Canon G1 X Mark II vs Nikon D40
The Canon PowerShot G1 X Mark II and the Nikon D40 are two digital cameras that were officially introduced, respectively, in February 2014 and November 2006. The G1X Mark II is a fixed lens compact, while the D40 is a DSLR. The cameras are based on an 1.5-inch (G1X Mark II) and an APS-C (D40) sensor. The Canon has a resolution of 13 megapixels, whereas the Nikon provides 6 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 D40? 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 D40 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth measures are rounded to the nearest millimeter.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D40 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 D40 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 D40 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 D40 and their specifications in the Nikon Lens Catalog.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

Any camera decision will obviously take relative prices into account. 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. 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.
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 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. 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 are more costly to manufacture and tend to 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 Nikon D40 an APS-C sensor. The sensor area in the D40 is 41 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 D40 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 6 MP of the Nikon D40. 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 7.85μm for the D40). However, it should be noted that the G1X Mark II is much more recent (by 7 years and 2 months) than the D40, 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 D40 are 15 x 10 inches or 38.2 x 25.4 cm for good quality, 12 x 8 inches or 30.6 x 20.3 cm for very good quality, and 10 x 6.7 inches or 25.5 x 16.9 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 D40 are ISO 200 to ISO 1600, with the possibility to increase the ISO range to 200-3200.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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"). The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. 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 D40 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 D40 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 table below summarizes some of the other core capabilities of the Canon G1 X Mark II and Nikon D40 in connection with corresponding information for a sample of similar 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 D40 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 D40 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 D40 uses SDHC cards. The G1X Mark II supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the D40 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 D40 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

If the count of individual advantages (bullet points above) is taken as a guide, the G1X Mark II is the clear winner of the match-up (16 : 4 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. 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 D40 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 the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the G1X Mark II or the D40 perform in practice. 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 hands-on reviews by experts are important. The adjacent summary-table relays the overall verdicts of several of the most popular camera 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.

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 comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
