Olympus E-620 versus Olympus E-450

The Olympus E-620 and the Olympus E-450 are two digital cameras that were officially introduced, respectively, in February 2009 and March 2009. 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-450 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-450

An illustration of the physical size and weight of the Olympus E-620 and the Olympus E-450 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth dimensions are rounded to the nearest millimeter. You can also use the toggle button 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 side – the E-620 – represents the basis for the calculations 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-450 is somewhat smaller (3 percent) than the Olympus E-620. Moreover, the E-450 is markedly lighter (16 percent) than the E-620. In this context, it is worth noting that neither the E-620 nor the E-450 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 adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. 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 camera’s price is obviously a critical decision-making factor. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The E-450 was launched at a markedly lower price (by 29 percent) than the E-620, which puts it into a different market segment. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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-450

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. 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.

In terms of underlying technology, both cameras are build around CMOS sensors.

Olympus E-620 and Olympus E-450 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-450. 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-450). It is noteworthy in this context that the two cameras were released in close succession, so that their sensors are from the same technological generation.

E-620 versus E-450 MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 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-450 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-450

Beyond body and sensor, cameras can and do differ across a range of features. The E-620 and the E-450 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-450, 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-620 and the E-450 have been discontinued, but can regularly be found used on eBay. The E-620 was replaced by the Olympus E-600, while the E-450 does not have a direct successor.

Review summary: Olympus E-620 vs Olympus E-450

So what is the bottom line? Is there a clear favorite between the Olympus E-620 and the Olympus E-450? Below is a summary of the relative strengths of each of the two contestants.


Reasons to prefer 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.
  • Sharper images: Has hand-shake reducing image stabilization build-in.


Arguments in favor of the Olympus E-450:

  • Less heavy: Has a lower weight (by 81g or 16 percent) and is thus easier to take along.
  • More affordable: Was introduced into a lower priced category (29 percent cheaper at launch).

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 relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera.

E-620 04:02 E-450

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the E-620 and the E-450 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 where reviews by experts come in. 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 ratings are only valid when refering to cameras in the same category and of the same age. A score, therefore, has to be seen in close connection to the price and market introduction time 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.
