Going beyond this snapshot of core features and characteristics, what are the differences between the Leica D-LUX 5 and the Olympus E-3? 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 Leica D-LUX 5 and the Olympus E-3 is provided 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-3 is considerably larger (130 percent) than the Leica D-LUX 5. It is noteworthy in this context that the E-3 is splash and dust-proof, while the D-LUX 5 does not feature any corresponding weather-sealing.

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-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 E-3 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-3 can take 750 images on a single charge of its Olympus BLM-1 power pack.

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 naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The D-LUX 5 was launched at a lower price than the E-3, 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.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Leica D-LUX 5 features a 1/1.7-inch sensor and the Olympus E-3 a Four Thirds sensor. The sensor area in the E-3 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-3 has a larger sensor, both cameras offer the same resolution of 10 megapixels. This implies that the E-3 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 11 months) than the E-3, 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-3 are ISO 100 to ISO 3200 (no boost).

In terms of underlying technology, the D-LUX 5 is build around a CCD sensor, while the E-3 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 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 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 are not only capable of taking still images, but also of capturing video footage. The D-LUX 5 indeed provides movie recording capabilities, while the E-3 does not. The highest resolution format that the D-LUX 5 can use is 720/60p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the E-3 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-3 in connection with corresponding information for a sample of similar cameras.

One feature that is present on the E-3, but is missing on the D-LUX 5 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.

The D-LUX 5 writes its imaging data to SDXC cards, while the E-3 uses Compact Flash or xD Picture cards. The E-3 features dual card slots, which can be very useful in case a memory card fails. In contrast, the D-LUX 5 only has one slot.

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 Leica D-LUX 5 and Olympus E-3 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Olympus E-3 (unlike the D-LUX 5) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the D-LUX 5 and the E-3 have been discontinued, but can regularly be found used on ebay. The E-3 was replaced by the Olympus E-5, while the D-LUX 5 was followed by the Leica D-LUX 6. Further information on the features and operation of the D-LUX 5 and E-3 can be found, respectively, in the Leica D-LUX 5 Manual (free pdf) or the online Olympus E-3 Manual.

Review summary

So how do things add up? Is the Leica D-LUX 5 better than the Olympus E-3 or vice versa? The listing below highlights the relative strengths of the two models.

Advantages of 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 2.5") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (460k vs 230k dots).
• Ready to shoot: Comes with a built-in lens, while the E-3 requires a separate lens.
• More compact: Is smaller (110x65mm vs 142x116mm) and thus needs less room in the bag.
• Less heavy: Is lighter even though it comes with a built-in lens (unlike the E-3).
• More prestigious: Has the Leica luxury appeal, which ensures a high resale price.
• More affordable: Was introduced at a lower price, despite coming with a built-in lens.
• More modern: Reflects 2 years and 11 months of technical progress since the E-3 launch.

Reasons to prefer the Olympus E-3:

• 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.
• Easier setting verification: Features a control panel on top to check shooting parameters.
• More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
• Faster burst: Shoots at higher frequency (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 (750 versus 400) out of a single battery charge.
• Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
• Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
• 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 October 2007).

If the count of individual advantages (bullet points above) is taken as a guide, the E-3 is the clear winner of the contest (16 : 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 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.

How about other alternatives? Do the specifications of the Leica D-LUX 5 and the Olympus E-3 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 says little about, for example, the shooting experience and imaging performance of the D-LUX 5 and the E-3 in practical situations. 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 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 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. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
