Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus E-520 and the Panasonic Lumix DMC- L10? 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 Olympus E-520 and the Panasonic L10 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth measures 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 Panasonic L10 is somewhat larger (4 percent) than the Olympus E-520. Moreover, the L10 is slightly heavier (4 percent) than the E-520. In this context, it is worth noting that neither the E-520 nor the L10 are weather-sealed.

The above size and weight comparisons are to some extent incomplete since they do not consider the interchangeable lenses that both of these cameras require. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can compare the optics available in the Four Thirds Lens Catalog.

The price is, of course, an important factor in any camera decision. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The L10 was launched at a somewhat lower price (by 14 percent) than the E-520, which makes it more attractive for photographers on a tight budget. 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 imaging sensor is a crucial determinant 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 more expensive and lead to bigger and heavier cameras and lenses.

Both cameras under consideration feature a Four Thirds sensor and have a format factor (sometimes also referred to as "crop factor") of 2.0. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 10 megapixels. This similarity in sensor specs implies that both the E-520 and the L10 have the same pixel density, as well as the same pixel size. It should, however, be noted that the E-520 is a somewhat more recent model (by 8 months) than the L10, and its sensor might have benefitted from technological advances during this time.

The Olympus E-520 has a native sensitivity range from ISO 100 to ISO 1600. The Panasonic Lumix DMC- L10 offers exactly the same ISO settings.

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.

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 Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The E-520 and the L10 are similar in the sense that both have an optical viewfinder. The latter is useful for getting a clear image for framing even in brightly lit environments. The viewfinders of both cameras offer the same field of view (95%), as well as the same magnification (0.46x). The following table reports on some other key feature differences and similarities of the Olympus E-520, the Panasonic L10, and comparable cameras.

One feature that differentiates the E-520 and the L10 is in-body image stabilization (IBIS). The E-520 reduces the risk of handshake-induced blur with all attached lenses, while the L10 offers no blur reduction with lenses that themselves do not provide optical image stabilization.

The E-520 writes its imaging data to Compact Flash or xD Picture cards, while the L10 uses SDHC cards. The E-520 features dual card slots, which can be very useful in case a memory card fails. In contrast, the L10 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 Olympus E-520 and Panasonic Lumix DMC- L10 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the E-520 and the L10 have been discontinued, but can regularly be found used on ebay. Neither of the two has a direct successor, so they represent the end of the respective camera lines from Olympus and Panasonic. Further information on the features and operation of the E-520 and L10 can be found, respectively, in the Olympus E-520 Manual (free pdf) or the online Panasonic L10 Manual.

Review summary

So what is the bottom line? Is the Olympus E-520 better than the Panasonic L10 or vice versa? A synthesis of the relative strong points of each of the models is listed below.

Arguments in favor of the Olympus E-520:

• Better low-light sensitivity: Requires less light for good images (0.4 stops ISO advantage).
• Larger screen: Has a bigger rear LCD (2.7" vs 2.5") for image review and settings control.
• Faster burst: Shoots at higher frequency (3.5 vs 3 flaps/sec) to capture the decisive moment.
• Longer lasting: Can take more shots (750 versus 450) on a single battery charge.
• Sharper images: Has hand-shake reducing image stabilization built-in.
• Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
• More modern: Is somewhat more recent (announced 8 months after the L10).

Reasons to prefer the Panasonic Lumix DMC- L10:

• 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.
• More affordable: Was released into a lower priced segment (14 percent cheaper at launch).
• More heavily discounted: Has been on the market for longer (launched in August 2007).

If the count of individual advantages (bullet points above) is taken as a guide, the E-520 emerges as the winner of the contest (7 : 4 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 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 Olympus E-520 and the Panasonic L10 place the cameras among the top in their class? Find out in the latest Best DSLR Camera listing whether the two cameras rank among the cream of the crop.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the E-520 and the L10 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 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.

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. 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.
