Body comparison

The physical size and weight of the Nikon D40X and the Panasonic LX7 are illustrated 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 D40X can be obtained in two different colors (black, silver), while the LX7 is also available in two color-versions, but different ones (black, white).

Size Nikon D40X vs Panasonic LX7
Compare D40X versus LX7 top
Comparison D40X or LX7 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic LX7 is considerably smaller (35 percent) than the Nikon D40X. In this context, it is worth noting that neither the D40X 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 D40X 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 D40X and their specifications in the Nikon Lens Catalog.

Concerning battery life, the D40X gets 520 shots out of its EN-EL9 battery, while the LX7 can take 330 images on a single charge of its DMW-BCJ13 power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

Any camera decision will naturally be influenced heavily by the price. 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. The LX7 was launched at a lower price than the D40X, 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 imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. 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 D40X features an APS-C sensor and the Panasonic LX7 a 1/1.7-inch sensor. The sensor area in the LX7 is 89 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 4.65. The sensor in the D40X 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.

Nikon D40X and Panasonic LX7 sensor measures

Even though the D40X has a larger sensor, both cameras offer the same resolution of 10 megapixels. This implies that the D40X has a lower pixel density and larger individual pixels (with a pixel pitch of 6.11μm versus 2.05μm for the LX7), which gives it a potential advantage in terms of light gathering capacity. It should, however, be noted that the LX7 is much more recent (by 5 years and 4 months) than the D40X, and its sensor will have benefitted from technological advances during this time that at least partly compensate for the smaller pixel size.

The Nikon D40X has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 100-3200. 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.

In terms of underlying technology, the D40X is build around a CCD sensor, while the LX7 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.

D40X versus LX7 MP

For many cameras, data on sensor performance has been reported by DXO Mark. 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. Of the two cameras under review, the D40X provides substantially higher image quality than the LX7, with an overall score that is 13 points higher. This advantage is based on 1.7 bits higher color depth, 0.3 EV of lower dynamic range, and 1.8 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the D40X has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the LX7 relies on live view and the rear LCD for framing. That said, the LX7 can be equipped with an optional viewfinder – the DMW-LVF2. The following table reports on some other key feature differences and similarities of the Nikon D40X, the Panasonic LX7, and comparable cameras.

Review summary

So what is the bottom line? Is there a clear favorite between the Nikon D40X and the Panasonic LX7? Which camera is better? The listing below highlights the relative strengths of the two models.

ilogo

Arguments in favor of the Nikon D40X:

  • Better image quality: Scores substantially higher (13 points) in the DXO overall assessment.
  • Richer colors: Generates images with noticeably better colors (1.7 bits more color depth).
  • Better low-light sensitivity: Requires less light for good images (1.8 stops ISO advantage).
  • Easier framing: Has an optical viewfinder for image composition and settings control.
  • More flexible: Can take a variety of interchangeable lenses, including specialty optics.
  • Longer lasting: Can take more shots (520 versus 330) on a single battery charge.
  • More heavily discounted: Has been available for much longer (launched in March 2007).

ilogo

Reasons to prefer the Panasonic Lumix DMC-LX7:

  • Flexible image proportions: Has a multi-aspect sensor that allows for alternative image shapes.
  • Broader imaging potential: Can capture not only stills but also 1080/60p video.
  • Larger screen: Has a bigger rear LCD (3.0" vs 2.5") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (920k vs 230k dots).
  • Faster burst: Shoots at higher frequency (11 vs 3 flaps/sec) to capture the decisive moment.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • Ready to shoot: Comes with an integrated lens, while the D40X requires a separate lens.
  • More compact: Is smaller (111x68mm vs 124x94mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight even though it has a lens built in (unlike the D40X).
  • Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
  • More affordable: Was introduced at a lower price, despite coming with a built-in lens.
  • More modern: Reflects 5 years and 4 months of technical progress since the D40X launch.

If the count of relative strengths (bullet points above) is taken as a measure, the LX7 is the clear winner of the contest (12 : 7 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision on a new camera. 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.

D40X 07:12 LX7

How about other alternatives? Do the specifications of the Nikon D40X and the Panasonic LX7 place the cameras among the top in their class? Find out in the latest Best DSLR 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 D40X 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 where reviews by experts come in. 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 ratings are only valid when referring to cameras in the same category and of the same age. 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.
