The Campark X40 is an incredibly portable action camera with a wide array of accessories in the box. It has a great video stabilization feature that does an especially good job of reducing camera shake in FHD. However, its video quality is poor in both 4k and FHD, especially in low light. On the upside, it's advertised to be waterproof up to 40m, but only when using the included case, which adds some bulk. Note also that we don't currently test water resistance. It records video at up to 120 fps in FHD, which is good for generating slow-motion video, but it isn't capable of recording at 240 fps in FHD and is limited to 30 fps in 4k.

Our Verdict

3.6 Travel Photography

The Campark X40 is a poor choice for travel photography. While it's very small and portable, making it easy to travel with, it isn't meant for still photography, so it has a fixed fisheye lens that distorts the image. It doesn't have an autofocus system either, and its fixed aperture and limited shutter speed range leave little flexibility for taking photos.

Pros
  • Highly portable.
  • Waterproof with included case.
Cons
  • Fixed focal length and aperture.
  • Limited shutter speed.
  • No autofocus.
4.5 Landscape Photography

The Campark X40 isn't meant for landscape photography. While it takes relatively sharp photos, its fixed lens limits what you can do with it and has an ultra-wide focal length that creates a fisheye effect and distorts the image. Its dynamic range is also inadequate for landscape photos. On the upside, it's incredibly portable, so you can easily take it to remote shooting locations.

Pros
  • Highly portable.
  • Waterproof with included case.
  • Photos look relatively sharp.
Cons
  • Fixed focal length and aperture.
  • Limited shutter speed.
  • No autofocus.
2.3 Sport & Wildlife Photography

The Campark X40 is bad for taking photos of sports and wildlife. Its continuous shooting mode is very limited, as it can only take three-shot bursts at a speed of 3 fps. It also has a fixed lens with a focal length that you can't adjust, so you can't zoom in on far-away subjects. The lens is also fixed to a wide-angle field of view, creating a fisheye effect that distorts the image.

Pros
  • Highly portable.
  • Waterproof with included case.
Cons
  • Fixed focal length and aperture.
  • Limited shutter speed.
  • No autofocus.
7.0 Vlogging

The Campark X40 is okay for vlogging. It's incredibly portable, making it easy to vlog on the go. It also has a front-facing screen so you can monitor the live view while you're recording and ensure you're always in frame. It does an excellent job of smoothing out camera shake in FHD and 4k when walking at a moderate pace. That said, the lack of any handgrip means you likely need to buy a handle or other accessories to vlog comfortably.

Pros
  • Very good video stabilization.
  • Highly portable.
  • Waterproof with included case.
Cons
  • Fixed focal length and aperture.
  • Limited shutter speed.
  • Poor overall video quality.
4.9 Studio Video

The Campark X40 is a poor choice for studio video as it isn't for this use. Its overall video quality is bad, and the fixed lens has a fisheye effect that distorts the image. It also lacks microphone and headphone jacks. While it does have a micro HDMI port, you can only use it for playback on an external monitor. It also lacks an autofocus system.

Pros
  • Highly portable.
  • Waterproof with included case.
Cons
  • Fixed focal length and aperture.
  • Limited shutter speed.
  • Poor overall video quality.
6.6 Action Video

The Campark X40 is mediocre for action video. It's incredibly portable, and you can easily mount it on a helmet or chest rig for first-person action video. Unfortunately, it's only waterproof with the included case, which adds quite a bit of bulk. It has good video stabilization in 4k, and it does an even better job smoothing out camera shake in FHD. That said, its video quality is bad, with a lot of banding and color shifting in low light. It also only shoots video up to 120 fps.

Pros
  • Very good video stabilization.
  • Highly portable.
  • Waterproof with included case.
Cons
  • Fixed focal length and aperture.
  • Limited shutter speed.
  • Poor overall video quality.
  • 3.6 Travel Photography
  • 4.5 Landscape Photography
  • 2.3 Sport & Wildlife Photography
  • 7.0 Vlogging
  • 4.9 Studio Video
  • 6.6 Action Video

  • Menu is simple and very easy to navigate with the touchscreen but more tedious when using the buttons
  • By default, camera locks the screen after 30 seconds, which helps mitigate accidental touches
  • Included 'Bracelet Remote' lets you take photos and record remotely
  • When connected to the 'DV King 4k' companion app, you lose access to camera functions on the camera itself and can only operate it using the app; the camera simply shows basic information while connected to the app, as seen here
