Olympus E-620 versus Olympus E-510

The Olympus E-620 and the Olympus E-510 are two digital cameras that were revealed to the public, 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 successive views from the front, the top, and the rear are shown. 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. Cameras that are intended for semi-professional or professional use are sometimes a bit bulkier in order to provide them with the necessary ruggedness. 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.

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. 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 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

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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-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

Beyond 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 table below summarizes some of the other core capabilities of the Olympus E-620 and Olympus E-510 in connection with corresponding information for a sample of similar cameras. If you need more detail on the specs, you can find comprehensive listings, for example, in the dpreview camera hub.

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 what is the bottom line? Is there a clear favorite between the Olympus E-620 and the Olympus E-620? The listing below highlights the relative strengths of the two models.


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 flexible LCD: Has a 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).

Advantages 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 February 2009).

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 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.

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the E-620 or the E-510. 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 table below summarizes the assessments of some of the best known 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 review scores listed above should be treated 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.
