Olympus E-620 versus Olympus E-510

The Olympus E-620 and the Olympus E-510 are two digital cameras that were announced, respectively, in February 2009 and March 2007. 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-510 provides 10 MP.

Body comparison

The side-by-side display below illustrates the physical size and weight of the Olympus E-620 and the Olympus E-510. 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 E-620 – represents the basis or 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-510 is somewhat larger (2 percent) than the Olympus E-620. Moreover, the E-510 is slightly heavier (3 percent) than the E-620. In this context, it is worth noting that neither the E-620 nor the E-510 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-510 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 comparisons there.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The E-620 was launched at a somewhat lower price (by 13 percent) than the E-510, 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

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. 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.

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.

Sensor size

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-510. 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-510). In this context, it should be noted, however, that the E-620 is a somewhat more recent model (by 1 year and 11 months) than the E-510, and its sensor might have benefitted from technological advances during this time that at least partly compensate for the smaller pixel size.

Sensor resolution

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 adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Both the E-620 and the E-510 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

Apart from body and sensor, cameras can and do differ across a range of features. The E-620 and the E-510 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 Olympus E-620, the Olympus E-510, and comparable cameras. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

Both the E-620 and the E-510 have been discontinued, but can regularly be found used on ebay. The E-510 was replaced by the Olympus E-520, while the E-620 was followed by the Olympus E-600.

Summary

So how do things add up? Which of the two cameras – the Olympus E-620 or the Olympus E-510 – has the upper hand? A synthesis of the relative strong points of each of the models is listed below.


Reasons to prefer 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 flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
  • Faster burst: Shoots at higher frequency (4 vs 3 flaps/sec) to capture the decisive moment.
  • More affordable: Was introduced into a lower priced segment (13 percent cheaper at launch).
  • More modern: Is somewhat more recent (announced 1 year and 11 months after the E-510).

Arguments in favor of the Olympus E-510:

  • 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 March 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 (6 : 2 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.

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-510 handle or perform in practice. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate. This is where reviews by experts come in. The adjacent table relays the overall verdicts of several of the most popular camera review sites. The detailed reviews can be accessed, respectively, on the websites of cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

The above review scores should be interpreted with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
