Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus E-5 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

An illustration of the physical size and weight of the Olympus E-5 and the Olympus E-510 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 size 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 smaller (25 percent) than the Olympus E-5. Moreover, the E-510 is substantially lighter (38 percent) than the E-5. It is worth mentioning in this context that the E-5 is splash and dust resistant, while the E-510 does not feature any corresponding weather-sealing.

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.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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.

The price is, of course, an important factor in any camera decision. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The E-510 was launched at a markedly lower price (by 53 percent) than the E-5, which puts it into a different market segment. 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.

In terms of chip-set technology, the E-5 uses a more advanced image processing engine (TruePic V+) than the E-510 (TruePic III), with benefits for noise reduction, color accuracy, and processing speed.

While the two cameras under review share the same sensor size, the E-5 offers a higher resolution of 12.2 megapixels, compared with 10 MP of the E-510. This megapixels advantage translates into a 11 percent gain in linear resolution. On the other hand, these sensor specs imply that the E-5 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-5 is much more recent (by 3 years and 6 months) than the E-510, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size.

The resolution advantage of the Olympus E-5 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the E-5 for good quality output (200 dots per inch) amounts to 20.2 x 15.1 inches or 51.2 x 38.4 cm, for very good quality (250 dpi) 16.1 x 12.1 inches or 41 x 30.7 cm, and for excellent quality (300 dpi) 13.4 x 10.1 inches or 34.1 x 25.6 cm. The corresponding values for the Olympus E-510 are 18.2 x 13.7 inches or 46.3 x 34.7 cm for good quality, 14.6 x 10.9 inches or 37.1 x 27.8 cm for very good quality, and 12.2 x 9.1 inches or 30.9 x 23.2 cm for excellent quality prints.

The Olympus E-5 has a native sensitivity range from ISO 100 to ISO 6400. The corresponding ISO settings for the Olympus E-510 are ISO 100 to ISO 1600 (no boost).

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 determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). Of the two cameras under review, the E-5 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 0.4 bits higher color depth, 0.5 EV in additional dynamic range, and 0.2 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The E-5 indeed provides movie recording capabilities, while the E-510 does not. The highest resolution format that the E-5 can use is 720/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The E-5 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 viewfinder in the E-5 offers a wider field of view (100%) than the one in the E-510 (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the E-5 has a higher magnification (0.58x vs 0.46x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Olympus E-5 and Olympus E-510 in connection with corresponding information for a sample of similar cameras.

One feature that is present on the E-5, but is missing on the E-510 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.

Concerning the storage of imaging data, both the E-5 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-5 and Olympus E-510 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Olympus E-5 (unlike the E-510) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the E-5 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-5 does not have a direct successor. Further information on the features and operation of the E-5 and E-510 can be found, respectively, in the Olympus E-5 Manual (free pdf) or the online Olympus E-510 Manual.

Review summary

So how do things add up? Is the Olympus E-5 better than the Olympus E-510 or vice versa? Below is a summary of the relative strengths of each of the two contestants.

Advantages of the Olympus E-5:

• More detail: Offers more megapixels (12.2 vs 10MP) with a 11% higher linear resolution.
• Better image quality: Scores markedly higher (4 points) in the DXO overall assessment.
• Better jpgs: Has a more modern image processing engine (TruePic V+ vs TruePic III).
• Broader imaging potential: Can record not only still images but also 720/30p movies.
• More complete view: Has a viewfinder with a larger field of view (100% vs 95%).
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.58x vs 0.46x).
• Easier setting verification: Features an LCD display on top to control shooting parameters.
• Larger screen: Has a bigger rear LCD (3.0" vs 2.5") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (920k vs 215k dots).
• More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
• Faster burst: Shoots at higher frequency (5 vs 3 flaps/sec) to capture the decisive moment.
• Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
• Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
• More modern: Reflects 3 years and 6 months of technical progress since the E-510 launch.

Reasons to prefer the Olympus E-510:

• More compact: Is smaller (136x92mm vs 142x117mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 335g or 38 percent) and is thus easier to take along.
• More affordable: Was introduced into a lower priced category (53 percent cheaper at launch).
• 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-5 is the clear winner of the match-up (16 : 4 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 wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports 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-5 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 comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the E-5 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 why hands-on reviews by experts are important. 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.

Care should be taken when interpreting the review scores above, though. The ratings are only valid when referring to cameras in the same category and of the same age. 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.
