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. The L840 was launched at a markedly lower price (by 77 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.
The size of the imaging sensor is a crucial determinant of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and 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 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 III features an APS-C sensor and the Nikon L840 a 1/2.3-inch sensor. The sensor area in the L840 is 92 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 5.6. The sensor in the G1X Mark III has a native 3:2 aspect ratio, while the one in the L840 offers a 4:3 aspect.
With 24MP, the G1X Mark III offers a higher resolution than the L840 (15.9MP), but the G1X Mark III nevertheless has larger individual pixels (pixel pitch of 3.72μm versus 1.33μm for the L840) due to its larger sensor. Moreover, the G1X Mark III is a much more recent model (by 2 years and 8 months) than the L840, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the L840 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Canon G1 X Mark III implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G1X Mark III for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Nikon L840 are 23 x 17.3 inches or 58.5 x 43.9 cm for good quality, 18.4 x 13.8 inches or 46.8 x 35.1 cm for very good quality, and 15.4 x 11.5 inches or 39 x 29.3 cm for excellent quality prints.
The G1X Mark III has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon PowerShot G1 X Mark III has a native sensitivity range from ISO 100 to ISO 25600. The corresponding ISO settings for the Nikon Coolpix L840 are ISO 100 to ISO 6400 (no boost).
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"). 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 are equipped with sensors that have a sufficiently high read-out speed for moving images, but the G1X Mark III provides a higher frame rate than the L840. It can shoot video footage at 1080/60p, while the Nikon is limited to 1080/60i.
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), which can be very helpful when shooting in bright sunlight. In contrast, the L840 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 Mark III and Nikon L840 in connection with corresponding information for a sample of similar cameras.

|Sony RX10 III||2359||Y||3.0||1229||tilting||n||1/2000s||14.0||Y||Y|
One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The G1X Mark III has a touchscreen, while the L840 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The G1X Mark III 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 L840 does not have a selfie-screen.
The Canon G1 X Mark III 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.
Both the G1X Mark III and the L840 have zoom lenses built in. The G1X Mark III has a 24-72mm f/2.8-5.6 optic and the L840 offers a 22.5-855mm f/3-6.5 (focal lengths in full frame equivalent terms). Hence, the Nikon provides a wider angle of view at the short end, as well as more tele-photo reach at the long end than the Canon. The G1X Mark III offers the faster maximum aperture.
Concerning the storage of imaging data, both the G1X Mark III and the L840 write their files to SDXC cards. The G1X Mark III supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the L840 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 III and Nikon Coolpix L840 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the G1X Mark III has a hotshoe, while the L840 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.
The G1X Mark III is a recent model that features in the current product line-up of Canon. In contrast, the L840 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the L840 was succeeded by the Nikon B500. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Nikon websites.

If the count of individual advantages (bullet points above) is taken as a guide, the G1X Mark III is the clear winner of the match-up (22 : 7 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.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the G1X Mark III and the L840 in practical situations. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.
This is where reviews by experts come in. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
