Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon 1 J4 and the Nikon Coolpix P900? 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 Nikon 1 J4 and the Nikon P900 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth measures are rounded to the nearest millimeter.

The J4 can be obtained in four different colors (black, silver, orange, white), while the P900 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 P900 is considerably larger (140 percent) than the Nikon 1 J4. In this context, it is worth noting that neither the J4 nor the P900 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the P900 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 power pack in the P900 can be charged via the USB port, which can be very convenient when travelling.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

The price is, of course, an important factor in any camera decision. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. 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 imaging sensor is a crucial determinant 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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better isolate a subject from the 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 Nikon 1 J4 features an one-inch sensor and the Nikon P900 a 1/2.3-inch sensor. The sensor area in the P900 is 76 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 5.6. The sensor in the J4 has a native 3:2 aspect ratio, while the one in the P900 offers a 4:3 aspect.

With 18.2MP, the J4 offers a higher resolution than the P900 (15.9MP), but the J4 nevertheless has larger individual pixels (pixel pitch of 2.52μm versus 1.33μm for the P900) due to its larger sensor. However, the P900 is a somewhat more recent model (by 10 months) than the J4, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels. 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 Nikon 1 J4 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the J4 for good quality output (200 dots per inch) amounts to 26.2 x 17.4 inches or 66.4 x 44.3 cm, for very good quality (250 dpi) 20.9 x 14 inches or 53.2 x 35.4 cm, and for excellent quality (300 dpi) 17.4 x 11.6 inches or 44.3 x 29.5 cm. The corresponding values for the Nikon P900 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 J4 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Nikon 1 J4 has a native sensitivity range from ISO 160 to ISO 12800. The corresponding ISO settings for the Nikon Coolpix P900 are ISO 100 to ISO 6400, with the possibility to increase the ISO range to 100-12800.

In terms of underlying technology, the J4 is build around a CMOS sensor, while the P900 uses a BSI-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 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 cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, and both provide the same movie specifications (1080/60p).

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the P900 has an electronic viewfinder (921k dots), which can be very helpful when shooting in bright sunlight. In contrast, the J4 relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Nikon 1 J4, the Nikon P900, and comparable 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 P900 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 Nikon P900 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.

The J4 writes its imaging data to micro SDXC cards, while the P900 uses SDXC cards. The J4 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the P900 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 Nikon 1 J4 and Nikon Coolpix P900 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Travel and landscape photographers will find it useful that the P900 has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.

Both the J4 and the P900 have been discontinued, but can regularly be found used on ebay. The J4 was replaced by the Nikon 1 J5, while the P900 was followed by the Nikon P950. Further information on the features and operation of the J4 and P900 can be found, respectively, in the Nikon 1 J4 Manual (free pdf) or the online Nikon P900 Manual.

Review summary

So what is the bottom line? Is the Nikon 1 J4 better than the Nikon P900 or vice versa? The listing below highlights the relative strengths of the two models.

Arguments in favor of the Nikon 1 J4:

• More detail: Offers more megapixels (18.2 vs 15.9MP) with a 9% higher linear resolution.
• 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 live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
• More detailed LCD: Has a higher resolution rear screen (1037k vs 921k dots).
• Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
• Faster burst: Shoots at higher frequency (60 vs 7 flaps/sec) to capture the decisive moment.
• Less disturbing: Has an electronic shutter option for completely silent shooting.
• More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
• More compact: Is smaller (100x60mm vs 140x103mm) and thus needs less room in the bag.
• 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).

Reasons to prefer the Nikon Coolpix P900:

• 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.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• Ready to shoot: Has an integrated lens, whereas the J4 necessitates an extra lens.
• Longer lasting: Gets more shots (360 versus 300) out of a single battery charge.
• Easier travel charging: Can be conveniently charged via its USB port.
• Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
• Easier geotagging: Features an internal GPS sensor to log localization data.
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• More modern: Was introduced somewhat (10 months) more recently.

If the count of individual advantages (bullet points above) is taken as a guide, the J4 emerges as the winner of the contest (14 : 11 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 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 Nikon 1 J4 and the Nikon P900 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best Superzoom Camera listings 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 says little about, for example, the shooting experience and imaging performance of the J4 and the P900 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 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.

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. Thus, a score needs to be put into the context of the launch date and the launch price 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
