Going beyond this snapshot of core features and characteristics, what are the differences between the Leica Digilux 3 and the Nikon Coolpix L840? 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 Leica Digilux 3 and the Nikon L840. 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 L840 can be obtained in two different colors (black, red), while the Digilux 3 is only available in silver.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon L840 is considerably smaller (31 percent) than the Leica Digilux 3. In this context, it is worth noting that neither the Digilux 3 nor the L840 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the L840 has a lens built in, whereas the Digilux 3 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 Digilux 3 and their specifications in the Four Thirds Lens Catalog.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, you can move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

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 L840 was launched at a lower price than the Digilux 3, despite having a lens built in. 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. 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. 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 tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Leica Digilux 3 features a Four Thirds sensor and the Nikon L840 a 1/2.3-inch sensor. The sensor area in the L840 is 88 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 5.6. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

Despite having a smaller sensor, the L840 offers a higher resolution of 15.9 megapixels, compared with 7.4 MP of the Digilux 3. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 1.33μm versus 5.51μm for the Digilux 3). However, it should be noted that the L840 is much more recent (by 8 years and 4 months) than the Digilux 3, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. Coming back to sensor resolution, it should be mentioned that the L840 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Nikon L840 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the L840 for good quality output (200 dots per inch) amounts to 23 x 17.3 inches or 58.5 x 43.9 cm, for very good quality (250 dpi) 18.4 x 13.8 inches or 46.8 x 35.1 cm, and for excellent quality (300 dpi) 15.4 x 11.5 inches or 39 x 29.3 cm. The corresponding values for the Leica Digilux 3 are 15.7 x 11.8 inches or 39.8 x 29.9 cm for good quality, 12.5 x 9.4 inches or 31.9 x 23.9 cm for very good quality, and 10.5 x 7.8 inches or 26.6 x 19.9 cm for excellent quality prints.

The Leica Digilux 3 has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Nikon Coolpix L840 are ISO 100 to ISO 6400 (no boost).

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.

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"). 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 are not only capable of taking still images, but also of capturing video footage. The L840 indeed provides for movie recording, while the Digilux 3 does not. The highest resolution format that the L840 can use is 1080/60i.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the Digilux 3 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the L840 relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Leica Digilux 3 and Nikon L840 in connection with corresponding information for a sample of similar cameras.

It is notable that the Digilux 3 has a hotshoe, while the L840 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

Both the Digilux 3 and the L840 have been discontinued, but can regularly be found used on ebay. The L840 was replaced by the Nikon B500, while the Digilux 3 does not have a direct successor. Further information on the features and operation of the Digilux 3 and L840 can be found, respectively, in the Leica Digilux 3 Manual (free pdf) or the online Nikon L840 Manual.

Review summary

So what is the bottom line? Is there a clear favorite between the Leica Digilux 3 and the Nikon L840? Which camera is better? The listing below highlights the relative strengths of the two models.

Reasons to prefer the Leica Digilux 3:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• 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: Can take a variety of interchangeable lenses, including specialty optics.
• Longer lasting: Can take more shots (750 versus 590) on a single battery charge.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• More prestigious: Has the Leica luxury appeal, which ensures a high resale price.
• More heavily discounted: Has been available for much longer (launched in September 2006).

Advantages of the Nikon Coolpix L840:

• More detail: Has more megapixels (15.9 vs 7.4MP), which boosts linear resolution by 47%.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Broader imaging potential: Can capture not only stills but also 1080/60i 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 (921k vs 207k dots).
• More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
• Faster burst: Shoots at higher frequency (7.4 vs 3 flaps/sec) to capture the decisive moment.
• Ready to shoot: Comes with an integrated lens, while the Digilux 3 requires a separate lens.
• More compact: Is smaller (113x78mm vs 146x87mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight even though it has a lens built in (unlike the Digilux 3).
• Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• More affordable: Was introduced at a lower price, despite coming with a built-in lens.
• More modern: Reflects 8 years and 4 months of technical progress since the Digilux 3 launch.

If the number of relative strengths (bullet points above) is taken as a guide, the L840 is the clear winner of the contest (15 : 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 Leica Digilux 3 and the Nikon L840 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Superzoom 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 says little about, for example, the shooting experience and imaging performance of the Digilux 3 and the L840 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 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.

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. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
