Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.

Any camera decision will obviously take relative prices into account. 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 J4 was launched at a markedly lower price (by 54 percent) than the D7100, which puts it into a different market segment. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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 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. 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 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 D7100 an APS-C sensor. The sensor area in the D7100 is 216 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Nikon 1 J4 and Nikon D7100 sensor measures

With 24MP, the D7100 offers a higher resolution than the J4 (18.2MP), but the D7100 nevertheless has larger individual pixels (pixel pitch of 3.91μm versus 2.52μm for the J4) due to its larger sensor. However, the J4 is a somewhat more recent model (by 1 year and 1 month) than the D7100, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units. 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 D7100 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D7100 for good quality output (200 dots per inch) amounts to 30 x 20 inch or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inch or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inch or 50.8 x 33.9 cm. The corresponding values for the Nikon 1 J4 are 26.2 x 17.4 inch or 66.4 x 44.3 cm for good quality, 20.9 x 14 inch or 53.2 x 35.4 cm for very good quality, and 17.4 x 11.6 inch or 44.3 x 29.5 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 D7100 are ISO 100 to ISO 6400, with the possibility to increase the ISO range to 50-25600.

J4 versus D7100 MP

For many cameras, data on sensor performance has been reported by DXO Mark. 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"). Of the two cameras under consideration, the D7100 offers substantially better image quality than the J4 (overall score 30 points higher). The advantage is based on 3.4 bits higher color depth, 3 EV in additional dynamic range, and 1.6 stops in additional low light sensitivity. 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. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, and both provide the same movie specifications (1080/60p).

 

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the D7100 has an optical viewfinder, which can be very useful 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 D7100, and comparable cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The J4 has a touchscreen, while the D7100 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 D7100 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 D7100 uses SDXC cards. The D7100 features dual card slots, which can be very useful in case a memory card fails. In contrast, the J4 only has one slot. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.

 

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 D7100 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the J4 offers wifi support, while the D7100 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Both the J4 and the D7100 have been discontinued, but can regularly be found used on eBay. The D7100 was replaced by the Nikon D7200, while the J4 was followed by the Nikon 1 J5. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Nikon website.


Review summary

So what conclusions can be drawn? Is there a clear favorite between the Nikon 1 J4 and the Nikon D7100? Which camera is better? The listing below highlights the relative strengths of the two models.


Arguments in favor of the Nikon 1 J4:

  • Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
  • Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
  • Faster burst: Shoots at higher frequency (60 vs 6 flaps/sec) to capture the decisive moment.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • More compact: Is smaller (100x60mm vs 136x107mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 533g or 70 percent) and hence easier to carry around.
  • More legacy lens friendly: Can take a broad range of non-native lenses via adapters.
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • More affordable: Was introduced into a lower priced category (54 percent cheaper at launch).
  • More modern: Is somewhat more recent (announced 1 year and 1 month after the D7100).


Reasons to prefer the Nikon D7100:

  • More detail: Has more megapixels (24 vs 18.2MP), which boosts linear resolution by 15%.
  • Better image quality: Scores substantially higher (30 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (3.4 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (3 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (1.6 stops ISO advantage).
  • Better sound: Can connect to an external microphone for higher quality sound recording.
  • Better sound control: Has a headphone port that enables audio monitoring while recording.
  • Easier framing: Has an optical viewfinder for image composition and settings control.
  • Easier setting verification: Features a control panel on top to check shooting parameters.
  • 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 (1229k vs 1037k dots).
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • Longer lasting: Gets more shots (950 versus 300) out of a single battery charge.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • More heavily discounted: Has been on the market for longer (launched in February 2013).

If the count of relative strengths (bullet points above) is taken as a measure, the D7100 is the clear winner of the contest (18 : 10 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.

J4 10:18 D7100

How about other alternatives? Do the specifications of the Nikon 1 J4 and the Nikon D7100 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best DSLR Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it says little about, for example, the shooting experience and imaging performance of the J4 and the D7100 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 hands-on reviews by experts are important. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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.

Care should be taken when interpreting the review scores above, though. The assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
