What Filters Should I Buy for Beach Photography
My first filter purchase for beach photography would be a good circular polarizer. My second would depend on the photographs: a six-stop neutral density filter for moving water, or a clear protector if the real problem is windblown sand and salt spray. I would buy a ten-stop ND only when long exposures become something I actually want to make. That is a smaller shopping basket than the usual beach photography kit, and a more useful one. Bright sunshine alone does not mean you need a filter; a fast shutter speed is often exactly what a beach photograph needs.
The photograph here explains the distinction rather nicely. On the right, a woman with curly auburn hair wears dark sunglasses with thick black arms, her face turned toward the camera she holds in front of her. Her bare forearms make a diagonal across the frame, and turquoise nail polish supplies a small, unexpectedly bright accent against the black camera and deeply ribbed lens barrel. A petal-shaped hood projects from the lens, while the loose camera strap hangs beneath her hands. Along the lower right edge, a patterned shoulder strap and a sliver of dark clothing add texture. Behind her, the beach dissolves into broad patches of pale sand, dark parasol roofs, white upright structures, indistinct visitors and washed blue sky. It feels hot, busy and very bright. The soft background keeps the attention on her face, hands and equipment, rather than turning every beachgoer into a competing subject. We cannot establish the exact camera, lens, exposure or presence of a filter from this view, but we can see why a hood and sensible handling matter.

For a concrete starting purchase, I would choose the Hoya HD nano Mk II CIR-PL in 67mm if my main beach lens took a 67mm filter. Its appeal for this job is practical: a slim rotating mount and water- and oil-repellent coatings, rather than the promise of instant postcard colors. This is a buying recommendation based on its specification and intended use, not a claim that I have personally tested this particular filter on the beach. The links in this article open product searches, so check the exact model, diameter, seller and delivery terms before ordering. Different Hoya generations have very similar names.
A circular polarizer earns its place when glare is hiding something you want to photograph. Rotate it while watching the water or a wet rock, rather than simply turning until the sky looks darkest. At a suitable viewing angle, it can reduce reflections from the water enough to reveal submerged stones or a more distinct color beneath the surface. It can also bring out texture in wet surfaces. The effect depends on the light and your position; it will not make every stretch of sea transparent, and it cannot remove every bright reflection. Sometimes the sparkle is the photograph. I would take a frame with the effect reduced as well as one with stronger polarization, because removing all the life from the water is surprisingly easy.
The polarizer is less automatic for people. For a candid scene like this one, I would first make sure the shutter speed was fast enough for hands, hair and small movements. A polarizer costs light, and leaving it fitted as you walk into shade can push the camera toward a slower shutter or higher ISO. Sunglasses and other reflective objects can also change appearance as you rotate it. Use the filter to solve a visible problem. If the portrait already works, the fact that you brought a polarizer is not an obligation to use it.
Very wide lenses need particular restraint. Across the broad sky covered by a Canon RF 16mm on full frame, or the wide end of an RF-S 10-18mm on APS-C, polarization can produce an uneven dark patch because the effect varies with angle to the sun. That is an optical effect, not necessarily a faulty filter. I would use weaker polarization, change direction, exclude some sky or take the filter off. Panoramas are another occasion to be cautious, since the sky can change markedly across the sequence. A slim mount helps with mechanical corner shading; it does not fix uneven polarization.
Buy the diameter for the lens, not for the camera body. The Canon RF 24-105mm F4-7.1 IS STM and RF 100-400mm F5.6-8 IS USM both take 67mm filters. The RF-S 10-18mm F4.5-6.3 IS STM takes 49mm, while the RF 16mm F2.8 STM takes 43mm. These are specific lens models: the RF 24-105mm F4 L, for example, has a different filter size. Look for the diameter symbol on the lens or check its manual before buying. An EOS R8 or R100 does not have a universal filter size, however convenient that would be.
For a kit built around those four lenses, one 67mm polarizer is a sensible economical starting point. It fits the two larger lenses directly, and a 49mm-to-67mm step-up ring or 43mm-to-67mm step-up ring can adapt the smaller ones. The smaller number is the lens thread; the larger number is the filter thread. Use a single direct adapter where possible, and check corner shading at the widest setting. The enlarged filter can interfere with a hood or the original cap, so buy a matching 67mm cap and accept that sharing has a handling cost. If the RF-S 10-18mm lives on your camera and compactness matters most, a dedicated 49mm Hoya HD nano Mk II CIR-PL is the tidier purchase. The specified Hoya range starts at 49mm, so the 43mm RF 16mm needs an adapter for this model.
For water movement, my first fixed ND choice would be the Hoya PROND EX 64 in 67mm. ND64 means six stops of light reduction, also written ND 1.8. Unlike a polarizer, its main job is simply to let you use a longer exposure or wider aperture in the available light. If the correct unfiltered exposure at your chosen aperture and ISO is 1/125 second, six stops takes it to about half a second. That is a useful starting point for drawing retreating foam into lines while keeping more wave structure than a very long exposure would retain. It will not guarantee half a second in every situation; measure the light first.
For noticeably longer exposures, choose the Hoya PROND EX 1000 in 67mm, a nominal ten-stop filter, also labeled ND 3.0. Starting from the same unfiltered 1/125 second, ten stops gives approximately eight seconds. Water becomes much smoother and people moving through the frame may blur or partly disappear. They are not guaranteed to vanish, especially if they stop. This is a tripod purchase as much as a filter purchase: keep the support secure, watch the incoming tide and do not let the feet settle during the exposure. Compose and establish focus before fitting a dark filter if the camera struggles to see through it. A timer or remote release helps avoid touching the camera as the exposure starts.
If you know that slow exposures will be a regular interest, compare the Hoya PROND EX 8, 64 and 1000 kit in 67mm against buying the six- and ten-stop filters separately. The ND8 adds three stops, useful for modest shutter reduction or keeping a wider aperture in bright light. Check the actual bundle contents and diameter; a cheaper set in the wrong size is not much of a bargain. I would choose one fixed filter first if I was still discovering whether I liked the look. Silky water is a creative option, not a compulsory improvement.
A variable ND makes more sense to me for video than as a first beach stills filter. It lets you adjust density while keeping a chosen shutter speed, which is useful as the light changes. Its complications include uneven density or a dark cross pattern at excessive settings, particularly with wide lenses, and possible color shifts. Stacking it with a separate polarizer can introduce further unpredictable effects. For stills, I prefer the simpler decision of ND64 or ND1000 and a measured exposure. For beach portraits at a very wide aperture, a lighter ND can help when the required shutter speed exceeds the camera’s available limit; with flash, the synchronization method also affects the choice. A ten-stop filter is generally far too much for an ordinary handheld portrait.
The optional protective purchase is a Hoya HD Mk II Protector in 67mm, sized to the lens that will actually face the spray. Its toughened glass and repellent coatings make it a reasonable sacrificial surface to clean. A good clear protector does not darken the water, balance a bright sky or cure haze. Nor does it seal a camera against saltwater. I would fit it when spray and grit were a realistic nuisance, then remove it if strong backlight produced additional flare. A UV filter is not a necessary extra layer for most modern digital beach photography. Avoid stacking a protector beneath every other filter, especially on an ultrawide lens.
Cleaning is where a useful filter can become an expensive scratched filter. Blow loose grains away before touching the glass, then use appropriate lens-cleaning fluid and a clean cloth or tissue for residue. Never rub sand around with a dry shirt. Keep a second clean cloth in a sealed bag, change filters out of the wind and keep the threads free of grit. Tighten them gently; salty, sandy threads do not improve with force. The petal hood in the photograph is already doing useful work by shading the lens from stray light at suitable angles and providing some separation from accidental contact. Keep using the hood whenever the filter arrangement permits.
I would leave graduated ND filters for later. They can be useful when a bright sky sits above a relatively straight sea horizon, but their fixed transition becomes awkward around people, buildings or cliffs. For a static scene, careful exposure or bracketed frames may solve the problem without another purchase. For beachgoers, breaking waves and windblown hair, timing and an appropriate shutter speed usually deserve the attention first. No filter restores highlights that have already clipped, so watch the exposure rather than assuming tinted glass will rescue everything.
My actual starting order for a 67mm Canon beach kit would be the Hoya HD nano Mk II CIR-PL, followed by the PROND EX 64 if moving-water photographs appeal. Add the PROND EX 1000 for exposures measured in seconds, and the HD Mk II Protector when salt spray justifies it. Choose adapters only for lenses you expect to use with the filters. For a casual afternoon photographing people along the promenade, I might carry just the polarizer in its case and leave the lens bare most of the time. There is plenty happening in a beach photograph before the shopping begins.
