Olympus E-620 versus Olympus E-520

The Olympus E-620 and the Olympus E-520 are two digital cameras that were revealed to the public, respectively, in February 2009 and May 2008. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with a Four Thirds sensor. The E-620 has a resolution of 12.2 megapixel, whereas the E-520 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 Olympus E-520

The physical size and weight of the Olympus E-620 and the Olympus E-520 are illustrated in the side-by-side display below. Three successive views from the front, the top, and the rear 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 Olympus E-520 is somewhat larger (2 percent) than the Olympus E-620. Moreover, the E-520 is slightly heavier (3 percent) than the E-620. In this context, it is worth noting that neither the E-620 nor the E-520 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.

Concerning battery life, the E-620 gets 500 shots out of its BLS-1 battery, while the E-520 can take 750 images on a single charge of its BLM-1 power pack.

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: Olympus E-620 vs Olympus E-520

The size of the sensor inside a digital camera is one of the key determinants of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have richer color depth than smaller pixels 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.

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.

Olympus E-620 and Olympus E-520 sensor measures

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 E-520. 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 E-520). In this context, it should be noted, however, that the E-620 is a somewhat more recent model (by 9 months) than the E-520, and its sensor might have benefitted from technological advances during this time that at least partly compensate for the smaller pixel size.

E-620 versus E-520 MP

For most cameras, data on sensor performance has been reported by DXO Mark. 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 Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar image quality. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Both the E-620 and the E-520 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: Olympus E-620 vs Olympus E-520

Beyond body and sensor, cameras can and do differ across a range of features. The E-620 and the E-520 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 Olympus E-520 along with similar information for a selection of comparators. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

Both the E-620 and the E-520 have been discontinued, but can regularly be found used on eBay. The E-620 was replaced by the Olympus E-600, while the E-520 does not have a direct successor.

Review summary: Olympus E-620 vs Olympus E-520

So what conclusions can be drawn? Is the Olympus E-620 better than the Olympus E-520 or vice versa? A synthesis of the relative strong points of each of the models is listed below.


Advantages of the Olympus E-620:

  • More detail: Offers more megapixels (12.2 vs 10MP) with a 11% higher linear resolution.
  • More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
  • Faster burst: Shoots at higher frequency (4 vs 3.5 flaps/sec) to capture the decisive moment.
  • More modern: Is somewhat more recent (announced 9 months after the E-520).


Arguments in favor of the Olympus E-520:

  • Longer lasting: Gets more shots (750 versus 500) out of a single battery charge.
  • More heavily discounted: Has been on the market for longer (launched in May 2008).

If the count of relative strengths (bullet points above) is taken as a measure, the E-620 emerges as the winner of the contest (4 : 2 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision on a new camera.

E-620 04:02 E-520

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 E-620 or the E-520 handle or perform in practice. 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. This is why expert reviews are important. The adjacent table relays the overall verdicts of several of the most popular 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.
