Canon G1 X versus Canon G1 X Mark III

The Canon PowerShot G1 X and the Canon PowerShot G1 X Mark III are two enthusiast cameras that were revealed to the public, respectively, in January 2012 and October 2017. Both the G1X and the G1X Mark III are fixed lens compact cameras that are based on an 1.5-inch (G1X) and an APS-C sensor. The G1X has a resolution of 14.2 megapixel, whereas the G1X Mark III provides 24 MP.

Body comparison

An illustration of the physical size and weight of the Canon G1 X and the Canon G1 X Mark III is provided in the side-by-side display below. Three consecutive perspectives from the front, the top, and the back are presented. All size dimensions are rounded to the nearest millimeter. If you prefer, you can also use the toggle button to switch to a comparison in percentage terms (in this case, the camera on the left side – the G1X – represents the basis for the calculations across all the size and weight measures).

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The G1X was launched at a markedly lower price (by 38 percent) than the G1X Mark III, which puts it into a different market segment. 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

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to 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 features an 1.5-inch sensor and the Canon G1 X Mark III an APS-C sensor. The sensor area in the G1X Mark III is 27 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.85 and 1.5. The sensor in the G1X has a native 4:3 aspect ratio, while the one in the G1X Mark III offers a 3:2 aspect.

Sensor size

With 24MP, the G1X Mark III offers a higher resolution than the G1X (14.2MP), but the G1X Mark III has smaller individual pixels (pixel pitch of 3.72μm versus 4.30μm for the G1X). Yet, the G1X Mark III is a much more recent model (by 5 years and 9 months) than the G1X, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the G1X Mark III provides a faster frame rate than the G1X. It can shoot movie footage at 1080/60p, while the G1X is limited to 1080/24p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the G1X Mark III has an electronic viewfinder (2360k dots), while the G1X has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The table below summarizes some of the other core capabilities of the Canon G1 X and Canon G1 X Mark III in connection with corresponding information for a sample of similar cameras. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

Both the G1X and the G1X Mark III have zoom lenses build in. The G1X has a 28-112mm f/2.8-5.8 optic and the G1X Mark III offers a 24-72mm f/2.8-5.6 (focal lengths in full frame equivalent terms). Hence, the G1X Mark III provides a wider angle of view at the short end than the G1X, but less tele-photo reach at the long end. Both cameras offer the same maximum aperture.

The G1X Mark III is a current model that online retailers, such as amazon, will have in stock. In contrast, the G1X has been discontinued (but it can be found pre-owned on ebay). As a replacement in the same line of cameras, the G1X was succeeded by the Canon G1X Mark II.

Summary

So how do things add up? Is there a clear favorite between the Canon G1 X and the Canon G1 X? A synthesis of the relative strong points of each of the models is listed below.


Advantages of the Canon PowerShot G1 X:

  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • Faster shutter: Has higher mechanical shutter speed (4000/sec vs 2000/sec) to freeze action.
  • More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
  • Longer lasting: Can take more shots (250 versus 200) on a single battery charge.
  • More affordable: Was introduced into a lower priced category (38 percent cheaper at launch).
  • More heavily discounted: Has been available for much longer (launched in January 2012).

Reasons to prefer the Canon PowerShot G1 X Mark III:

  • More detail: Has more megapixels (24 vs 14.2MP), which boosts linear resolution by 33%.
  • Better image quality: Is equipped with a larger and more technologically advanced sensor.
  • Better video: Provides higher movie framerates (1080/60p vs 1080/24p).
  • More framing info: Has an electronic viewfinder that displays shooting data.
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 922k dots).
  • More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • Faster burst: Shoots at higher frequency (9 vs 1.9 flaps/sec) to capture the decisive moment.
  • Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
  • Less heavy: Has a lower weight (by 135g or 25 percent) and is thus easier to take along.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • More modern: Reflects 5 years and 9 months of technical progress since the G1X launch.

If the count of relative strengths (bullet points above) is taken as a measure, the G1X Mark III is the clear winner of the contest (12 : 6 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.

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the G1X and the G1X Mark III in practical situations. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased. This is where reviews by experts come in. The following table reports the overall rankings of the cameras as published by some of the major camera review sites. The detailed reviews can be accessed, respectively, on the websites of cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
