Panasonic L10 versus Olympus E-420

The Panasonic Lumix DMC- L10 and the Olympus E-420 are two digital cameras that were announced, respectively, in August 2007 and March 2008. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with a Four Thirds sensor. Both cameras offer a resolution of 10 megapixel. 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: Panasonic L10 vs Olympus E-420

An illustration of the physical size and weight of the Panasonic L10 and the Olympus E-420 is provided in the side-by-side display below. Three consecutive perspectives from the front, the top, and the back are presented. All width, height and depth measures 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 L10 – 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 Olympus E-420 is notably smaller (9 percent) than the Panasonic L10. Moreover, the E-420 is markedly lighter (21 percent) than the L10. In this context, it is worth noting that neither the L10 nor the E-420 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. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The two cameras under review were launched at the same price and fall into the same market segment. 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: Panasonic L10 vs Olympus E-420

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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to isolate a subject from the 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.

Panasonic L10 and Olympus E-420 sensor measures

The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 10 megapixel. This similarity in sensor specs implies that both the L10 and the E-420 have the same pixel density, as well as the same pixel size. It should, however, be noted that the E-420 is a somewhat more recent model (by 6 months) than the L10, and its sensor might have benefitted from technological advances during this time.

L10 versus E-420 MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Both the L10 and the E-420 offer Live View, so that they make it possible to use the rear screen for framing. Both cameras are still-image focused and cannot record videos.

Feature comparison: Panasonic L10 vs Olympus E-420

Apart from body and sensor, cameras can and do differ across a range of features. The L10 and the E-420 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 following table reports on some other key feature differences and similarities of the Panasonic L10, the Olympus E-420, and comparable cameras. If you need more detail on the specs, you can find comprehensive listings, for example, in the dpreview camera hub.

Both the L10 and the E-420 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 Panasonic and Olympus.

Review summary: Panasonic L10 vs Olympus E-420

So how do things add up? Which of the two cameras – the Panasonic L10 or the Olympus E-420 – has the upper hand? Below is a summary of the relative strengths of each of the two contestants.


Arguments in favor of the Panasonic Lumix DMC- L10:

  • More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
  • More heavily discounted: Has been on the market for longer (launched in August 2007).

Reasons to prefer the Olympus E-420:

  • 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.
  • Less heavy: Has a lower weight (by 116g or 21 percent) and is thus easier to take along.
  • Longer lasting: Gets more shots (500 versus 450) out of a single battery charge.
  • More modern: Was introduced somewhat (6 months) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the E-420 emerges as the winner of the match-up (5 : 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.

L10 02:05 E-420

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the L10 or the E-420 handle or 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. This is why expert reviews are important. The following table reports the overall rankings of the cameras as published by some of the major 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. A score, therefore, has to be seen in close connection to the price and market introduction time 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
