Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus E-450 and the Olympus E-510? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.

Body comparison

The physical size and weight of the Olympus E-450 and the Olympus E-510 are illustrated 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.

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 notably larger (6 percent) than the Olympus E-450. Moreover, the E-510 is markedly heavier (22 percent) than the E-450. In this context, it is worth noting that neither the E-450 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 compare the optics available in the Four Thirds Lens Catalog.

Concerning battery life, the E-450 gets 500 shots out of its Olympus BLS-1 battery, while the E-510 can take 750 images on a single charge of its Olympus BLM-1 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

Any camera decision will naturally be influenced heavily by the price. 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 38 percent) than the E-510, 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

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. 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 are more costly to manufacture and tend to 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 chip-set technology, the E-450 uses a more advanced image processing engine (TruePic III+) than the E-510 (TruePic III), with benefits for noise reduction, color accuracy, and processing speed.

The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 10 megapixels. This similarity in sensor specs implies that both the E-450 and the E-510 have the same pixel density, as well as the same pixel size. It should, however, be noted that the E-450 is much more recent (by 2 years) than the E-510, and its sensor will have benefitted from technological advances during this time.

The Olympus E-450 has a native sensitivity range from ISO 100 to ISO 1600. The Olympus E-510 offers exactly the same ISO settings.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

For many cameras, data on sensor performance has been reported by DXO Mark. 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. Of the two cameras under review, the E-450 has a notably higher overall DXO score than the E-510 (overall score 4 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.3 bits higher color depth, 0.5 EV in additional dynamic range, and 0.2 stops in additional low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The E-450 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 viewfinders of both cameras offer the same field of view (95%), as well as the same magnification (0.46x). The following table reports on some other key feature differences and similarities of the Olympus E-450, the Olympus E-510, and comparable cameras.

One feature that differentiates the E-510 and the E-450 is in-body image stabilization (IBIS). The E-510 reduces the risk of handshake-induced blur with all attached lenses, while the E-450 offers no blur reduction with lenses that themselves do not provide optical image stabilization.

Concerning the storage of imaging data, both the E-450 and the E-510 write their files to Compact Flash or xD Picture cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails.

Connectivity comparison

For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Olympus E-450 and Olympus E-510 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the E-450 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-450 does not have a direct successor. Further information on the features and operation of the E-450 and E-510 can be found, respectively, in the Olympus E-450 Manual (free pdf) or the online Olympus E-510 Manual.

Review summary

So what is the bottom line? Is there a clear favorite between the Olympus E-450 and the Olympus E-510? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

Reasons to prefer the Olympus E-450:

• Better image quality: Scores markedly higher (4 points) in the DXO overall assessment.
• Better jpgs: Has a more modern image processing engine (TruePic III+ vs TruePic III).
• Larger screen: Has a bigger rear LCD (2.7" vs 2.5") for image review and settings control.
• Faster burst: Shoots at higher frequency (3.5 vs 3 flaps/sec) to capture the decisive moment.
• Less heavy: Is lighter (by 98g or 18 percent) and hence easier to carry around.
• More affordable: Was introduced into a lower priced category (38 percent cheaper at launch).
• More modern: Reflects 2 years of technical progress since the E-510 launch.

Arguments in favor of the Olympus E-510:

• Longer lasting: Gets more shots (750 versus 500) out of a single battery charge.
• Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
• More heavily discounted: Has been around for much longer (launched in March 2007).

If the count of relative strengths (bullet points above) is taken as a measure, the E-450 is the clear winner of the match-up (7 : 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 before making a camera decision. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

How about other alternatives? Do the specifications of the Olympus E-450 and the Olympus E-510 place the cameras among the top in their class? Find out in the latest Best DSLR Camera listing whether the two cameras rank among the cream of the crop.

In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the E-450 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.

Expert reviews

This is where reviews by experts come in. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.

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. 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
