Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot SX400 IS and the Nikon Coolpix P950? 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

The physical size and weight of the Canon SX400 and the Nikon P950 are illustrated 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.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon P950 is considerably larger (115 percent) than the Canon SX400. Moreover, the P950 is substantially heavier (221 percent) than the SX400. In this context, it is worth noting that neither the SX400 nor the P950 are weather-sealed.

Concerning battery life, the SX400 gets 190 shots out of its NB-11LH battery, while the P950 can take 290 images on a single charge of its EN-EL20a power pack. The power pack in the P950 can be charged via the USB port, which can be very convenient when travelling.

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 SX400 was launched at a markedly lower price (by 69 percent) than the P950, 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. 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 tend to be more expensive and lead to bigger and heavier cameras 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.

The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 15.9 megapixels. This similarity in sensor specs implies that both the SX400 and the P950 have the same pixel density, as well as the same pixel size. It should, however, be noted that the P950 is much more recent (by 5 years and 5 months) than the SX400, and its sensor will have benefitted from technological advances during this time. 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 Canon PowerShot SX400 IS has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Nikon Coolpix P950 are ISO 100 to ISO 6400, with the possibility to increase the ISO range to 100-12800.

In terms of underlying technology, the SX400 is build around a CCD sensor, while the P950 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 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 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 P950 provides a better video resolution than the SX400. It can shoot movie footage at 4K/30p, while the Canon is limited to 720/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the P950 has an electronic viewfinder (2359k dots), which can be very helpful when shooting in bright sunlight. In contrast, the SX400 relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Canon SX400 and Nikon P950 along with similar information for a selection of comparators.

The Nikon P950 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 SX400 and the P950 have zoom lenses built in. The SX400 has a 24-720mm f/3.4-5.8 optic and the P950 offers a 24-2000mm f/2.8-6.5 (focal lengths in full frame equivalent terms). Hence, the Canon and Nikon provide the same view at the wide-angle end, but the Nikon has more tele-photo reach at the long end. The P950 offers the faster maximum aperture.

Concerning the storage of imaging data, both the SX400 and the P950 write their files to SDXC 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 SX400 IS and Nikon Coolpix P950 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the P950 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the SX400 does not provide wifi capability.

The P950 is a recent model that features in the current product line-up of Nikon. In contrast, the SX400 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the SX400 was succeeded by the Canon SX410. Further information on the features and operation of the SX400 and P950 can be found, respectively, in the Canon SX400 Manual (free pdf) or the online Nikon P950 Manual.

Review summary

So what conclusions can be drawn? Is the Canon SX400 better than the Nikon P950 or vice versa? The listing below highlights the relative strengths of the two models.

Advantages of the Canon PowerShot SX400 IS:

• More compact: Is smaller (104x69mm vs 140x110mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 692g or 69 percent) and hence easier to carry around.
• More affordable: Was introduced into a lower priced category (69 percent cheaper at launch).
• More heavily discounted: Has been available for much longer (launched in July 2014).

Arguments in favor of the Nikon Coolpix P950:

• Better video: Provides higher definition movie capture (4K/30p vs 720/30p).
• 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.
• Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (921k vs 230k dots).
• 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 shutter: Has higher mechanical shutter speed (1/4000s vs 1/1600s) to freeze action.
• Faster burst: Shoots at higher frequency (7 vs 0.8 flaps/sec) to capture the decisive moment.
• 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/2.8 vs f/3.4).
• More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
• Longer lasting: Gets more shots (290 versus 190) out of a single battery charge.
• Easier travel charging: Can be conveniently charged via its USB port.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• Easier wireless transfer: Supports Bluetooth for image sharing without cables.
• More modern: Reflects 5 years and 5 months of technical progress since the SX400 launch.

If the number of relative strengths (bullet points above) is taken as a guide, the P950 is the clear winner of the contest (18 : 4 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro 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 SX400 and the Nikon P950 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 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 SX400 and the P950 in practical situations. 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.

Expert reviews

This is why expert reviews 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.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

The review scores listed above should be treated 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
