Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot SX70 HS 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 SX70 and the Nikon L840 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth dimensions are rounded to the nearest millimeter.

The L840 can be obtained in two different colors (black, red), while the SX70 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 smaller (24 percent) than the Canon SX70. Moreover, the L840 is markedly lighter (12 percent) than the SX70. In this context, it is worth noting that neither the SX70 nor the L840 are weather-sealed.

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 SX70, 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 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 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.

Both cameras under consideration feature a 1/2.3-inch sensor and have a format factor (sometimes also referred to as "crop factor") of 5.6. Within the spectrum of camera sensors, this places the review cameras among the smaller-sensor digicams that favor affordability and compact design. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

While the two cameras under review share the same sensor size, the SX70 offers a higher resolution of 20.2 megapixels, compared with 15.9 MP of the L840. This megapixels advantage translates into a 13 percent gain in linear resolution. On the other hand, these sensor specs imply that the SX70 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 1.18μm versus 1.33μm for the L840). In this context, it should be noted, however, that the SX70 is much more recent (by 3 years and 7 months) than the L840, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size. Coming back to sensor resolution, it should be mentioned that neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.

The resolution advantage of the Canon SX70 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the SX70 for good quality output (200 dots per inch) amounts to 25.9 x 19.4 inches or 65.8 x 49.4 cm, for very good quality (250 dpi) 20.7 x 15.6 inches or 52.7 x 39.5 cm, and for excellent quality (300 dpi) 17.3 x 13 inches or 43.9 x 32.9 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 Canon PowerShot SX70 HS has a native sensitivity range from ISO 100 to ISO 3200. The corresponding ISO settings for the Nikon Coolpix L840 are ISO 100 to ISO 6400 (no boost).

In terms of underlying technology, the SX70 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.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 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 also of capturing video footage. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the SX70 provides a higher video resolution than the L840. It can shoot video footage at 4K/30p, 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 SX70 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 following table reports on some other key feature differences and similarities of the Canon SX70, the Nikon L840, and comparable cameras.

Both the SX70 and the L840 have zoom lenses built in. The SX70 has a 21-1365mm f/3.4-6.5 optic and the L840 offers a 22.5-855mm f/3.0-6.5 (focal lengths in full frame equivalent terms). Hence, the Canon provides a wider angle of view at the short end, as well as more tele-photo reach at the long end than the Nikon. The L840 offers the faster maximum aperture.

Concerning the storage of imaging data, both the SX70 and the L840 write their files to SDXC cards. The SX70 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 SX70 HS 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 SX70 has a microphone port, which is missing on the L840. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.

The SX70 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 features and operation of the SX70 and L840 can be found, respectively, in the Canon SX70 Manual (free pdf) or the online Nikon L840 Manual.

Review summary

So what is the bottom line? Is there a clear favorite between the Canon SX70 and the Nikon L840? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

Arguments in favor of the Canon PowerShot SX70 HS:

• More detail: Offers more megapixels (20.2 vs 15.9MP) with a 13% higher linear resolution.
• Better video: Provides higher definition movie capture (4K/30p vs 1080/60i).
• Better sound: Can connect to an external microphone for higher quality sound recording.
• Easier framing: Has an electronic viewfinder for image composition and settings control.
• More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Faster burst: Shoots at higher frequency (10 vs 7.4 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.
• Easier wireless transfer: Supports Bluetooth for image sharing without cables.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More modern: Reflects 3 years and 7 months of technical progress since the L840 launch.

Reasons to prefer the Nikon Coolpix L840:

• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
• Better light gathering: Has a lens with a wider maximum aperture (f/3.0 vs f/3.4).
• More compact: Is smaller (113x78mm vs 127x91mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 70g or 12 percent) and is thus easier to take along.
• Longer lasting: Gets more shots (590 versus 325) 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 heavily discounted: Has been around for much longer (launched in February 2015).

If the number of relative strengths (bullet points above) is taken as a guide, the SX70 is the clear winner of the match-up (12 : 8 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape 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 SX70 and the Nikon L840 place the cameras among the top in their class? Find out in the latest Best Superzoom Camera listing 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 partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the SX70 or the L840. 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.

Expert reviews

This is why hands-on reviews by experts are important. 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 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.
