A few years ago we had our GoPro Hero 9 Black fail completely out of the blue, not long after the one-year warranty expired. It was a frustrating experience to say the least, and was the ultimate catalyst for our switch to the DJI Osmo Action camera line. Since then, we haven't looked back.
Our Osmo Action 4 has been an absolute workhorse aboard, but as liveaboard sailors and YouTube creators, the classic rule always weighs heavily on us: "One is none, and two is one."
When you're sailing in remote parts of the world, there are no tech shops. So as we prepare to cross the Pacific, we’ve been looking for the perfect secondary action camera.
With the arrival of the new flagship DJI Osmo Action 6 and the GoPro HERO13 Black, we have two heavy hitters competing for a spot. Has GoPro done enough to win us back, or does the new DJI Action 6 hold the crown? Let's dive in and compare the features and functionality of both to find out in this Osmo versus GoPro review, and at the end I'll tell you what we chose.

Let’s start with a look at the specifications. I’ve selected features that are more relevant to people like us, who want to record their adventures in a variety of locations, including underwater and at night.

As you can see there is quite a difference in price, and interestingly I have seen the GoPro getting cheaper and cheaper, while the DJI stays consistent. This might be an indication of buyers voting with their wallets...
Looking at the waterproof depth, you can increase that for both camera's down to 60m by buying either the GoPro Protective Housing or Osmo 6 Waterproof Case.
Comparing the sensors
One of the biggest jumps for the DJI Osmo Action 6 is the transition to an innovative 1/1.1-inch square CMOS sensor.
As a content creator managing both a YouTube channel and social media pages (like Instagram and Facebook), this is a massive game-changer. Historically, if I wanted to capture a scene for a YouTube vlog (16:9 landscape) and a Reel or Short (9:16 vertical), I had to either film the same action twice or crop a wide shot so tightly in editing that it lost almost all its resolution and looked pixelated.
The square sensor on the Action 6 solves this. In the new "4K Custom" mode, the camera records the entire square sensor area. In post-production, I can export a high-definition 4K landscape clip for our main videos and a crisp 4K vertical clip for social media from the exact same video file. It's a time-saver that makes solo vlogging on a moving boat less chaotic.
GoPro's HERO13 Black retains a 1/1.9-inch sensor with an 8:7 aspect ratio. While this also allows some cropping flexibility in editing, it doesn't give you the same sensor surface area or high-resolution vertical outputs the square DJI sensor provides.
Low light & variable aperture
If you’ve ever used an action camera to film a hike under a dense jungle canopy or in the evening, you know how quickly the footage can turn grainy and unusable. Our Osmo Action 4 was a major upgrade in low light compared to our older GoPros, but we still had to be intentional with lighting when filming in low light.
The DJI Osmo Action 6 introduces a variable physical aperture of f/2.0 to f/4.0.
At f/2.0, the Action 6 lets in significantly more light than the fixed f/2.8 lens on past models and the GoPro HERO13. When we're hiking through shaded trails (like our adventures to Blue Basin in Trinidad) or capturing dinner on deck as the sun goes down, this wider aperture naturally keeps the ISO low and the footage clean. When the sun is blindingly bright on the water, the camera closes down to f/4.0 to keep the image sharp and correctly exposed.
By comparison, the GoPro HERO13 Black is stuck with a fixed f/2.8 aperture. To adapt to changing light, it relies entirely on shutter speed and ISO adjustments, which can result in more noise in low-light environments.
New lens options
The GoPro HERO13 supports their new HB-Series lenses, with Macro, Ultra Wide, and Anamorphic options. These are specialized glass lenses that the HERO13 automatically detects when you screw them on, adjusting the camera settings instantly. It’s a cool feature for creative filmmakers, but as an off-grid adventurer, I prefer to rely on a single, high-quality lens cover that can be easily replaced if scratched.
Physical Mounting: Did GoPro copy DJI?
Something I love about the DJI action cameras is the mounting system. GoPros have always used fixed folding fingers at the bottom of the camera, requiring you to manually thread and screw a long locking pin every single time you want to swap mounts.
DJI introduced a magnetic quick-release system where the entire mounting plate snaps securely onto the base of the camera with strong magnets and mechanical clips. You can swap the camera from a chest mount to a selfie stick in literally two seconds.
For the release of the HERO13 Black, GoPro has finally introduced their own magnetic latch mount. It works similarly to DJI's system, BUT, is generally sold separately - the standard GoPro still includes the built-in folding fingers and a 1/4-20 tripod thread as its standard mounting option.
Setup & app annoyances
To get both cameras up and running, you have to navigate their initial setup processes.
A persistent annoyance with DJI cameras is the requirement to use the DJI Mimo app to activate the camera. You can only bypass this prompt 5 times before the camera locks you out until activation is complete. Compounding this, the Mimo app is not available on standard mobile app stores; you have to download the APK file directly from DJI's website.
For security-conscious users, this is a pain. I originally downloaded the app on an old phone using local Wi-Fi just to complete the activation process. Fortunately, once activated, you don't need the app again unless you want to do a firmware update or use remote monitoring.
The GoPro HERO13 Black relies on the GoPro Quik app for activation and updates, which is easier to find on the App Store. Once configured, GoPro's on-camera menu system remains highly customizable.
Battery life and compatibility
Action cameras are notorious for overheating and draining batteries rapidly, especially when shooting high-resolution footage in hot tropical climates.
DJI addresses this with the new 1950mAh Extreme Battery Plus, providing up to 4 hours (240 minutes) of runtime on the Osmo Action 6. Even better, the size and shape remains the same, so if you have a stack of older 1770mAh batteries (like I do!) they are backwards compatible.
GoPro's HERO13 Black features a redesigned 1900mAh Enduro Battery that promises up to 2.5 hours of continuous recording. However, this new battery has a completely different physical footprint than previous models. Your older batteries from the GoPro HERO12, 11, or 10 will not fit in the HERO13, which is a disappointing step backward for long-term users.
Which camera wins?
Deciding between the DJI Osmo Action 6 and the GoPro HERO13 comes down to your shooting style and environment.
The GoPro HERO13 Black will likely appeal to filmmakers who want to experiment with the new HB-Series Lens Mods, prefer HyperSmooth stabilization, or require highly advanced 10-bit HLG color profiles for heavy color grading in post-production.
However, for vloggers and content creators, I think the DJI Osmo Action 6 is the clear winner. The variable aperture and massive square sensor solve two of the biggest headaches we face; capturing clean footage in low-light and cropping high-quality video for multiple social platforms at once. Add in 4-hour battery life, full backward compatibility with our existing mounts and batteries, and the waterproof rating, and you can see where this is heading...
After transiting through the Panma Canal, we purchased the DJI Osmo Action 6 as our new camera for the upcoming Pacific adventure!
