Introduction

Ease of Use

Measuring 103.0 x 60.4 x 40.4 mm and weighing 304g including the battery and memory card, the Canon PowerShot G7 X is significantly smaller and lighter than the G1 X Mk II camera that sits above it in Canon's PowerShot range. Featuring a metal body with a solid feel and sturdy construction, the G7 X feels very well made indeed, with external controls that offer just the right amount of stiffness and resistance and are large enough to be easily and quickly accessed in the heat of the action. The Canon PowerShot G7 X will fit into a trouser or shirt pocket, but is more at home in a deep coat pocket or a small camera bag.

The Canon PowerShot G7 X features a large multi-aspect, 20.2 megapixel CMOS sensor that captures images either in the 3:2, 4:3, 16:9 or 1:1 aspect ratios whilst maintaining the same angle of view, even when shooting RAW images. The 1-inch sensor should add up to better image quality especially in low-light, greater depth-of-field, and greater dynamic range, all the things that your typical compact cameras struggles to deliver.

The G7 X has a very handy exposure compensation dial on top, a useful control that was omitted from the G1 X Mk II, although setting the ISO speed is still a rather convoluted affair. The G7 X doesn't have an optical viewfinder, and there's no way to add an electronic one either. Another grumble is that, annoyingly for such a creatively rich camera, the full user guide is still provided on CD only. In what comes across as a cursory gesture, only a very slim printed quick start guide is included in the box. Canon have also decided to only provide their software via download from their website.

Front of the Canon PowerShot G7 X

The Canon PowerShot G7 X's unassuming-looking front plate is dominated by the 4.2x zoom lens, with a bulb for the built-in self-timer/AF assist lamp flanking it on the left. Note that there's no thread included for fitting filters. The G7 X doesn't have a front control dial, as featured on EOS DSLR cameras, which makes changing the aperture and full Manual shooting mode a little more difficult.

Instead you use a combination of the lens control ring and the rear navigation wheel to change the aperture and shutter speed, each of which can be configured to suit your particular way of working. The clicking lens ring can be assigned to one of nine different settings, accessed via the Ring Function button on the rear (which itself can be customised). We found the rear navigation wheel on the rear a bit too thin to use precisely and quickly.

There's no handgrip on the Canon PowerShot G7 X, just a textured surface, which makes it more difficult easier to steady the camera, although there is a textured small pad at the back for your right thumb to rest on.

Rear of the Canon PowerShot G7 X

From left to right the G7 X's top-plate houses the folding pop-up flash, with a switch on the side for manually releasing it, a springy raised nipple-style shutter release button surrounded by a rocker switch for operating the optically stabilised 4.2x zoom (24-100mm equivalent on a 35mm camera), and behind this again the small, recessed on/off button. The fact that the lens is image stabilised, says Canon, provides a four-stop advantage when shooting handheld, while the Intelligent IS system analyses the focal length, focal distance and type of camera movement and applies the most appropriate mode from seven possible settings, and the Hybrid IS system makes shooting macros easier than before by counteracting both shift and angular movements.

The Canon PowerShot G7 X is quick to power up in a second or so, the rear LCD blinking into life with the optical zoom lens simultaneously extending from storage within the body to its maximum wide-angle setting. It starts at the equivalent of 24mm, making it very useful for those landscapes group portraits or getting the required shot in confined spaces. The G7 X's lens has bright apertures of f/1.8 at the wide-angle end of the zoom range and f/2.8 at full telephoto, plus a 9-blade aperture for better bokeh effects. As a further aid to landscape fans, a 3-stop neutral density filter option is provided among the function menu options, to be turned on or off as required, and the horizontal Electronic Level and RGB histogram can be enabled to help with composition and exposure.

Tilting LCD Screen

The G7 X has a very good continuous shooting mode, which in conjunction with Tracking AF makes it well-suited to both slow and fast moving subjects. The Canon PowerShot G7 X can capture up to 692 full-resolution JPEG shots at 6.5fps with the focus point locked at the first frame, or you can shoot continuously at 4.4fps with AF tracking.

The shooting mode dial features settings for Auto capture, Hybrid Auto, Program, Shutter Priority, Aperture Priority and Manual, along with a user customisable setting, a smattering of scene modes (8 in all), Creative Effects and Creative Shot modes, and finally a video mode. The Canon PowerShot can shoot 1080p HD video quality at 1920x1080 pixels at 60fps or 30fps, you can adjust the aperture, shutter speed and ISO, and there's manual focus peaking too. The G7 X also boasts stereo sound courtesy of tiny microphones positioned on top, and you can use the creative filters and the 5x optical zoom when filming.

The Creative Filters shooting mode contains 10 different options to help spice up your images. The High Dynamic Range mode is probably the most useful, automatically taking three exposures of the same scene at different settings, then combining them in-camera to create a single image with greater dynamic range. Note that you need to mount the G7 X on a tripod or stable surface to avoid camera-shake.

The Canon PowerShot G7 X in-hand

We appreciated the flexibility presented by the tilting LCD screen in terms of trying out unusual and formerly awkward framing. It can be tilted up through 180° for easier selfies, but it can't be tilted down. The LCD is a 3 inch monitor with 3:2 aspect ratio and a a high resolution of 1040K dots.

The Canon PowerShot G7 X has a touch focus/shoot option which is on by default. To switch it off, change the Touch Shutter option in the main menu. This then becomes a touch focus screen which will lock onto the subject wherever you touched, with a press of the Display button centering the AF point. In playback the touchscreen can be used to change the magnification of an image by spreading and pinching two fingers, and switch between images by swiping from side to side, just like on a smartphone. You can also adjust the LCD's touch sensitivity to your liking with Standard and High settings available.

On the right flank of the G7 X is a button for quickly connecting to a previously paired smartphone or tablet. The G7 X's wi-fi capabilities allow you to share images during playback via the Up button on the navigation pad. Simply enter a nickname for the camera and five more icons then appear, connecting the G7 X to another camera, a smartphone, a computer, a printer and the Internet respectively. Setup is relatively straight-forward for each scenario, although you'll need a basic understanding of the protocols involved. Note that you need to install the dedicated and free Canon CameraWindow app to connect the G7 X to an iOS or Android device.

Top of the Canon PowerShot G7 X

The G7 X's wi-fi functionality is also employed to tag your images with GPS data recorded by your smartphone ( latitude, longitude, altitude and shooting time) via the Canon CameraWindow app, which effectively replaces a more conventional built-in GPS system. We actually prefer having GPS built-in to the camera rather than having to sync it with an additional device, so in this regard the G7 X doesn't compare well with rivals that offer this feature, although it does side-step the issue of negatively affecting battery life. The G7 X also features NFC (Near Field Communication) technology (the same technology that's used for mobile payments), which allows you to connect it to a compatible Internet enabled device or another NFC-enabled camera by simply tapping them together.

Returning to the rear, alongside the Ring Function button (which also doubles up as the Delete button) is the one-touch movie record button, which as its name suggests instantly begins recording a movie at the current quality and creative settings.

Underneath this pair of controls is the four-way selection or control pad, with, at points north, east, south and west a means of selecting the burst shooting mode, choosing from the on-board flash settings, setting the Display mode, and activating manual, normal or 5cm macro focus modes. The G7 X's 31-point AF system focuses very quickly for a compact camera in either good light or bad and at both ends of the zoom range, with a slight delay of around 0.15 second.

Side of the Canon PowerShot G7 X

At its centre is the Function/Set button that is again consistent with the Canon G-series. Press this button at its centre when in any of the capture modes and an L-shaped toolbar that will be familiar to Canon users appears on the screen, offering pull out toolbars with further options from the range when you come to rest on a particular setting.

At the bottom right hand corner of the backplate are a further pairing of buttons for playing back your images and accessing the main menu. A press of the Menu button brings up a trio of folders on screen, the first the Shooting menu where the likes of the AF assist beam and blink detection modes can be turned on or off, the second the Setup menu where sound options and LCD brightness can be tweaked, and the third being a 'My Menu' option for commonly used functions.

On the right hand flank of the camera - viewed from the back - we find covered ports for HDMI out and a combined USB 2.0/AV out connection. On the bottom is a familiar metal screw thread for a tripod, and a sliding cover for the compartment that houses the lithium-ion battery needed for power and the SD, SDHC or SDXC cards needed for image storage. Battery life is not great at around 210 shots from a full charge, so you'll need to budget for at least one spare battery.

Image Quality

All of the sample images in this review were taken using the 20 megapixel SuperFine JPEG setting, which gives an average image size of around 8Mb.

The Canon PowerShot G7 X produces images of very good quality. It recorded noise-free images at ISO 125-800, with some noise at ISO 1600. ISO 3200 and 6400 show more obvious noise but still remain perfectly usable, although the fastest setting of ISO 12800 is best avoided.

The Canon PowerShot G7 X handled chromatic aberrations well, with limited purple fringing effects appearing only in high contrast situations and generally at the edges of the frame. The built-in flash worked well indoors, with no red-eye and good overall exposure, although there's noticeable vignetting at 24mm. The night photograph was excellent, with the maximum shutter speed of 30 and the Bulb mode seconds being long enough for after-dark shots.

Anti-shake works very well when hand-holding the camera in low-light conditions or when using the telephoto end of the zoom range. Macro performance is good, allowing you to focus as close as 5cm away from the subject. The images were a little soft straight out of the Canon PowerShot G7 X at the default sharpening setting and ideally require some further sharpening in an application like Adobe Photoshop, or you can change the in-camera setting.

The extensive range of My Color modes and Creative Filters make it easy to spice up your images, while the Dynamic Range and Shadow Correction modes help to etract more detail from the shadow and highlight areas.

Chromatic Aberrations

The Canon PowerShot G7 X handled chromatic aberrations well during the review, with fairly limited purple fringing present around the edges of objects in high-contrast situations, as shown in the examples below.

Chromatic Aberrations 1 (100% Crop)	Chromatic Aberrations 2 (100% Crop)

Macro

The Canon PowerShot G7 X has a good macro mode that allows you to focus on a subject that is 5cm away from the camera. The first image shows how close you can get to the subject (in this case a compact flash card). The second image is a 100% crop.

Macro	Macro (100% Crop)

Flash

The flash settings on the Canon Powershot G7 X are Auto, On, Auto Red-eye Reduction, Slow Synchro and Off. These shots of a white coloured wall were taken at a distance of 1.5m.

Flash Off - Wide Angle (24mm)	Flash On - Wide Angle (24mm)
Flash Off - Telephoto (100mm)	Flash On - Telephoto (100mm)

And here are some portrait shots. As you can see, neither the Flash On or the Red-eye-Reduction settings caused any red-eye.

Flash On	Flash On (100% Crop)
Red-eye Reduction	Red-eye Reduction (100% Crop)

Night

The Canon Powershot G7 X's maximum shutter speed is 30 seconds and there's a Bulb mode too, which is great news if you're seriously interested in night photography. The shot below was taken using a shutter speed of 30 seconds at ISO 125.

Night	Night (100% Crop)

Anti Shake

The Canon Powershot G7 X has an anti-shake mechanism, which allows you to take sharp photos at slower shutter speeds than other digital cameras. To test this, we took 2 handheld shots of the same subject with the same settings. The first shot was taken with anti shake turned off, the second with it turned on.

Shutter Speed / Focal Length	Anti-Shake Off (100% Crop)	Anti-Shake On (100% Crop)
1/10th sec / 24mm
1/10th sec / 100mm

Dynamic Range Correction

The Dynamic Range Correction mode automatically takes three exposures of the same scene at different settings, then combines them in-camera to create a single image with greater dynamic range. Note that you need to mount the G7 X on a tripod or stable surface to avoid camera-shake.

Off	Auto
200%

Shadow Correction

The Shadow Correction mode improves the shadow areas of the image without impacting on the highlights.

Conclusion

The new Canon PowerShot G7 X is an excellent pocket camera for enthusiast photographers, offering a wealth of options for shooting both still and video, excellent image quality, speedy auto-focusing, intuitive and configurable handling, and solid construction. It can't quite match the bigger and heavier G1 X Mk II in terms of performance at higher ISO speeds, but it does offer most of that camera's functionality in a smaller package, and even out-performs it in some areas.

In terms of the direct competition, the Canon PowerShot G7 X has definitely made a big leap forwards. Compared to the very popular Sony Cyber-shot RX100 Mk III, it's a very close-run thing, with the lack of a viewfinder (or any way of fitting an external one) on the G7 X being the biggest single reason to choose the Sony model for the keen photographer. If you don't need this feature, then the touchscreen capabilities of the G7 X are very compelling, as is the longer lens range, although the Sony RX100 Mk III's screen can be tilted both up and down. For us, the built-in EVF gives the Sony model the edge, but your mileage may vary according to which features you most value. Both are equally worthy of consideration.

The G7 X's image quality is excellent for a compact camera thanks to the 1-inch sensor that lies at its heart. If you've ever wanted DSLR-like pictures from a fixed-lens camera, then look no further than the G7 X, with its fast f/1.8-2.8 lens creating very nice bokeh at both ends of the versatile zoom range when shooting wide-open. Sure, it still can't match a DSLR or an APS-C equipped compact system camera at the higher ISO speeds, but ISO 100-1600 is eminently usable with 3200 as a backup, not something that you can say about many compacts.

In terms of build quality and handling, the Canon PowerShot G7 X gets most things right, offering a reassuringly rugged metal chassis and a plethora of customisable controls, including the lens control ring and exposure compensation dial, while the tilting touchscreen LCD, folding pop-up flash and 31-point AF system are all great features.

Canon have definitely caught up with the competition with the launch of the PowerShot G7 X. It offers the best balance between portability and functionality of any PowerShot camera to date, and is a serious rival to the Sony Cyber-shot RX100 Mk III. Highly Recommended!
