Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon 1 J4 and the Panasonic Lumix DMC-LX7? 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 Nikon 1 J4 and the Panasonic LX7. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All size dimensions are rounded to the nearest millimeter.

The J4 can be obtained in four different colors (black, silver, orange, white), while the LX7 is available in two color-versions (black, white).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic LX7 is notably larger (26 percent) than the Nikon 1 J4. In this context, it is worth noting that neither the J4 nor the LX7 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the LX7 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 would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

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 LX7 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. 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. 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 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 Panasonic LX7 a 1/1.7-inch sensor. The sensor area in the LX7 is 64 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 4.65. The sensor in the J4 has a native 3:2 aspect ratio, while the one in the LX7 offers a 4:3 aspect. The LX7 has the particularity of featuring a switch that allows to toggle between multiple aspect ratios, while maintaining the same field of view and full image resolution.

With 18.2MP, the J4 offers a higher resolution than the LX7 (10MP), but the J4 nevertheless has larger individual pixels (pixel pitch of 2.52μm versus 2.05μm for the LX7) due to its larger sensor. Moreover, the J4 is a somewhat more recent model (by 1 year and 8 months) than the LX7, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the J4 has no anti-alias filter installed, so that it can capture all the detail its 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 Panasonic LX7 are 18.2 x 13.7 inches or 46.3 x 34.7 cm for good quality, 14.6 x 10.9 inches or 37.1 x 27.8 cm for very good quality, and 12.2 x 9.1 inches or 30.9 x 23.2 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 Panasonic Lumix DMC-LX7 are ISO 80 to ISO 6400, with the possibility to increase the ISO range to 80-12800.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. 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

Apart from body and sensor, cameras can and do differ across a range of features. The J4 and the LX7 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. That said, the LX7 can be equipped with an optional viewfinder – the DMW-LVF2. The adjacent table lists some of the other core features of the Nikon 1 J4 and Panasonic LX7 along with similar information for a selection of comparators.

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 LX7 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 Panasonic LX7 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 LX7 uses SDXC cards. The J4 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the LX7 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 Panasonic Lumix DMC-LX7 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 LX7 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Both the J4 and the LX7 have been discontinued, but can regularly be found used on ebay. The LX7 was replaced by the Panasonic LX10, while the J4 was followed by the Nikon 1 J5. Further information on the features and operation of the J4 and LX7 can be found, respectively, in the Nikon 1 J4 Manual (free pdf) or the online Panasonic LX7 Manual.

Review summary

So what is the bottom line? Is the Nikon 1 J4 better than the Panasonic LX7 or vice versa? A synthesis of the relative strong points of each of the models is listed below.

Advantages of the Nikon 1 J4:

• More detail: Offers more megapixels (18.2 vs 10MP) with a 38% higher linear resolution.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Better low-light sensitivity: Requires less light for good images (1.5 stops ISO advantage).
• Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
• More detailed LCD: Has a higher resolution rear screen (1037k vs 920k dots).
• Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
• Faster burst: Shoots at higher frequency (60 vs 11 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 111x68mm) and thus needs less room in the bag.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More modern: Is somewhat more recent (announced 1 year and 8 months after the LX7).

Arguments in favor of the Panasonic Lumix DMC-LX7:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• More dynamic range: Captures a broader range of light and dark details (1 EV of extra DR).
• Flexible image proportions: Has a multi-aspect sensor that allows for alternative image shapes.
• More framing options: Can be equipped with a hotshoe-mounted accessory-viewfinder.
• 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.
• Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• More affordable: Was introduced at a lower price, despite coming with a built-in lens.
• More heavily discounted: Has been on the market for longer (launched in July 2012).

If the count of individual advantages (bullet points above) is taken as a guide, the J4 emerges as the winner of the contest (13 : 10 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera. 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 Nikon 1 J4 and the Panasonic LX7 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best Travel-Zoom 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 partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the J4 or the LX7. 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 (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.

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

The above review scores should be interpreted with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
