Any camera purchase will naturally be influenced heavily by the price. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The G1X Mark II was launched at a somewhat lower price (by 20 percent) than the G3X, which makes it more attractive for photographers on a tight budget. Usually, retail prices stay at first close to the launch price, but after several months, discounts become available. Later in the product cycle and, in particular, when the replacement model is about to appear, further discounting and stock clearance sales often push the camera price considerably down. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

 

Sensor comparison: Canon G1 X Mark II vs Canon G3 X

The size of the imaging sensor is a crucial determinant of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units in a sensor of the same technological generation. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better isolate a subject from the background. On the downside, larger sensors tend to be more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon G1 X Mark II features an 1.5-inch sensor and the Canon G3 X an one-inch sensor. The sensor area in the G3X is 56 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.85 and 2.7. The sensor in the G1X Mark II has a native 4:3 aspect ratio, while the one in the G3X offers a 3:2 aspect.

Canon G1 X Mark II and Canon G3 X sensor measures

Despite having a smaller sensor, the G3X offers a higher resolution of 20 megapixel, compared with 13 MP of the G1X Mark II. This megapixel advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 2.41μm versus 4.49μm for the G1X Mark II). However, it should be noted that the G3X is a somewhat more recent model (by 1 year and 4 months) than the G1X Mark II, and its sensor might have benefitted from technological advances during this time that partly offset its pixel-size disadvantage.

G1X Mark II versus G3X MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). Of the two cameras under consideration, the G3X has a markedly higher DXO score than the G1X Mark II (overall score 5 points higher), which will translate into better image quality. The advantage is based on 0.1 bits lower color depth, 1.5 EV in additional dynamic range, 0.2 stops of reduced low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the G3X provides a faster frame rate than the G1X Mark II. It can shoot movie footage at 1080/60p, while the G1X Mark II is limited to 1080/30p.

 

Feature comparison: Canon G1 X Mark II vs Canon G3 X

Apart from body and sensor, cameras can and do differ across a range of features. The G1X Mark II and the G3X are similar in the sense that neither of the two has a viewfinder. The images are, thus, framed using live view on the rear LCD. However, optional viewfinders – the EVF-DC1 for the G1X Mark II and the EVF-DC1 for the G3X – are available as accessories. The following table reports on some other key feature differences and similarities of the Canon G1 X Mark II, the Canon G3 X, and comparable cameras. The full specs-sheets can be found in the camera manual or in the dpreview camera hub.

Review summary: Canon G1 X Mark II vs Canon G3 X

So what conclusions can be drawn? Which of the two cameras – the Canon G1 X Mark II or the Canon G3 X – has the upper hand? Below is a summary of the relative strengths of each of the two contestants.


Reasons to prefer the Canon PowerShot G1 X Mark II:

  • Faster shutter: Has higher mechanical shutter speed (4000/sec vs 2000/sec) to freeze action.
  • Better light gathering: Has a lens with a wider maximum aperture (f/2.0 vs f/2.8).
  • Less heavy: Is lighter (by 180g or 25 percent) and hence easier to carry around.
  • More affordable: Was introduced into a lower priced segment (20 percent cheaper at launch).
  • More heavily discounted: Has been on the market for longer (launched in February 2014).


Arguments in favor of the Canon PowerShot G3 X:

  • More detail: Has more megapixels (20 vs 13MP), which boosts linear resolution by 26%.
  • Better image quality: Scores markedly higher (5 points) in the DXO overall evaluation.
  • More dynamic range: Captures a broader range of light and dark details (1.5 EV of extra DR).
  • Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
  • Better sound: Can connect to an external microphone for higher quality sound recording.
  • Better sound control: Has a headphone port that enables audio monitoring while recording.
  • Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (1620k vs 1040k dots).
  • Faster burst: Shoots at higher frequency (5.9 vs 5.2 flaps/sec) to capture the decisive moment.
  • More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
  • Longer lasting: Gets more shots (300 versus 240) out of a single battery charge.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • More modern: Was introduced somewhat (1 year and 4 months) more recently.

If the number of relative strengths (bullet points above) is taken as a guide, the G3X is the clear winner of the contest (13 : 5 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision on a new camera.

G1X Mark II 05:13 G3X

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the G1X Mark II or the G3X. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable. This is why expert reviews are important. The table below summarizes the assessments of some of the best known camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
