Going beyond this snapshot of core features and characteristics, what are the differences between the Panasonic Lumix DMC-LX15 and the Nikon D3400? 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

An illustration of the physical size and weight of the Panasonic LX15 and the Nikon D3400 is provided 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 measures are rounded to the nearest millimeter.

The LX15 can be obtained in two different colors (black, silver), while the D3400 is also available in two color-versions, but different ones (black, red).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D3400 is considerably larger (91 percent) than the Panasonic LX15. In this context, it is worth noting that neither the LX15 nor the D3400 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the LX15 has a lens built in, whereas the D3400 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the D3400 and their specifications in the Nikon Lens Catalog.

Concerning battery life, the LX15 gets 260 shots out of its Panasonic DMW-BLH7 battery, while the D3400 can take 1200 images on a single charge of its Nikon EN-EL14a power pack. The power pack in the LX15 can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

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.

The price is, of course, an important factor in any camera decision. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. 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 sensor inside a digital camera is one of the key determinants of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have 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 associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Panasonic LX15 features an one-inch sensor and the Nikon D3400 an APS-C sensor. The sensor area in the D3400 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. The LX15 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 24MP, the D3400 offers a higher resolution than the LX15 (20MP), but the D3400 nevertheless has larger individual pixels (pixel pitch of 3.91μm versus 2.41μm for the LX15) due to its larger sensor. It is noteworthy in this context that the two cameras were released in close succession, so that their sensors are from the same technological generation. Coming back to sensor resolution, it should be mentioned that the D3400 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Nikon D3400 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D3400 for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Panasonic LX15 are 27.4 x 18.2 inches or 69.5 x 46.3 cm for good quality, 21.9 x 14.6 inches or 55.6 x 37.1 cm for very good quality, and 18.2 x 12.2 inches or 46.3 x 30.9 cm for excellent quality prints.

The Panasonic Lumix DMC-LX15 has a native sensitivity range from ISO 125 to ISO 12800, which can be extended to ISO 80-25600. The corresponding ISO settings for the Nikon D3400 are ISO 100 to ISO 25600 (no boost).

In terms of underlying technology, the LX15 is build around a BSI-CMOS sensor, while the D3400 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.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. 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 cannot only take still pictures, but also record videos. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the LX15 provides a higher video resolution than the D3400. It can shoot video footage at 4K/30p, while the Nikon is limited to 1080/60p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the D3400 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the LX15 relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Panasonic LX15, the Nikon D3400, 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 LX15 has a touchscreen, while the D3400 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 LX15 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 LX15 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.

Concerning the storage of imaging data, both the LX15 and the D3400 write their files to SDXC cards. 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 Panasonic Lumix DMC-LX15 and Nikon D3400 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the LX15 offers wifi support, while the D3400 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

The LX15 is a recent model that features in the current product line-up of Panasonic. In contrast, the D3400 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the D3400 was succeeded by the Nikon D3500. Further information on the features and operation of the LX15 and D3400 can be found, respectively, in the Panasonic LX15 Manual (free pdf) or the online Nikon D3400 Manual.

Review summary

So what conclusions can be drawn? Is there a clear favorite between the Panasonic LX15 and the Nikon D3400? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

Reasons to prefer the Panasonic Lumix DMC-LX15:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Flexible image proportions: Has a multi-aspect sensor that allows for alternative image shapes.
• Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
• More detailed LCD: Has a higher resolution rear screen (1040k vs 921k dots).
• More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
• Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Faster burst: Shoots at higher frequency (10 vs 5 flaps/sec) to capture the decisive moment.
• Less disturbing: Has an electronic shutter option for completely silent shooting.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• Ready to shoot: Comes with a built-in lens, while the D3400 requires a separate lens.
• More compact: Is smaller (106x60mm vs 124x98mm) and thus needs less room in the bag.
• Less heavy: Is lighter even though it comes with a built-in lens (unlike the D3400).
• Easier travel charging: Can be conveniently charged via its USB port.
• Sharper images: Has hand-shake reducing image stabilization built-in.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.

Arguments in favor of the Nikon D3400:

• More detail: Has more megapixels (24 vs 20MP), which boosts linear resolution by 10%.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• 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.
• Easier framing: Has an optical viewfinder for image composition and settings control.
• More flexible: Makes it possible to change lenses and thus to use specialty optics.
• Longer lasting: Gets more shots (1200 versus 260) out of a single battery charge.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• Easier wireless transfer: Supports Bluetooth for image sharing without cables.

If the count of individual advantages (bullet points above) is taken as a guide, the LX15 is the clear winner of the match-up (16 : 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 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 Panasonic LX15 and the Nikon D3400 place the cameras among the top in their class? Find out in the latest Best Travel-Zoom 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 remains incomplete and does no justice, for example, to the way the LX15 or the D3400 perform in practice. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.

Expert reviews

This is where reviews by experts come in. 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.

The review scores listed above should be treated with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
