Olympus E-620 versus Panasonic L10

The Olympus E-620 and the Panasonic Lumix DMC- L10 are two digital cameras that were revealed to the public, respectively, in February 2009 and August 2007. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with a Four Thirds sensor. The Olympus has a resolution of 12.2 megapixel, whereas the Panasonic provides 10 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Olympus E-620 vs Panasonic L10

The side-by-side display below illustrates the physical size and weight of the Olympus E-620 and the Panasonic L10. 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 dimensions are rounded to the nearest millimeter. You can also toggle the display to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left – the E-620 – represents 100 percent across all the size and weight measures).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic L10 is notably larger (6 percent) than the Olympus E-620. Moreover, the L10 is markedly heavier (7 percent) than the E-620. In this context, it is worth noting that neither the E-620 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 find an overview of suitable optics in the Four Thirds Lens Catalog.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

The camera’s price is obviously a critical decision-making factor. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The L10 was launched at a somewhat lower price (by 14 percent) than the E-620, which makes it more attractive for photographers on a tight budget. 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: Olympus E-620 vs Panasonic L10

The size of the imaging sensor is a crucial determinant of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixels 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 are more costly to manufacture and tend to 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.

While the two cameras under review share the same sensor size, the E-620 offers a higher resolution of 12.2 megapixel, compared with 10 MP of the L10. This megapixel advantage translates into a 11 percent gain in linear resolution. On the other hand, these sensor specs imply that the E-620 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 4.29μm versus 4.74μm for the L10). In this context, it should be noted, however, that the E-620 is a somewhat more recent model (by 1 year and 5 months) than the L10, and its sensor might have benefitted from technological advances during this time that at least partly compensate for the smaller pixel size.

For many cameras, data on sensor performance has been reported by DXO Mark. 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 image quality. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Feature comparison: Olympus E-620 vs Panasonic L10

Apart from body and sensor, cameras can and do differ across a range of features. The E-620 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 adjacent table lists some of the other core features of the Olympus E-620 and Panasonic L10 along with similar information for a selection of comparators. The full specs-sheets can be found in the camera manual or in the dpreview camera hub.

One feature that differentiates the E-620 and the L10 is in-body image stabilization (IBIS). The E-620 reduces the risk of handshake-induced blur with all attached lenses, while the L10 has to rely on optical image stabilization in OIS-equipped lenses to achieve the same effect.

The E-620 writes its imaging data to Compact Flash or xD Picture cards, while the L10 uses SDHC cards. The E-620 features dual card slots, which can be very useful in case a memory card fails. In contrast, the L10 only has one slot.

Both the E-620 and the L10 have been discontinued, but can regularly be found used on eBay. The E-620 was replaced by the Olympus E-600, while the L10 does not have a direct successor.

Review summary: Olympus E-620 vs Panasonic L10

So what conclusions can be drawn? Is the Olympus E-620 better than the Panasonic L10 or vice versa? Below is a summary of the relative strengths of each of the two contestants.

Arguments in favor of the Olympus E-620:

• More detail: Offers more megapixels (12.2 vs 10MP) with a 11% higher linear resolution.
• Larger screen: Has a bigger rear LCD (2.7" vs 2.5") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (230k vs 207k dots).
• Faster burst: Shoots at higher frequency (4 vs 3 flaps/sec) to capture the decisive moment.
• Longer lasting: Can take more shots (500 versus 450) on a single battery charge.
• Sharper images: Has hand-shake reducing image stabilization build-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 1 year and 5 months after the L10).

Advantages of the Panasonic Lumix DMC- L10:

• 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 number of relative strengths (bullet points above) is taken as a guide, the E-620 is the clear winner of the match-up (8 : 2 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.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the E-620 or the L10. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased. This is why hands-on reviews by experts are important. The table below summarizes the assessments of some of the best known camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
