Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot G16 and the Nikon Coolpix L840? 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.

Body comparison

An illustration of the physical size and weight of the Canon G16 and the Nikon L840 is provided 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 measures are rounded to the nearest millimeter.

The L840 can be obtained in two different colors (black, red), while the G16 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 L840 is notably larger (6 percent) than the Canon G16. Moreover, the L840 is substantially heavier (51 percent) than the G16. In this context, it is worth noting that neither the G16 nor the L840 are weather-sealed.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

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 46 percent) than the G16, 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 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon G16 features a 1/1.7-inch sensor and the Nikon L840 a 1/2.3-inch sensor. The sensor area in the L840 is 33 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 4.65 and 5.6. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

Despite having a smaller sensor, the L840 offers a higher resolution of 15.9 megapixels, compared with 12 MP of the G16. 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 1.33μm versus 1.87μm for the G16). However, it should be noted that the L840 is a somewhat more recent model (by 1 year and 5 months) than the G16, and its sensor might have benefitted from technological advances during this time that partly offset its pixel-size disadvantage. 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 Nikon L840 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the L840 for good quality output (200 dots per inch) amounts to 23 x 17.3 inches or 58.5 x 43.9 cm, for very good quality (250 dpi) 18.4 x 13.8 inches or 46.8 x 35.1 cm, and for excellent quality (300 dpi) 15.4 x 11.5 inches or 39 x 29.3 cm. The corresponding values for the Canon G16 are 20 x 15 inches or 50.8 x 38.1 cm for good quality, 16 x 12 inches or 40.6 x 30.5 cm for very good quality, and 13.3 x 10 inches or 33.9 x 25.4 cm for excellent quality prints.

The Canon PowerShot G16 has a native sensitivity range from ISO 80 to ISO 12800. The corresponding ISO settings for the Nikon Coolpix L840 are ISO 100 to ISO 6400 (no boost).

In terms of underlying technology, the G16 is build around a BSI-CMOS sensor, while the L840 uses a CMOS 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. 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. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the G16 provides a higher frame rate than the L840. It can shoot video footage at 1080/60p, while the Nikon is limited to 1080/60i.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the G16 has an optical viewfinder, which can be very useful 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 G16 and Nikon L840 in connection with corresponding information for a sample of similar cameras.

The Canon G16 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 G16 and the L840 have zoom lenses built in. The G16 has a 28-140mm f/1.8-2.8 optic and the L840 offers a 22.5-855mm f/3.0-6.5 (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 G16 offers the faster maximum aperture.

Concerning the storage of imaging data, both the G16 and the L840 write their files to SDXC cards. The G16 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.

Connectivity comparison

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 G16 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 G16 has a hotshoe, while the L840 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

Both the G16 and the L840 have been discontinued, but can regularly be found used on ebay. The L840 was replaced by the Nikon B500, while the G16 does not have a direct successor. Further information on the features and operation of the G16 and L840 can be found, respectively, in the Canon G16 Manual (free pdf) or the online Nikon L840 Manual.

Review summary

So how do things add up? Is there a clear favorite between the Canon G16 and the Nikon L840? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

Advantages of the Canon PowerShot G16:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
• Richer colors: The pixel size advantage translates into images with better, more accurate colors.
• More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
• Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
• Better video: Provides higher movie framerates (1080/60p versus 1080/60i).
• Easier framing: Has an optical viewfinder for image composition and settings control.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• Better light gathering: Has a lens with a wider maximum aperture (f/1.8 vs f/3.0).
• Less heavy: Is lighter (by 182g or 34 percent) and hence easier to carry around.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More heavily discounted: Has been on the market for longer (launched in August 2013).

Reasons to prefer the Nikon Coolpix L840:

• More detail: Has more megapixels (15.9 vs 12MP), which boosts linear resolution by 15%.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
• Faster burst: Shoots at higher frequency (7.4 vs 2.2 flaps/sec) to capture the decisive moment.
• Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
• More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
• Longer lasting: Gets more shots (590 versus 360) out of a single battery charge.
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• More affordable: Was introduced into a lower priced category (46 percent cheaper at launch).
• More modern: Was introduced somewhat (1 year and 5 months) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the G16 emerges as the winner of the contest (13 : 10 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 G16 and the Nikon L840 place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera and Best Superzoom 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 says little about, for example, the shooting experience and imaging performance of the G16 and the L840 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.

Expert reviews

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 (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 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.
