Best Underwater Housings for Mirrorless Cameras

One of the golden rules of photography is not to let your camera get wet, which is why generations of photographers have always kept their distance from the likes of waterfalls and waves, or rushed their camera into its case at the first drop of rain.

But what if you want to take pictures underwater, capturing the likes of coral reefs and aquatic environments in all of their magical glory?

In that case, you need a special underwater housing to keep your camera safe, preventing water, sand, or water pressure from damaging its delicate components.

These accessories are must-haves for the likes of marine photographers, as well as for anyone who wants to bring their camera along on their next snorkeling expedition or surfing session.

However, with so many options to choose from, you might not know where to start.

This guide is here to help. Below, I’ll share my recommendations for the best underwater housings for mirrorless cameras, including options at different price points to suit both casual and professional photographers alike.

What Is an Underwater Housing and Why Use One?

Quite simply, an underwater housing is a specialized protective case for your camera that allows you to capture images underwater without worrying about damaging your device.

These housings are made to be completely watertight, and they’re often made from strong, durable materials, like aluminum or polycarbonate. They allow you to still control your camera settings and take pictures, just like normal, while covering up all gaps and openings where water could seep in.

Underwater housings are essential items when you want to take pictures beneath the waves, but they’re not all made equal. Some have different depth ratings, for example, or various features, like lens ports for changing lenses or mounts for extra accessories, like lights and handles.

Prices can also vary quite wildly from one underwater housing to the next, with some high-end models having four-figure price tags and others being significantly cheaper.

What Are the Best Underwater Housings for Mirrorless Cameras in 2026?

Now you know what underwater housings do and the value they bring, let’s take a look at five of the best options.

1. Ikelite Deluxe 200DL Underwater Housing for Mirrorless Cameras (Best Overall)

I’ll begin with my favorite underwater housing for mirrorless cameras and what many marine photography enthusiasts agree to be one of the best models on the market today: the Ikelite Deluxe 200DL Underwater Housing.

You can find different variants of this housing to suit different brands and models of cameras, including Sony, Nikon, and others. No matter which one you choose, you’ll be getting a high-quality product with a near-flawless design.

The Ikelite 200DL has an exceptional depth rating of 200 feet, allowing you to go deep below the ocean waves to capture images while snorkeling or even scuba diving.

Its strong and sturdy frame will keep your camera safe the entire time.

But the housing isn’t just durable; it’s also very comfortable to work with, too, thanks to its built-in handles, responsive mechanical controls, and handy DL lens port system that lets you swap out lenses as and when you need to.

All purchases come with trigger extensions and spare O-rings, and the Ikelite 200DL also comes with a vacuum pump and gauge, plus a USB-C charging and data transfer bulkhead.

The only downside is its price tag: at over US$2,000, it’s one of the priciest housings you can buy.

2. AQUATECH EDGE Pro Underwater Housing (Best Design)

Next, I couldn’t compile a list like this without including the AQUATECH EDGE Pro Underwater Housing, which is compatible with a range of mirrorless cameras, including Sony’s a7R IV, a1, a7S III, and a9 II.

I’ve used this underwater housing in the past and what I love most about it is its design. Some underwater housings feel unnecessarily big and bulky, taking up too much room in my camera bag and weighing me down.

That’s not the case with this one. The AQUATECH EDGE Pro is surprisingly sleek, compact, and lightweight. It feels like a natural extension of the camera itself, rather than a cumbersome add-on, and it’s a joy to use in the likes of lakes and seas.

The tactile push-button controls and right-side palm stopper also ensure that the experience of using this housing is always a pleasant one. Meanwhile, its stainless steel and hard-anodized aluminum help it withstand even difficult environments with ease.

The big downside is depth. You can only take your camera down around 33 feet with this housing attached, which is simply nowhere near the 100 foot+ ratings provided by other models on the market.

But, if you don’t plan on going too deep, it’s an excellent buy.

3. Backscatter UH-EM10IV Underwater Octo Housing (Best Ergonomics)

The next entry on my list is the Backscatter UH-EM10IV Underwater Octo Housing, and I chose to include this for three key reasons.

Firstly, and perhaps most importantly, this case is very ergonomic and pleasant to work with. It feels strong and resilient in the hands, while providing tactile mechanical access to all of your camera’s core controls, from the shutter button to the zoom dial.

The second big advantage of the Backscatter UH-EM10IV is its surprising feature set. It comes with an RC flash trigger, for example, as well as a vacuum system. It even has a built-in alarm that detects any hint of moisture, so you can quickly take action to prevent any damage if water somehow enters the case.

Finally, while many underwater housings cost a significant amount of money, this add-on is notably cheaper than most of the others on my list. It’s not “cheap,” necessarily, but it’s a better value option for those with tighter budgets.

The only downside I can find with this model is its design. While most housings are quite simple and stark in their aesthetics, this one goes for a marine pattern theme, which may not be to everyone’s liking.

4. AOI Underwater Housing (Most Durable)

The AOI Underwater Housing is another high-quality underwater housing for mirrorless cameras, including OM SYSTEM OM-1 and OM-1 Mark II models.

This housing stands out for its durability and protection. I know from experience that it can be quite daunting to take your camera underwater for the first time, and if you want a case that will keep it completely safe, this might be the one you need.

Constructed from high-grade polycarbonate, the AOI Underwater Housing is exceptionally strong and resilient.

It can cope with saltwater and protect your camera from corrosion with ease, while its built-in vacuum and water detection system offer additional protection and peace of mind.

With a depth rating of 148 feet, you can also rely on this housing for deep water photoshoots.

The only downside is its compatibility; while other housings can work with quite a broad array of cameras, this one has a smaller selection of compatible models.

5. DiCAPac Waterproof Case for Mirrorless Camera (Best Budget Buy)

I’ll finish up my list with something a little different. This isn’t a traditional underwater housing; it’s more of a carry case, but one that was specially designed with underwater photography in mind and does offer a lot of the same features you’d expect from a full waterproof housing.

It’s constructed from a mixture of PVC, TPU, ABS, PC, and silicone, for example, which helps to keep water and sand at bay while you position your mirrorless camera beneath the surface or under the waves.

All of your camera’s controls should also remain fully operable through the case, thanks to its clever design, and it even includes a neck strap for easy carrying, plus a UV-coated lens port to prevent damage or distortion to the lens itself.

You can get all of this for a very low price when compared to the $1,000+ price tags of real underwater housings, and it’s compatible with a wide range of models, too; as long as you can fit your camera inside, you should have no trouble using the DiCAPac Waterproof Case.

With that said, there are some obvious downsides. Firstly, with a depth rating of just 16.4 feet, you cannot use this case too far below the surface. It can also be a little awkward to work with, and the design is quite basic compared to the housings mentioned above.

How to Choose the Right Underwater Housing for Mirrorless Cameras

To make sure you choose the ideal underwater housing for your mirrorless camera, keep these key factors in mind:

• Depth rating: This is arguably the most important factor to think about, because it tells you how deep below the surface you can go without risking any damage to your camera. Some housings can go several hundred feet underwater, while others are designed to stay quite close to the surface. Choose one that aligns with your photography style and intentions.
• Build quality: The whole point of an underwater housing is to keep your camera safe in one of the most dangerous environments: underwater, where sand, silt, and saltwater could seep inside and do irreparable damage. You need to make sure you choose a product that’s fit for purpose, with a strong and resilient design and protective features, like vacuums and moisture sensors.
• Compatibility: You’ll need to ensure that any underwater housing you choose is fully compatible with your make and model of camera. Many housings are available in slightly different variants to suit different cameras, but some are more restrictive. It also helps to have lens port systems so you can swap lenses accordingly.

FAQs

How deep can underwater housings go?

It depends on the housing, which is why it’s very important to check the “Depth Rating” of a housing before you buy it. Some models can reach depths of up to 200 feet below the surface, so you can comfortably dive down without having to worry about damaging your camera. Others, however, are much more restrictive and will only work at depths of a dozen feet or so.

What is the best underwater housing for mirrorless cameras?

In my opinion, the Ikelite Deluxe 200DL Underwater Housing for Mirrorless Cameras is the best option on the market right now. It stands out for its compatibility, as it works with quite a broad range of cameras, and its depth rating – it can descend to 200 feet without any problems. It’s also a strong, reliable, and long-lasting option with excellent ergonomics.

What do vacuums do in underwater camera housings?

A vacuum system in an underwater camera housing is a protective feature that essentially makes sure that the housing is completely watertight before you take it underwater. It removes air from inside the housing, creating negative pressure and sealing the camera. Many vacuum systems also come with gauges and LEDs that let you check the system is safe and sealed while in use.

You can’t risk taking your camera out into the water or even near to the water without a protective add-on to keep it safe from harm, and the best underwater housings open up a whole new world beneath the waves for you to explore and capture.
