The ND Filter Most Photographers Actually Need (And Two Others Worth Knowing About)

If you've ever wanted to photograph a silky waterfall in the middle of the day, or blur ocean waves into something that looks painted, you need an ND filter. This is the one accessory that genuinely changes what's possible with your camera — and it costs a fraction of what most glass does.

The problem is the market is a mess. You've got fixed vs. variable, cheap resin vs. optical glass, and about 40 brands all claiming to be the best. Let me cut through it.

For most photographers, one variable ND and one fixed 10-stop covers almost every scenario you'll encounter. Here's how to pick them.

First: fixed or variable?

Fixed ND filters use a single piece of glass. Variable ND filters use two rotating polarizers. That construction difference matters. Fixed filters produce cleaner, more color-accurate images, especially at extreme densities. Variable filters trade some of that optical purity for convenience. You can adjust light reduction without swapping filters.

If you shoot primarily landscapes on a tripod and take your time setting up a shot, go fixed. If you shoot handheld, move fast, or do any video work, go variable. A lot of people end up with both eventually, and that's the right answer.

The budget pick: K&F Concept Variable ND2-ND400

The K&F Concept Variable ND2-ND400 holds the number-one bestseller position in camera ND filters on Amazon, with over 12,500 reviews. At around $38, it's the easiest way to find out whether ND filters fit your workflow before spending real money.

What's good

The price-to-utility ratio is hard to beat. You get a wide density range that handles most daytime shooting situations. It works. It won't embarrass you. And the sheer volume of reviews means you know what you're getting.

What's bad

Color casts. Variable NDs at this price point introduce a warm or cool shift that needs correcting in post. The coatings are functional but not exceptional, so you'll see more flare than you would with a premium filter. And like all variable NDs, push it too far toward maximum density and you'll get the dreaded X pattern across your image.

What's missing

No hard stop system to prevent the X effect. No nano-coating. And you won't get the color neutrality that matters when you're shooting landscapes and need accurate white balance straight out of camera.

Who should buy it: Someone trying ND filters for the first time, or anyone who needs a backup filter without spending $150.

The sweet spot: K&F Concept True Color VND+CPL 2-in-1

The K&F Concept True Color VND+CPL 2-in-1 comes in under $100 and solves two problems at once. It combines a variable ND with a circular polarizer into a single unit. One twist gives you both glare reduction and light reduction. For landscape and travel photographers, that's a genuinely useful combination.

What's good

The True Color coating is a real improvement over the budget model. Color shifts are much more controlled. You're also saving space in your bag by carrying one filter instead of two. For hiking and travel, that matters. (If you're already thinking about what goes in that bag, our guide to the best camera bag for hiking is worth a read.)

What's bad

Stacking two optical functions in one filter always involves some compromise. You lose a bit of contrast compared to a dedicated polarizer, and the combined unit is thicker, which can cause vignetting on ultra-wide lenses.

What's missing

Still not quite at the color neutrality level of the premium fixed options. And if you shoot video professionally, this probably isn't the filter for that work.

Who should buy it: The landscape or travel photographer who wants to simplify their kit and shoot in a wide range of conditions without swapping filters.

The upgrade: Breakthrough Photography X4 10-Stop

The Breakthrough Photography X4 10-Stop is the one you buy when you're serious about long-exposure work. It uses SCHOTT B270 glass with MRC16 multi-resistant coating. Color neutrality on this filter is about as good as it gets in a fixed ND. If you've been frustrated by the orange or blue cast in your long-exposure shots, this is usually the fix.

What's good

10 stops of light reduction opens up exposure times you can't get any other way — think 30 seconds at f/11 in full daylight. The color accuracy means you're not fighting a cast in Lightroom afterward. Build quality is excellent. This is a filter you buy once.

What's bad

It's expensive — check current pricing, but expect to pay significantly more than the variable options above. And a fixed 10-stop isn't flexible. You'll want a variable filter alongside it for situations where you need fine control.

What's missing

If you shoot video and need to swap densities quickly, the Breakthrough doesn't fit that workflow. For that use case, look at the NiSi Swift True Color ND-Vario, which is a professional-tier variable ND with genuine color accuracy across its rotation range.

Who should buy it: Anyone shooting long-exposure landscapes seriously — waterfalls, coastlines, cityscapes at dusk — and who wants the cleanest possible results without color correction headaches.

A few practical notes before you buy

Get a 77mm or 82mm filter and a set of step-up rings. That one filter will work across your entire kit. Buying a separate filter for every lens diameter gets expensive fast and defeats the point.

If you shoot video and need to swap frequently, a magnetic system is worth considering. The NiSi JetMag Pro Landscape ND Kit is a strong option here — optical quality is excellent and the twist-lock mechanism is secure enough that you won't lose a filter off the front of your lens.

Getting sharp long exposures also means dialing in your settings. If you want to nail the exposure side of things, our breakdown of the landscape photography settings that actually work covers exactly that.

Final recommendation

Start with the K&F Concept True Color VND+CPL 2-in-1. Under $100, handles most shooting situations, and the combined polarizer function makes it genuinely useful. Then add the Breakthrough Photography X4 10-Stop when you're ready to get serious about long-exposure work.

That combination covers almost everything. And it costs a fraction of what most photographers spend on gear that moves the needle far less.
