Introduction

Ease of Use

Measuring 123.3 x 76.5 x 105.3mm and weighing 733g including the battery and memory card, the Canon PowerShot G3 X features a dust and drip-proof metal body with a solid feel and sturdy construction. The G3 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 G3 X is most at home stored in a deep coat pocket or a small camera bag.

The Canon PowerShot G3 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 G3 X has a very handy exposure compensation dial on top, although setting the ISO speed is a rather convoluted affair. The G3 X doesn't have an optical viewfinder, although you can ad an electronic one if you wish. 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 now decided to only provide their software via download from their website.

Front of the Canon PowerShot G3 X

The Canon PowerShot G3 X's unassuming-looking front plate is dominated by the 25x, 24-600mm 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 G3 X has a front control dial, as featured on EOS DSLR cameras, which makes changing the aperture and full Manual shooting mode very straight-forward.

You use a combination of the 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. We found the rear navigation wheel on the rear a bit too thin to use precisely and quickly. In addition, the lens ring can be assigned to various different settings, including ISO speed, focus and aperture/shutter speed.

There's a large handgrip on the Canon PowerShot G3 X with a rubberised surface, which makes it easy to steady the camera, along with a textured small pad at the back for your right thumb to rest on. We did miss having a viewfinder by default though - trying to hold the G3 X at arm's length whilst using the full extent of the 25x zoom lens inevitably resulted in some missed shots due to camera-shake.

Rear of the Canon PowerShot G3 X

From left to right the G3 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 25x zoom (24-600mm equivalent on a 35mm camera), and behind this again the aforementioned control dial and a 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 G3 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 G3 X's lens has bright apertures of f/2.8 at the wide-angle end of the zoom range and f/5.6 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 G3 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 G3 X can capture JPEG shots at 5.9fps with the focus point locked at the first frame, or you can shoot continuously at 3.2fps 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, activated via the one-touch movie record button on top of the camera. The Canon PowerShot can shoot 1080p HD video quality at 1920x1080 pixels at 60fps, 30fps, 25fps or 24fps, you can adjust the aperture, shutter speed and ISO, and there's manual focus peaking too. The G3 X also boasts stereo sound courtesy of tiny microphones positioned above the lens barrel, and you can use the creative filters and the 25x 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 G3 X on a tripod or stable surface to avoid camera-shake.

The Canon PowerShot G3 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 and down by 45° for overhead shots. The LCD is a 3.2 inch monitor with 3:2 aspect ratio and a very high resolution of 1.62 million dots.

The Canon PowerShot G3 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 rear of the G3 X is a button for quickly connecting to a previously paired smartphone or tablet. The G3 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 G3 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 G3 X to an iOS or Android device.

Top of the Canon PowerShot G3 X

The G3 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 G3 X doesn't compare well with rivals that offer this feature, although it does side-step the issue of negatively affecting battery life. The G3 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, the Shortcut button can be configured to one of 22 different functions. To the right are the AEL and Focus Area buttons, with the Playback and Menu buttons below. 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.

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 ISO speed, choosing from the on-board flash settings, toggling between the One Shot and Continuous AF modes, and activating normal or 5cm macro focus modes. The G3 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 G3 X

At its centre is the Q//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.

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 acceptable at around 300 shots from a full charge.

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 G3 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 G3 X handled chromatic aberrations fairly well, with some 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 G3 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 extract more detail from the shadow and highlight areas.

The Canon PowerShot G3 X's 25x zoom lens offers a very versatile focal range, as illustrated by these examples:

24mm	600mm

Sharpening

Here are two 100% crops which have been Saved as Web - Quality 50 in Photoshop. The right-hand image has had some sharpening applied in Photoshop. The out-of-the camera images are a little soft at the default sharpening setting. You can change the in-camera sharpening level if you don't like the default look.

Original (100% Crop)	Sharpened (100% Crop)

File Quality

The Panasonic Lumix DMC-LX100 has 2 different JPEG image quality settings available, with SuperFine being the highest quality option. Here are some 100% crops which show the quality of the various options, with the file size shown in brackets.

SuperFine (7.61Mb) (100% Crop)	Fine (5.01Mb) (100% Crop)
RAW (24.1Mb) (100% Crop)

Chromatic Aberrations

The Canon PowerShot G3 X handled chromatic aberrations fairly well during the review, with some green and 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 G3 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).

Macro	Macro (100% Crop)

Flash

The flash settings on the Canon Powershot G3 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 G3 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 G3 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)
1/6th sec / 24mm
1/8th sec / 600mm

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 G3 X on a tripod or stable surface to avoid camera-shake.

Off	Auto

Conclusion

The new Canon PowerShot G3 X is a solid super-zoom camera for enthusiast photographers, offering a wealth of options for shooting both stills and video, excellent image quality, speedy auto-focusing, intuitive and configurable handling, and solid construction. Unfortunately, it's rather ham-strung by the strange omission of a built-in viewfinder - trying to hold the Canon PowerShot G3 X at arm's length whilst using the full extent of the 25x zoom lens results in too many misses due to camerashake. Sure, you can add the expensive optional electronic viewfinder, but the G3 X's main rivals (the Panasonic Lumix FZ1000 and Sony CyberShot DSC-RX10) both feature a built-in viewfinder and cost less than the out-of-the-box G3 X.

The G3 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 G3 X, with its fast f/2.8-5.6 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 too many compacts.

In terms of build quality and handling, the Canon PowerShot G3 X again gets most things right, offering a reassuringly rugged dust and drip-proof metal chassis and a plethora of customisable controls, including the lens control ring. command dial and exposure compensation dial, while the tilting touchscreen LCD, folding pop-up flash and 31-point AF system are all great features.

The Canon PowerShot G3 X is almost the perfect super-zoom camera for more experienced photographers, but the decision not to include a built-in viewfinder turns the G3 X into a near-miss...
