Underwater photography is a challenging field. Performance is key and you need a camera you can trust. Being able to handle fast-moving subjects, low light conditions, and having a great range of lenses available to you is paramount. 

DSLRs have always been the most popular choice in the underwater photography community. But now mirrorless cameras are on the rise, with many of the industry’s biggest players focusing on their mirrorless camera lines.

Many professional photographers have been making the switch to mirrorless in recent years.

However, it isn’t all about DSLR or mirrorless; compacts and waterproof action cameras are also great choices, especially for those just getting started in this awesome industry, or for those on a tighter budget.

Yet, in the realm of underwater photography, it’s not solely about the camera. External factors like a waterproof housing options, image stabilization, and even battery life play a pivotal role in the final quality of your images.

In essence, the best camera for underwater photography is one that suits your needs, withstands the challenges of the deep, and ultimately captures breathtaking images that bring the underwater world to life on the surface.

Features of the best cameras for underwater photography

Here are some of the key features you should consider when deciding on a camera for underwater photography.

1. Full Frame, crop or Micro Four Thirds

Full frame cameras offer advantages such as higher image quality and ISO capabilities, full frame cameras are typically more expensive, and both DSLR and mirrorless cameras are available as full frame.

Traditionally, a crop sensor camera is cheaper and slightly smaller. Due to the sensor, the lenses are slightly more zoomed in when compared to the full frame.

This can be helpful for close-up portraits of fish or macro photography, as you can keep a greater distance between you and the subject.

Micro Four Thirds (or M43) is cheaper again, and these cameras are far more lightweight and compact. They do however offer fewer megapixels, averaging around 20mp.

M43 is more zoomed in than a crop sensor, it would be 2x as magnified when compared to a full frame.

2. Autofocus

Many newer cameras offer autofocus and focus tracking, and systems such as AI autofocus are capable of learning from your shooting and movement, helping to keep those fast-moving subjects in focus.

Many systems perform well tracking animals and eyes on the surface, but haven’t been thoroughly tested on underwater subjects. Remember that a higher number of autofocus points will make it easier to track and maintain focus on your subject.

3. Low light capabilities

The conditions underwater are typically darker than on land. We begin to lose light and colour as soon as we drop below the surface.

You don’t want to be limited by poor performance in low light conditions, and in darker environments, you will need to be prepared to raise your ISO.

Of course, with higher ISO comes digital noise in your images, and dramatic noise at high ISO will ruin images. So, full-frame cameras with larger sensors are traditionally the best in low light.

But look out for other features like stabilization at lower shutter speeds as this can help allow you to keep your ISO lower and avoid noise.

4. Shutter speed

Shutter speed is less relevant in underwater photography than in wildlife photography on the surface, as you are using strobes.

Most strobes can only sync to 1/250 of a second unless you plan to enter high-speed sync realms. Fast shutter speed is great but of little use if your strobes can’t sync with your shutter.

The system has AI-based subject recognition to detect and track moving subjects, capable of tracking animals, eyes, and faces, plus Autofocus capabilities down to -8.5EV. 

Video specs on this system are also impressive: the Z9 can record 8K resolution at 30fps and 4K at 120fps.

The price of over £5,000 will take this above the budget of many underwater photographers, but it does have some serious quality to be considered.

Another new feature for this Sony is in-body stabilization with 8 stops of image correction. This camera is more suited to photographers than videographers.

Despite being able to capture 8K video at 24fps and 4K at 60fps, the high resolution may lead to noise at higher ISO. 

Guide price: £3,599

The compact features a 25-100mm equivalent lens and offers both a microscope mode and underwater shooting mode. 

With a 100-12,800 ISO range this camera can deliver good images in low light, but noise may be a factor with a sensor this small. In addition, this system can shoot 4K video at 30fps and 1080p up to 120fps.

Guide price: £399

In conclusion

Focus tracking has traditionally been hit-and-miss with underwater subjects, but many of the newer AF systems can handle underwater subjects well. Video capabilities are often an important factor of an underwater camera, even if it will primarily be used for photography.

I would also advise buying the best sensor your budget will allow, being able to get great quality images in low light conditions is a huge advantage.

It is very frustrating when your camera lacks quality in dark underwater environments. There certainly is a lot to think about when purchasing an underwater camera, but there are many options for a variety of budgets, so do your research before buying.

Happy shooting!
