Canon PowerShot G7 X Mark III — What’s Changed
July 8, 2019
Canon’s consummate, compact video powerhouse is now in its third version. Without losing any of its appeal as a terrific stills plus video/vlogging camera, the PowerShot G7 X Mark III has gained some capabilities over and above its well-regarded, version II predecessor. We’ll look at the new features in this article.
- New 20.1 million pixel, 1-inch size stacked CMOS sensor
Outstanding increases in sensor read-out speed, as well as improved high ISO performance, are direct benefits of the “stacked” design of this camera’s 1-inch CMOS sensor. RAW Burst shooting up to 30 fps, and continuous shooting with Servo AF at up to 8.3 fps, are direct benefits.
The previous PowerShot G7 X Mark II used conventional sensor design, and performance was limited to an absolute maximum speed of 8.0 fps, with focus locked after the first shot.
- DIGIC 8 processor
A faster central processing unit, able to perform more noise-reduction steps for each image, and allow outstanding still-image shooting speed — as well as 4K video, from the full width of the G7 X Mark III’s image sensor.
G7 X Mark II — DIGIC 7 processor, which limited processing speed, shooting speed, and video was limited to Full HD resolution.
- Latest Canon .CR3 RAW file type
RAW images now conform to the same .CR3 file type used in latest Canon EOS DSLRs and EOS R-series mirrorless cameras.
G7 X Mark II — previous .CR2 RAW file type, not compatible with mobile RAW processing, using Canon DPP Express software for iOS tablets
- 8.3 fps continuous shooting, with full Servo AF for focus upon moving subjects
- 20 fps, with AF locked on a stationary subject, using the mechanical shutter option (which can sometimes provide better image quality, with less potential for distortion)
- 30 fps RAW Burst mode, with AF locked and electronic shutter. Up to 70 consecutive full-res, RAW images, at 30 fps shooting rate. Twenty million pixel RAW images, at drive speeds equivalent to movie shooting.
Previous G7 X Mark II: maximum speed with Servo AF was 5.4 fps; with AF locked, approx. 8.0 fps. No faster still-image shooting options.
- High-speed electronic shutter
The stacked CMOS image sensor in the PowerShot G7 X Mark III can act as its own shutter, in effect turning light-gathering for still images on and off. And, it can provide shutter speeds to an incredible 1/25,600th of a second!
G7 X Mark II: no exclusive electronic shutter option; still image shutter fastest speed was 1/2000th second.
- 4K recording, at 30 fps
High-resolution 4K recording is now possible in the PowerShot G7 series, and it’s from the full width of the image sensor (no “cropping”). This is 4x the pixel resolution of 1080p “Full HD” video, and offers great quality potential to vloggers and other video users.
Previous G7 X Mark II: Limited to 1080p resolution, at 60 fps maximum.
- Live Streaming to YouTube®
No smartphone or computer needed — engage Live Streaming on the G7 X Mark III’s menu, connect to compatible Wi-Fi, and you can Live Stream video to YouTube. G7 X Mark III is the industry’s first camera to have self-contained Live Streaming capability.
G7 X Mark II: Third-party accessories and software needed to perform Live Streaming
- 120 fps, high-speed Full HD video
Super-smooth rendering of movement, at 120 fps frame rate. Again, this uses the full width of the G7 X Mark III’s image sensor, at Full HD (1080p) video resolution.
G7 X Mark II: No slow-motion option
- Vertical movie playback
Popular in video recorded with today’s smartphones, PowerShot G7 X Mark III has an option to record vertical video, to match this popular “look” — and to play vertical videos back, properly oriented, even if they’re sent to a mobile device
G7 X Mark II: much smaller, horizontal video displayed if played back on mobile device
- 4K video Star Mode
Enhancement of the G7 series’ ability to record stars in the night sky — now possible to record video, at 4K video resolution
G7 X Mark II: Star Mode shooting limited to still-images only
- 4K Frame Grab — 8.3 million pixel still image files, from 30 fps video clips
Record 4K video, with continuous autofocus and up to 10 minutes of uninterrupted shooting. Review on the G7 X Mark III’s LCD monitor, select your choice of still frame(s) from the video, and save them as independent, still image files, on the camera’s memory card.
Previous G7 X Mark II: no 4K at all; no still-image Frame Grab in-camera from video
- Picture Style — same as EOS DSLRs and mirrorless
Canon’s Picture Style is now in the G7 X Mark III, and the same image fine-tuning is possible for JPEG images (in-camera), or for RAW images (in-camera, and when processed in Canon’s DPP software). Especially important for current Canon EOS users, adding G7 X Mark III as a compact alternative to interchangeable lens cameras.
Previous G7x version: Different in-camera image adjustments, with limited RAW image control in-camera. Unrelated to EOS-standard Picture Style adjustments.
- Focus Bracketing
Take many images with fine, user-set shifts in the plane of focus — then have them gathered and processed in compatible versions of Canon’s DPP software, into one finished image with extensive front-to-back sharpness.
G7 X Mark II: Far more limited Focus Bracketing, capable of only 3 shots, with no in-camera processing into one finished image.
- Now with Bluetooth, in addition to Wi-Fi
G7 X Mark III adds Bluetooth connectivity for a low-power means of retaining steady connection to mobile devices, with ability to immediately switch to more powerful Wi-Fi method when it’s time to display or send images/video files between the camera and compatible mobile devices
G7 X Mark II: With no Bluetooth, Wi-Fi connections are harder, and often must be re-connected after a session is concluded.
