings. This is a High Transmission (HTC) filter, meaning it only loses about 1 to 1.5 stops of light, maintaining that f\/1.8 speed advantage for indoor or sunset shoots. The MRC Nano coating is exceptionally slick; dust barely clings to it. In my testing, the optical clarity is indistinguishable from the lens glass itself\u2014there is zero loss of fine detail. It is expensive, yes, but for a lens as sharp as the Sigma 18-35mm Art, it\u2019s a worthy investment that will likely outlast the camera body you&#8217;re currently using. The knurling on the ring is also perfectly textured for easy adjustment even with gloves on.<\/p>\n  <p class=\"purchase-links\"><span class=\"amazon-region-btn\">Check Price on <a href=\"https:\/\/www.amazon.com\/s?k=B+W+72mm+Master+CPL+MRC+Nano&#038;tag=e6890-20&#038;linkCode=osi\" target=\"_blank\">Amazon US<\/a>, <a href=\"https:\/\/www.amazon.co.uk\/s?k=B+W+72mm+Master+CPL+MRC+Nano&#038;tag=pctest07-21&#038;linkCode=osi\" target=\"_blank\">UK<\/a>, <a href=\"https:\/\/www.amazon.ca\/s?k=B+W+72mm+Master+CPL+MRC+Nano&#038;tag=pctestt-20&#038;linkCode=osi\" target=\"_blank\">CA<\/a>, <a href=\"https:\/\/www.amazon.de\/s?k=B+W+72mm+Master+CPL+MRC+Nano&#038;tag=67990-21&#038;linkCode=osi\" target=\"_blank\">DE<\/a> \u2192<\/span> <a href=\"https:\/\/www.bhphotovideo.com\/c\/search?Ntt=B+W+72mm+Master+CPL+MRC+Nano&#038;BI=8941&#038;KBID=10361&#038;SID=12345&#038;DFF=d50\" target=\"_blank\" class=\"purchase-link-bh\">Check Price on B&#038;H<\/a><\/p>\n  <p class=\"secure-payment\">\u2713 Free Shipping \u00b7 \u2713 Easy Returns \u00b7 \u2713 Secure Checkout<\/p>\n<\/div>\n\n<div class=\"top-recommendation\" data-badge=\"also-great\">\n  <div class=\"top-badge badge-also-great\">\ud83d\udc4d Also Great<\/div>\n  <h3>Breakthrough Photography X4 CPL <a href=\"https:\/\/www.amazon.com\/s?k=Breakthrough+Photography+X4+CPL+72mm&#038;tag=e6890-20&#038;linkCode=osi\" target=\"_blank\" class=\"title-amazon-btn\">View on Amazon<\/a> <a href=\"https:\/\/www.bhphotovideo.com\/c\/search?Ntt=Breakthrough+Photography+X4+CPL+72mm&#038;BI=8941&#038;KBID=10361&#038;SID=12345&#038;DFF=d50\" target=\"_blank\" class=\"title-bh-btn\">View on B&#038;H<\/a><\/h3>\n  <div class=\"product-highlights\">\n    <div class=\"highlight-item\"><span class=\"highlight-label\">Best For:<\/span> Color-Critical Landscape<\/div>\n    <div class=\"highlight-item\"><span class=\"highlight-label\">Key Feature:<\/span> SCHOTT B270 Glass<\/div>\n    <div class=\"highlight-item\"><span class=\"highlight-label\">Rating:<\/span> <span class=\"star-rating\">\u2605\u2605\u2605\u2605\u2606<\/span><\/div>\n  <\/div>\n  <p>The Breakthrough Photography X4 is widely considered the most color-neutral CPL on the market. If you\u2019ve ever been frustrated by the &#8220;warm&#8221; or &#8220;cool&#8221; cast that polarizers often introduce, the X4 is your solution. It uses SCHOTT B270 glass and features a unique &#8220;traction&#8221; frame\u2014deep ridges that make it incredibly easy to screw on and off, even if your hands are sweaty or cold. On the Sigma 18-35mm, it performs beautifully, delivering punchy contrast in skies and deep greens in foliage without messing with your white balance. One minor drawback is the price\u2014it&#8217;s right up there with the B+W\u2014and availability can sometimes be spotty compared to Hoya. However, for the photographer who prioritizes post-processing ease and physical grip, the X4 is an &#8220;also great&#8221; that might actually be your first choice.<\/p>\n  <p class=\"purchase-links\"><span class=\"amazon-region-btn\">Check Price on <a href=\"https:\/\/www.amazon.com\/s?k=Breakthrough+Photography+X4+CPL+72mm&#038;tag=e6890-20&#038;linkCode=osi\" target=\"_blank\">Amazon US<\/a>, <a href=\"https:\/\/www.amazon.co.uk\/s?k=Breakthrough+Photography+X4+CPL+72mm&#038;tag=pctest07-21&#038;linkCode=osi\" target=\"_blank\">UK<\/a>, <a href=\"https:\/\/www.amazon.ca\/s?k=Breakthrough+Photography+X4+CPL+72mm&#038;tag=pctestt-20&#038;linkCode=osi\" target=\"_blank\">CA<\/a>, <a href=\"https:\/\/www.amazon.de\/s?k=Breakthrough+Photography+X4+CPL+72mm&#038;tag=67990-21&#038;linkCode=osi\" target=\"_blank\">DE<\/a> \u2192<\/span> <a href=\"https:\/\/www.bhphotovideo.com\/c\/search?Ntt=Breakthrough+Photography+X4+CPL+72mm&#038;BI=8941&#038;KBID=10361&#038;SID=12345&#038;DFF=d50\" target=\"_blank\" class=\"purchase-link-bh\">Check Price on B&#038;H<\/a><\/p>\n  <p class=\"secure-payment\">\u2713 Free Shipping \u00b7 \u2713 Easy Returns \u00b7 \u2713 Secure Checkout<\/p>\n<\/div>\n\n<h2>Buying Guide: How to Choose a Polarizer for Sigma 18-35mm<\/h2>\n<div class=\"info-module buying-guide\">\n  <p>The Sigma 18-35mm f\/1.8 is a unique beast\u2014it&#8217;s the fastest zoom lens for APS-C sensors and delivers prime-like sharpness. When choosing a polarizer, your primary goal is to avoid &#8220;choking&#8221; that performance. You want a 72mm filter that offers high light transmission; since you likely bought this lens for its low-light f\/1.8 capability, losing 2 full stops to a cheap filter is counterproductive. Look for &#8220;High Transmission&#8221; or &#8220;HTC&#8221; labels. Furthermore, because 18mm is quite wide on crop sensors, a slim-profile frame is essential to prevent dark corners (vignetting). Expect to spend between $50 and $130; anything cheaper often introduces a color cast that will make your post-processing a nightmare. Prioritize glass quality and coating durability over brand name alone.<\/p>\n  <h3>Key Factors<\/h3>\n  <ul>\n    <li><strong>Filter Thread Size:<\/strong> You must buy exactly 72mm for the Sigma 18-35mm Art.<\/li>\n    <li><strong>Light Transmission:<\/strong> Higher transmission (like Hoya HD3 or B+W Master) lets you shoot faster in lower light.<\/li>\n    <li><strong>Frame Thickness:<\/strong> A slim mount is vital at 18mm to avoid blocking the corners of your frame.<\/li>\n    <li><strong>Coating Quality:<\/strong> Nano coatings make cleaning oils and water much easier in the field.<\/li>\n  <\/ul>\n<\/div>\n\n<h2>Comparison Table<\/h2>\n<div class=\"comparison-module\">\n  <table class=\"comparison-table\">\n    <thead><tr><th>Product<\/th><th>Best For<\/th><th>Rating<\/th><th>Price<\/th><\/tr><\/thead>\n    <tbody>\n      <tr class=\"highlight-row\"><td><strong>Hoya HD3<\/strong><\/td><td>Durability &#038; Light<\/td><td>\u2605\u2605\u2605\u2605\u2605<\/td><td><a href=\"https:\/\/www.amazon.com\/s?k=Hoya+HD3+CPL+72mm&#038;tag=e6890-20&#038;linkCode=osi\" target=\"_blank\" class=\"table-price-btn\">Check<\/a><\/td><\/tr>\n      <tr><td><strong>Marumi Super DHG<\/strong><\/td><td>Value for Money<\/td><td>\u2605\u2605\u2605\u2605\u2606<\/td><td><a href=\"https:\/\/www.amazon.com\/s?k=Marumi+Super+DHG+72mm&#038;tag=e6890-20&#038;linkCode=osi\" target=\"_blank\" class=\"table-price-btn\">Check<\/a><\/td><\/tr>\n      <tr><td><strong>Tiffen 72mm CPL<\/strong><\/td><td>Budget Shooters<\/td><td>\u2605\u2605\u2605\u2605\u2606<\/td><td><a href=\"https:\/\/www.amazon.com\/s?k=Tiffen+72mm+CPL&#038;tag=e6890-20&#038;linkCode=osi\" target=\"_blank\" class=\"table-price-btn\">Check<\/a><\/td><\/tr>\n      <tr><td><strong>B+W Master HTC<\/strong><\/td><td>Premium Build<\/td><td>\u2605\u2605\u2605\u2605\u2605<\/td><td><a href=\"https:\/\/www.amazon.com\/s?k=B+W+Master+CPL+72mm&#038;tag=e6890-20&#038;linkCode=osi\" target=\"_blank\" class=\"table-price-btn\">Check<\/a><\/td><\/tr>\n      <tr><td><strong>Breakthrough X4<\/strong><\/td><td>Color Accuracy<\/td><td>\u2605\u2605\u2605\u2605\u2606<\/td><td><a href=\"https:\/\/www.amazon.com\/s?k=Breakthrough+X4+CPL+72mm&#038;tag=e6890-20&#038;linkCode=osi\" target=\"_blank\" class=\"table-price-btn\">Check<\/a><\/td><\/tr>\n    <\/tbody>\n  <\/table>\n<\/div>\n\n<h2>Frequently Asked Questions<\/h2>\n<div class=\"faq-module\">\n  <div class=\"faq-item\"><h3>What filter size does the Sigma 18-35mm f\/1.8 use?<\/h3><p>The Sigma 18-35mm f\/1.8 DC HSM Art lens uses a 72mm filter thread.

All the recommendations on this list, especially the Hoya HD3 and B+W Master, are designed with thin rings specifically to prevent dark corners at the wider end of your focal range.<\/p><\/div>\n  <div class=\"faq-item\"><h3>Does a polarizer affect the f\/1.8 aperture?<\/h3><p>A polarizer doesn&#8217;t change the physical aperture, but it does reduce the amount of light reaching the sensor, typically by 1 to 2 stops. If you&#8217;re shooting at f\/1.8 in low light, adding a CPL might force your camera to raise the ISO or slow the shutter speed. This is why &#8220;High Transmission&#8221; polarizers are so valuable\u2014they minimize this light loss while still providing the glare-cutting benefits.<\/p><\/div>\n  <div class=\"faq-item\"><h3>Can I leave the polarizer on all the time?<\/h3><p>While you can, it\u2019s not recommended. Polarizers are specific tools for cutting glare and enhancing sky contrast. Leaving it on in low light or at night will unnecessarily reduce your light intake and could introduce lens flare from streetlights. I suggest using a dedicated UV or Protector filter for everyday lens protection and only swapping to the CPL when the lighting conditions actually call for polarization.<\/p><\/div>\n  <div class=\"faq-item\"><h3>How do I clean a nano-coated filter?<\/h3><p>Nano-coated filters like the Hoya HD3 or B+W Master are actually easier to clean because they repel oil. Use a blower first to remove loose grit (to avoid scratching), then use a clean microfiber cloth. If there\u2019s a stubborn smudge, a single drop of specialized lens cleaning fluid or a LensPen will usually do the trick. Avoid using t-shirts or paper towels, as these can damage the delicate coatings over time.<\/p><\/div>\n<\/div>\n\n<h2>Final Verdict<\/h2>\n<div class=\"conclusion-module verdict-box\">\n  <div class=\"verdict-picks\">\n    <div class=\"verdict-item\">\n      <span class=\"verdict-label\">\ud83c\udfc6 Best Overall:<\/span>\n      <div class=\"verdict-product\">\n        <strong>Hoya HD3 Circular Polarizer<\/strong>\n        <span class=\"verdict-reason\">\u2013 Unbeatable light transmission and toughness.<\/span>\n      <\/div>\n      <a href=\"https:\/\/www.amazon.com\/s?k=Hoya+HD3+CPL+72mm&#038;tag=e6890-20&#038;linkCode=osi\" target=\"_blank\" class=\"verdict-btn\">Buy Now<\/a>\n    <\/div>\n    <div class=\"verdict-item\">\n      <span class=\"verdict-label\">\ud83d\udc8e Best Value:<\/span>\n      <div class=\"verdict-product\">\n        <strong>Marumi Super DHG CPL<\/strong>\n        <span class=\"verdict-reason\">\u2013 Pro-level glass at a mid-range price.<\/span>\n      <\/div>\n      <a href=\"https:\/\/www.amazon.com\/s?k=Marumi+Super+DHG+72mm&#038;tag=e6890-20&#038;linkCode=osi\" target=\"_blank\" class=\"verdict-btn\">Buy Now<\/a>\n    <\/div>\n    <div class=\"verdict-item\">\n      <span class=\"verdict-label\">\ud83d\udcb0 Budget Pick:<\/span>\n      <div class=\"verdict-product\">\n        <strong>Tiffen 72mm CPL<\/strong>\n        <span class=\"verdict-reason\">\u2013 Affordable and effective for beginners.<\/span>\n      <\/div>\n      <a href=\"https:\/\/www.amazon.com\/s?k=Tiffen+72mm+CPL&#038;tag=e6890-20&#038;linkCode=osi\" target=\"_blank\" class=\"verdict-btn\">Buy Now<\/a>\n    <\/div>\n  <\/div>\n  <p class=\"verdict-summary\">For most Sigma 18-35mm owners, the Hoya HD3 is the smartest investment\u2014it preserves the lens&#8217;s low-light strengths better than almost anything else. If you&#8217;re on a tighter budget but still want that Japanese optical quality, the Marumi Super DHG is a fantastic alternative. Professionals who demand the most rugged brass construction should look no further than the B+W Master.
