Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus E-510 and the Panasonic Lumix DMC-G6? 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-510 and the Panasonic G6 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth dimensions are rounded to the nearest millimeter.
The G6 can be obtained in three different colors (black, silver, white), while the E-510 is only available in black.



If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic G6 is notably smaller (17 percent) than the Olympus E-510. Moreover, the G6 is markedly lighter (28 percent) than the E-510. In this context, it is worth noting that neither the E-510 nor the G6 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. Both cameras have similarly sized sensors, but DSLRs have a larger flange-to-focal plane distance than mirrorless cameras, which imposes contraints on the optical engineering process and generally leads to bigger and heavier lenses. You can compare the optics available for the two cameras in the Four Thirds Lens Catalog (E-510) and the Micro Four Thirds Lens Catalog (G6). Mirrorless cameras, such as the G6, have moreover the advantage that they can use many lenses from other systems via adapters, as they have a relatively short flange to focal plane distance.
Concerning battery life, the E-510 gets 750 shots out of its Olympus BLM-1 battery, while the G6 can take 340 images on a single charge of its Panasonic DMW-BLC12 power pack.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

Any camera decision will naturally be influenced heavily by the price. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The G6 was launched at a somewhat lower price (by 25 percent) than the E-510, which makes it more attractive for photographers on a tight budget. 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.
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. 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 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.

While the two cameras under review share the same sensor size, the G6 offers a higher resolution of 15.9 megapixels, compared with 10 MP of the E-510. This megapixels advantage translates into a 26 percent gain in linear resolution. On the other hand, these sensor specs imply that the G6 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.76μm versus 4.74μm for the E-510). However, it should be noted that the G6 is much more recent (by 6 years and 1 month) 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 Panasonic G6 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G6 for good quality output (200 dots per inch) amounts to 23 x 17.3 inches or 58.5 x 43.9 cm, for very good quality (250 dpi) 18.4 x 13.8 inches or 46.8 x 35.1 cm, and for excellent quality (300 dpi) 15.4 x 11.5 inches or 39 x 29.3 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-510 has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Panasonic Lumix DMC-G6 are ISO 160 to ISO 12800, with the possibility to increase the ISO range to 160-25600.
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 consideration, the G6 has a markedly higher DXO score than the E-510 (overall score 9 points higher), which will translate into better image quality. The advantage is based on 0.1 bits higher color depth, 1.5 EV in additional dynamic range, and 0.5 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.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The G6 indeed provides for movie recording, while the E-510 does not. The highest resolution format that the G6 can use is 1080/60p.
Feature comparison
Beyond body and sensor, cameras can and do differ across a range of features. For example, the G6 has an electronic viewfinder (1440k dots), while the E-510 has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The viewfinder in the G6 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 G6 has a higher magnification (0.70x vs 0.46x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Olympus E-510 and Panasonic G6 along with similar information for a selection of comparators.

One feature that differentiates the E-510 and the G6 is in-body image stabilization (IBIS). The E-510 reduces the risk of handshake-induced blur with all attached lenses, while the G6 offers no blur reduction with lenses that themselves do not provide optical image stabilization.
The G6 has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the E-510 does not have a selfie-screen.The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the G6 is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).
The Panasonic G6 has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.
The E-510 writes its imaging data to Compact Flash or xD Picture cards, while the G6 uses SDXC cards. The E-510 features dual card slots, which can be very useful in case a memory card fails. In contrast, the G6 only has one slot.
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-510 and Panasonic Lumix DMC-G6 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the G6 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the E-510 does not provide wifi capability.
Both the E-510 and the G6 have been discontinued, but can regularly be found used on ebay. The E-510 was replaced by the Olympus E-520, while the G6 was followed by the Panasonic G7. Further information on the features and operation of the E-510 and G6 can be found, respectively, in the Olympus E-510 Manual (free pdf) or the online Panasonic G6 Manual.
Review summary
So what is the bottom line? Which of the two cameras – the Olympus E-510 or the Panasonic G6 – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.

Arguments in favor of the Olympus E-510:
- Brighter framing: Features an optical viewfinder for clear, lag-free composition.
- Longer lasting: Can take more shots (750 versus 340) on a single battery charge.
- Sharper images: Has hand-shake reducing image stabilization built-in.
- Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
- More heavily discounted: Has been available for much longer (launched in March 2007).

Advantages of the Panasonic Lumix DMC-G6:
- More detail: Has more megapixels (15.9 vs 10MP), which boosts linear resolution by 26%.
- Better image quality: Scores markedly higher (9 points) in the DXO overall evaluation.
- More dynamic range: Captures a broader range of light and dark details (1.5 EV of extra DR).
- Better low-light sensitivity: Can shoot in dim conditions (0.5 stops ISO advantage).
- Broader imaging potential: Can capture not only stills but also 1080/60p video.
- More framing info: Has an electronic viewfinder that displays shooting data.
- 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 (0.70x vs 0.46x).
- 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 (1036k vs 215k dots).
- More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
- Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.

If the number of relative strengths (bullet points above) is taken as a guide, the G6 is the clear winner of the contest (23 : 5 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. 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-510 and the Panasonic G6 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Mirrorless Interchangeable Lens Camera listings 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 says little about, for example, the shooting experience and imaging performance of the E-510 and the G6 in practical situations. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.
Expert reviews
This is where reviews by experts come in. The following table reports the overall ratings of the cameras as published by some of the major 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.
