Olympus E-420 versus Olympus E-620

The Olympus E-420 and the Olympus E-620 are two digital cameras that were revealed to the public, respectively, in March 2008 and February 2009. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with a Four Thirds sensor. The E-420 has a resolution of 10 megapixel, whereas the E-620 provides 12.2 MP.

Body comparison

An illustration of the physical size and weight of the Olympus E-420 and the Olympus E-620 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 E-420 – 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-620 is somewhat larger (3 percent) than the Olympus E-420. Moreover, the E-620 is markedly heavier (18 percent) than the E-420. Cameras that are aimed at professionals or semi-pros tend to be a bit bulkier in order to give them the necessary environmental and shock resistance. In this context, it is worth noting that neither the E-420 nor the E-620 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-420 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

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. 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 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-420. 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-420). However, it should be noted that the E-620 is a somewhat more recent model (by 11 months) than the E-420, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of individual pixels.

Sensor resolution

Consistent information on actual sensor performance is available from DXO Mark for most cameras. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. 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-420 and the E-620 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-420 and the E-620 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-420, the Olympus E-620, and comparable cameras. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

Both the E-420 and the E-620 have been discontinued, but can regularly be found used on ebay. The E-620 was replaced by the Olympus E-600, while the E-420 does not have a direct successor.

Summary

So what is the bottom line? Is the Olympus E-420 better than the Olympus E-620 or vice versa? The listing below highlights the relative strengths of the two models.


Advantages of the Olympus E-420:

  • Less heavy: Is lighter (by 81g or 16 percent) and hence easier to carry around.
  • More affordable: Was introduced into a lower priced segment (14 percent cheaper at launch).
  • More heavily discounted: Has been on the market for longer (launched in March 2008).

Arguments in favor of the Olympus E-620:

  • More detail: Has more megapixels (12.2 vs 10MP), which boosts linear resolution by 11%.
  • More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
  • Sharper images: Has stabilization technology build-in to reduce the impact of hand-shake.
  • More modern: Was introduced somewhat (11 months) more recently.

If the count of individual advantages (bullet points above) is taken as a guide, the E-620 comes out slightly ahead of the E-420 (4 : 3 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.

E-420 03:04 E-620

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the E-420 and the E-620 in practical situations. 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 why hands-on reviews by experts are important. The adjacent table relays the overall verdicts of several of the most popular camera review sites. You can find the full text of the reviews, respectively, at 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
