Canon G1 X Mark II vs Nikon D40X
The Canon PowerShot G1 X Mark II and the Nikon D40X are two digital cameras that were officially introduced, respectively, in February 2014 and March 2007. The G1X Mark II is a fixed lens compact, while the D40X is a DSLR. The cameras are based on an 1.5-inch (G1X Mark II) and an APS-C (D40X) sensor. The Canon has a resolution of 13 megapixels, whereas the Nikon provides 10 MP.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.
Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot G1 X Mark II and the Nikon D40X? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.
The physical size and weight of the Canon G1 X Mark II and the Nikon D40X are illustrated in the side-by-side display below. 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 dimensions are rounded to the nearest millimeter.
The D40X can be obtained in two different colors (black, silver), while the G1X Mark II is only available in black.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D40X is notably larger (36 percent) than the Canon G1 X Mark II. In this context, it is worth noting that neither the G1X Mark II nor the D40X are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G1X Mark II has a lens built in, whereas the D40X is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the D40X and their specifications in the Nikon Lens Catalog.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

Any camera decision will naturally be influenced heavily by the price. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. 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.
The size of the sensor inside a digital camera is one of the key determinants of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have richer color-depth than smaller pixels in a sensor of the same technological generation. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its 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 Mark II features an 1.5-inch sensor and the Nikon D40X an APS-C sensor. The sensor area in the D40X is 42 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 Mark II has a native 4:3 aspect ratio, while the one in the D40X offers a 3:2 aspect.
Despite having a smaller sensor, the Canon G1 X Mark II offers a higher resolution of 13 megapixels, compared with 10 MP of the Nikon D40X. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 4.49μm versus 6.11μm for the D40X). However, it should be noted that the G1X Mark II is much more recent (by 6 years and 11 months) than the D40X, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.
The resolution advantage of the Canon G1 X Mark II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G1X Mark II for good quality output (200 dots per inch) amounts to 20.8 x 15.6 inches or 52.8 x 39.6 cm, for very good quality (250 dpi) 16.6 x 12.5 inches or 42.3 x 31.7 cm, and for excellent quality (300 dpi) 13.9 x 10.4 inches or 35.2 x 26.4 cm. The corresponding values for the Nikon D40X are 19.4 x 13 inches or 49.2 x 32.9 cm for good quality, 15.5 x 10.4 inches or 39.3 x 26.3 cm for very good quality, and 12.9 x 8.6 inches or 32.8 x 21.9 cm for excellent quality prints.
The Canon PowerShot G1 X Mark II has a native sensitivity range from ISO 100 to ISO 12800. The corresponding ISO settings for the Nikon D40X are ISO 100 to ISO 1600, with the possibility to increase the ISO range to 100-3200.
In terms of underlying technology, the G1X Mark II is build around a CMOS sensor, while the D40X uses a CCD imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. Of the two cameras under consideration, the D40X 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 0.9 bits higher color depth, 0.6 EV in additional dynamic range, and 0.2 stops of reduced low light sensitivity. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. The G1X Mark II indeed provides movie recording capabilities, while the D40X does not. The highest resolution format that the G1X Mark II can use is 1080/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the D40X has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the G1X Mark II relies on live view and the rear LCD for framing. That said, the G1X Mark II can be equipped with an optional viewfinder – the EVF-DC1. The following table reports on some other key feature differences and similarities of the Canon G1 X Mark II, the Nikon D40X, and comparable cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The G1X Mark II has a touchscreen, while the D40X has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The G1X Mark II has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the D40X does not have a selfie-screen.
The Canon G1 X Mark II has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.
The G1X Mark II writes its imaging data to SDXC cards, while the D40X uses SDHC cards. The G1X Mark II supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the D40X cannot take advantage of Ultra High Speed SD cards.
For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Canon PowerShot G1 X Mark II and Nikon D40X and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the G1X Mark II offers wifi support, while the D40X does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
Both the G1X Mark II and the D40X have been discontinued, but can regularly be found used on ebay. The D40X was replaced by the Nikon D60 , while the G1X Mark II was followed by the Canon G1 X Mark III. Further information on the features and operation of the G1X Mark II and D40X can be found, respectively, in the Canon G1 X Mark II Manual (free pdf) or the online Nikon D40X Manual.
So how do things add up? Is the Canon G1 X Mark II better than the Nikon D40X or vice versa? Below is a summary of the relative strengths of each of the two contestants.
Arguments in favor of the Canon PowerShot G1 X Mark II:
- More detail: Offers more megapixels (13 vs 10MP) with a 12% higher linear resolution.
- Broader imaging potential: Can record not only still images but also 1080/30p movies.
- Larger screen: Has a bigger rear LCD (3.0" vs 2.5") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (1040k vs 230k dots).
- More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
- Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- Faster burst: Shoots at higher frequency (5.2 vs 3 flaps/sec) to capture the decisive moment.
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- Ready to shoot: Comes with a built-in lens, while the D40X requires a separate lens.
- More compact: Is smaller (116x74mm vs 124x94mm) and thus needs less room in the bag.
- Sharper images: Has hand-shake reducing image stabilization built-in.
- Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
- Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
- Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
- More modern: Reflects 6 years and 11 months of technical progress since the D40X launch.
Reasons to prefer the Nikon D40X:
- 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 (0.6 EV of extra DR).
- Easier framing: Has an optical viewfinder for image composition and settings control.
- More flexible: Makes it possible to change lenses and thus to use specialty optics.
- Longer lasting: Gets more shots (520 versus 240) out of a single battery charge.
- More heavily discounted: Has been around for much longer (launched in March 2007).
If the count of relative strengths (bullet points above) is taken as a measure, the G1X Mark II is the clear winner of the match-up (16 : 6 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera. A professional wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports shooter. Hence, the decision which camera is best and worth buying is often a very personal one.
How about other alternatives? Do the specifications of the Canon G1 X Mark II and the Nikon D40X place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera and Best DSLR Camera listings whether the two cameras rank among the cream of the crop.
In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the G1X Mark II or the D40X. 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 hands-on reviews by experts are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.

The review scores listed above should be treated with care, 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
