Canon G1 X versus Canon G7 X

The Canon PowerShot G1 X and the Canon PowerShot G7 X are two digital cameras that were officially introduced, respectively, in January 2012 and September 2014. Both the G1X and the G7X are fixed lens compact cameras that are based on an 1.5-inch (G1X) and an one-inch (G7X) sensor. The G1X has a resolution of 14.2 megapixel, whereas the G7X provides 20 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Canon G1 X vs Canon G7 X

The side-by-side display below illustrates the physical size and weight of the Canon G1 X and the Canon G7 X. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth measures 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 camera’s price is obviously a critical decision-making factor. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The G7X was launched at a somewhat lower price (by 13 percent) than the G1X, which makes it more attractive for photographers on a tight budget. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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.

 

Sensor comparison: Canon G1 X vs Canon G7 X

The size of the sensor inside a digital camera is one of the key determinants 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 associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Canon G1 X features an 1.5-inch sensor and the Canon G7 X an one-inch sensor. The sensor area in the G7X 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 has a native 4:3 aspect ratio, while the one in the G7X offers a 3:2 aspect.

Technology-wise, the G7X uses a more advanced image processing engine (DIGIC 6) than the G1X (DIGIC 5), with benefits for noise reduction, color accuracy, and processing speed.

Canon G1 X and Canon G7 X sensor measures

Despite having a smaller sensor, the G7X offers a higher resolution of 20 megapixel, compared with 14.2 MP of the G1X. 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 4.30μm for the G1X). However, it should be noted that the G7X is much more recent (by 2 years and 8 months) than the G1X, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

G1X versus G7X MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). Of the two cameras under consideration, the G7X offers substantially better image quality than the G1X (overall score 11 points higher). The advantage is based on 1.3 bits higher color depth, 1.9 EV in additional dynamic range, 0.2 stops of reduced low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the G7X 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: Canon G1 X vs Canon G7 X

Apart from body and sensor, cameras can and do differ across a range of features. For example, the G1X has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the G7X relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Canon G1 X and Canon G7 X 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.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The G7X has a touchscreen, while the G1X has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

Both the G1X and the G7X have zoom lenses build in. The G1X has a 28-112mm f/2.8-5.8 optic and the G7X offers a 24-100mm f/1.8-2.8 (focal lengths in full frame equivalent terms). Hence, the G7X provides a wider angle of view at the short end than the G1X, but less tele-photo reach at the long end. The G7X offers the faster maximum aperture.

Both the G1X and the G7X write their imaging data to SDXC cards.

Both the G1X and the G7X have been discontinued, but can regularly be found used on eBay. The G1X was replaced by the Canon G1X Mark II, while the G7X was followed by the Canon G7 X Mark II.

Review summary: Canon G1 X vs Canon G7 X

So how do things add up? Is the Canon G1 X better than the Canon G7 X or vice versa? Below is a summary of the relative strengths of each of the two contestants.


Reasons to prefer the Canon PowerShot G1 X:

  • Easier framing: Has an optical viewfinder for image framing and settings control.
  • 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 210) on a single battery charge.
  • Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
  • More heavily discounted: Has been available for much longer (launched in January 2012).


Advantages of the Canon PowerShot G7 X:

  • More detail: Has more megapixels (20 vs 14.2MP), which boosts linear resolution by 21%.
  • Better image quality: Scores substantially higher (11 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (1.3 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (1.9 EV of extra DR).
  • Better jpgs: Has a more modern image processing engine (DIGIC 6 vs DIGIC 5).
  • Better video: Provides higher movie framerates (1080/60p versus 1080/24p).
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 922k dots).
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • Faster burst: Shoots at higher frequency (6.5 vs 1.9 flaps/sec) to capture the decisive moment.
  • Better light gathering: Has a lens with a wider maximum aperture (f/1.8 vs f/2.8).
  • Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
  • More compact: Is smaller (103x60mm vs 117x81mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 230g or 43 percent) and is thus easier to take along.
  • Easier file upload: Has wifi build in for automatic backup or image transfer to the web.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • More affordable: Was released into a lower priced segment (13 percent cheaper at launch).
  • More modern: Reflects 2 years and 8 months of technical progress since the G1X launch.

If the count of individual advantages (bullet points above) is taken as a guide, the G7X is the clear winner of the contest (17 : 6 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision.

G1X 06:17 G7X

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the G1X or the G7X handle or perform in practice. 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 why expert reviews are important.

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
