The Canon PowerShot G7 X Mark III is a compact point-and-shoot camera suitable for vlogging. It can capture good quality shots that remain mostly free of noticeable visual noise, so your images shouldn't appear very grainy, and you can also use this camera to live stream directly to YouTube, though we don't currently test this. It has a touch-sensitive screen that can get bright enough that you can still see it under direct sunlight. You can also use it to navigate its menu or flip it upwards to face you when the camera is pointed at you.

Unfortunately, its battery performance is poor and can frequently interrupt your shooting sessions by overheating the camera and shutting it down. Its autofocus is also middling in photography and struggles to track faces and moving objects.

Our Verdict

7.1 Travel Photography

The Canon PowerShot G7 X Mark III is decent for travel photography. It has good image quality, so your photos remain free of noticeable visual noise at moderate ISO levels. This means your images shouldn't appear very grainy. However, they don't stay as sharp as you bump up the ISO, and it has a disappointing autofocus performance as it struggles to track faces and moving objects. That said, it's incredibly portable and has a textured handgrip, which makes it easier to hold in comparison to other compact cameras we've tested.

Pros
  • Good image quality.
  • Outstanding portability.
Cons
  • Sub-par autofocus performance.
  • Frequently shuts down due to major overheating issues.
7.2 Landscape Photography

The Canon PowerShot G7 X Mark III is good for landscape photography. Its image quality is good, ensuring most images remain sharp and free of visual noise. It's decently well-built and is comfortable to use and hold. Its screen can also get outstandingly bright, which is great for shooting outdoors and if you need to see it under direct sunlight. Also, its lens is alright overall, though it exhibits significant light falloff, which can cause your shots to look darker around the edges in comparison to their center.

Pros
  • Good image quality.
  • Outstanding portability.
Cons
  • Frequently shuts down due to major overheating issues.
7.2 Sport & Wildlife Photography

The Canon PowerShot G7 X Mark III is satisfactory for sport and wildlife photography. It has an outstandingly high continuous shooting speed, which is good if you're snapping shots of fast-moving subjects, and also has a handy silent shooting mode that can be helpful when snapping shots of easily spooked wildlife. That said, it takes a while to clear its buffer, which doesn't make it suitable for taking long bursts back-to-back. It may also struggle to keep moving subjects in focus, which can be disappointing.

Pros
  • Silent shooting mode.
  • High continuous shutter speed.
Cons
  • Sub-par autofocus performance.
  • Takes some time to clear its buffer.
6.9 Vlogging

The Canon PowerShot G7 X Mark III is good for vlogging. It has a great screen that you can flip up to face you when the camera is pointed at you. It's also exceptionally portable, and footage taken while walking should remain smooth and stable. It can shoot in 4k and FHD without a crop; however, it does incur a reduction in your field of view when its stabilization feature is set to High. It's also okay at tracking faces, though it struggles to capture clear and sharp footage free of noticeable visual noise while shooting in 4k and FHD. Unfortunately, its battery performance is poor and frequently causes the camera to shut down from overheating, especially when shooting in 4k. This can make it hard to record long videos in 4k, so it may be best to stick to recording in FHD.

Pros
  • Outstanding portability.
  • Great video stabilization performance.
  • Screen can flip to face you.
Cons
  • Frequently shuts down due to major overheating issues.
5.6 Studio Video

The Canon PowerShot G7 X Mark III is passable for studio video. It has poor video quality when recording footage in FHD, and its video quality when recording in 4k isn't much better. It also lacks a headphone or microphone jack. That said, its internal recording capacity in FHD is good, with a bit rate range that should generate both high-quality or lightweight video files, which is useful for editing or exporting to social media.

Pros
  • Screen can flip to face you.
  • Easy-to-use menu system.
Cons
  • Poor video quality in FHD.
  • Disappointing 4k video quality.
  • Frequently shuts down due to major overheating issues.
  • Limited selection of inputs and outputs.
5.0 Action Video

The Canon PowerShot G7 X Mark III isn't designed for action video. Though it's outstandingly portable and is great at keeping videos stable, it has poor FHD video quality, and footage quality in 4k is middling. It also doesn't have an advertised rating for water resistance and can't shoot high-quality slow-motion videos in FHD or 4k.

Pros
  • Great video stabilization performance.
Cons
  • Poor video quality in FHD.
  • Disappointing 4k video quality.

Differences Between Sizes And Variants

The Canon PowerShot G7 X Mark III comes in two different color variants: Black and Silver. We tested the Black variant, and you can see the label for the model we tested here. We expect both variants to perform similarly.

Compared To Other Cameras

Sony ZV-1

The Sony ZV-1 and the Canon PowerShot G7 X Mark III perform similarly. They're both compact cameras with 1-inch sensors that are similar in size and build quality. Though the Canon doesn't have a fully articulated screen like the Sony, you can still flip its screen up to face you for vlogs, and it has a more intuitive menu system with touch navigation. The Canon's built-in lens also has a slightly longer max focal length, giving you a bit more reach. That said, while the Canon can shoot uncropped 4k video, the Sony offers more frame rate options in 1080p and has a more effective autofocus system.
