Going beyond this snapshot of core features and characteristics, what are the differences between the Leica D-LUX 5 and the Olympus E-420? 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 physical size and weight of the Leica D-LUX 5 and the Olympus E-420 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-420 is considerably larger (65 percent) than the Leica D-LUX 5. In this context, it is worth noting that neither the D-LUX 5 nor the E-420 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the D-LUX 5 has a lens built in, whereas the E-420 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 E-420 and their specifications in the Four Thirds Lens Catalog.

Concerning battery life, the D-LUX 5 gets 400 shots out of its Leica BP-DC10 battery, while the E-420 can take 500 images on a single charge of its Olympus BLS-1 power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. 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 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 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. 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 D-LUX 5 features a 1/1.7-inch sensor and the Olympus E-420 a Four Thirds sensor. The sensor area in the E-420 is 389 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 4.4 and 2.0. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3. The D-LUX 5 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.

Even though the E-420 has a larger sensor, both cameras offer the same resolution of 10 megapixels. This implies that the E-420 has a lower pixel density and larger individual pixels (with a pixel pitch of 4.74μm versus 2.14μm for the D-LUX 5), which gives it a potential advantage in terms of light gathering capacity. It should, however, be noted that the D-LUX 5 is much more recent (by 2 years and 6 months) than the E-420, and its sensor will have benefitted from technological advances during this time that at least partly compensate for the smaller pixel size.

The Leica D-LUX 5 has a native sensitivity range from ISO 80 to ISO 3200, which can be extended to ISO 80-12800. The corresponding ISO settings for the Olympus E-420 are ISO 100 to ISO 1600 (no boost).

In terms of underlying technology, the D-LUX 5 is build around a CCD sensor, while the E-420 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.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. The D-LUX 5 indeed provides movie recording capabilities, while the E-420 does not. The highest resolution format that the D-LUX 5 can use is 720/60p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the E-420 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the D-LUX 5 relies on live view and the rear LCD for framing. That said, the D-LUX 5 can be equipped with an optional viewfinder – the EVF1. The table below summarizes some of the other core capabilities of the Leica D-LUX 5 and Olympus E-420 in connection with corresponding information for a sample of similar cameras.

Both the D-LUX 5 and the E-420 have been discontinued, but can regularly be found used on ebay. The D-LUX 5 was replaced by the Leica D-LUX 6, while the E-420 does not have a direct successor. Further information on the features and operation of the D-LUX 5 and E-420 can be found, respectively, in the Leica D-LUX 5 Manual (free pdf) or the online Olympus E-420 Manual.

Review summary

So how do things add up? Is the Leica D-LUX 5 better than the Olympus E-420 or vice versa? Below is a summary of the relative strengths of each of the two contestants.

Reasons to prefer the Leica D-LUX 5:

• Flexible image proportions: Has a multi-aspect sensor that allows for alternative image shapes.
• Broader imaging potential: Can record not only still images but also 720/60p movies.
• Larger screen: Has a bigger rear LCD (3.0" vs 2.7") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (460k vs 215k dots).
• Ready to shoot: Comes with a built-in lens, while the E-420 requires a separate lens.
• More compact: Is smaller (110x65mm vs 130x91mm) and thus needs less room in the bag.
• Less heavy: Is lighter even though it comes with a built-in lens (unlike the E-420).
• Sharper images: Has hand-shake reducing image stabilization built-in.
• More prestigious: Has the Leica luxury appeal, which ensures a high resale price.
• More modern: Reflects 2 years and 6 months of technical progress since the E-420 launch.

Advantages of the Olympus E-420:

• 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.
• Faster burst: Shoots at higher frequency (3.5 vs 2.5 flaps/sec) to capture the decisive moment.
• More flexible: Makes it possible to change lenses and thus to use specialty optics.
• Longer lasting: Gets more shots (500 versus 400) out of a single battery charge.
• Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
• More heavily discounted: Has been around for much longer (launched in March 2008).

If the count of individual advantages (bullet points above) is taken as a guide, the match-up finishes in a tie (10 points each). 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape 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 D-LUX 5 and the Olympus E-420 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 comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the D-LUX 5 or the E-420 perform in practice. 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 expert reviews 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.

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. 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, please note that some of the review sites have changed their methodology and reporting over time.
