Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot SX420 IS and the Nikon 1 J4? 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 side-by-side display below illustrates the physical size and weight of the Canon SX420 and the Nikon 1 J4. 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 SX420 can be obtained in two different colors (black, red), while the J4 is available in four color-versions (black, silver, orange, white).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon 1 J4 is notably smaller (16 percent) than the Canon SX420. In this context, it is worth noting that neither the SX420 nor the J4 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the SX420 has a lens built in, whereas the J4 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you want to switch the focus of the display and review another camera pair, you can move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The SX420 was launched at a lower price than the J4, despite having a lens built in. 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.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants 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.

Of the two cameras under consideration, the Canon SX420 features a 1/2.3-inch sensor and the Nikon 1 J4 an one-inch sensor. The sensor area in the J4 is 314 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 5.6 and 2.7. The sensor in the SX420 has a native 4:3 aspect ratio, while the one in the J4 offers a 3:2 aspect.

Despite having a smaller sensor, the Canon SX420 offers a higher resolution of 19.9 megapixels, compared with 18.2 MP of the Nikon 1 J4. 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 1.19μm versus 2.52μm for the J4). However, it should be noted that the SX420 is a somewhat more recent model (by 1 year and 8 months) than the J4, 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 neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.

The J4 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Canon PowerShot SX420 IS has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Nikon 1 J4 are ISO 160 to ISO 12800 (no boost).

In terms of underlying technology, the SX420 is build around a CCD sensor, while the J4 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 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 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 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 J4 provides a better video resolution than the SX420. It can shoot movie footage at 1080/60p, while the Canon is limited to 720/25p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The SX420 and the J4 are similar in the sense that neither of the two has a viewfinder. The images are, thus, framed using live view on the rear LCD. The table below summarizes some of the other core capabilities of the Canon SX420 and Nikon 1 J4 in connection with corresponding information for a sample of similar cameras.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The J4 has a touchscreen, while the SX420 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the J4 is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).

The SX420 writes its imaging data to SDXC cards, while the J4 uses micro SDXC cards. The J4 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the SX420 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 SX420 IS and Nikon 1 J4 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the SX420 and the J4 have been discontinued, but can regularly be found used on ebay. The J4 was replaced by the Nikon 1 J5, while the SX420 was followed by the Canon SX430. Further information on the features and operation of the SX420 and J4 can be found, respectively, in the Canon SX420 Manual (free pdf) or the online Nikon 1 J4 Manual.

Review summary

So how do things add up? Is the Canon SX420 better than the Nikon 1 J4 or vice versa? Below is a summary of the relative strengths of each of the two contestants.

Reasons to prefer the Canon PowerShot SX420 IS:

• Ready to shoot: Has a lens built-in, whereas the J4 requires a separate lens.
• Sharper images: Has hand-shake reducing image stabilization built-in.
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• More affordable: Was introduced at a lower price, despite coming with a built-in lens.
• More modern: Is somewhat more recent (announced 1 year and 8 months after the J4).

Advantages of the Nikon 1 J4:

• 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 definition movie capture (1080/60p vs 720/25p).
• Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
• More detailed LCD: Has a higher resolution rear screen (1037k vs 230k dots).
• Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
• Faster burst: Shoots at higher frequency (60 vs 0.5 flaps/sec) to capture the decisive moment.
• Less disturbing: Has an electronic shutter option for completely silent shooting.
• More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
• More compact: Is smaller (100x60mm vs 104x69mm) and will fit more readily into a bag.
• Longer lasting: Gets more shots (300 versus 195) out of a single battery charge.
• 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 April 2014).

If the count of individual advantages (bullet points above) is taken as a guide, the J4 is the clear winner of the contest (15 : 5 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 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 SX420 and the Nikon 1 J4 place the cameras among the top in their class? Find out in the latest Best Superzoom Camera and Best Mirrorless Interchangeable Lens 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 remains incomplete and does no justice, for example, to the way the SX420 or the J4 perform in practice. 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 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.

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
