Olympus E-3 vs Panasonic GX7
The Olympus E-3 and the Panasonic Lumix DMC-GX7 are two digital cameras that were revealed to the public, respectively, in October 2007 and August 2013. The E-3 is a DSLR, while the GX7 is a mirrorless interchangeable lens camera. Both cameras are equipped with a Four Thirds sensor. The Olympus has a resolution of 10 megapixels, whereas the Panasonic provides 15.8 MP.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.
Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus E-3 and the Panasonic Lumix DMC-GX7? 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-3 and the Panasonic GX7 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth dimensions are rounded to the nearest millimeter.
The GX7 can be obtained in two different colors (black, silver), while the E-3 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 GX7 is considerably smaller (47 percent) than the Olympus E-3. Moreover, the GX7 is substantially lighter (54 percent) than the E-3. It is worth mentioning in this context that the E-3 is splash and dust resistant, while the GX7 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. 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-3) and the Micro Four Thirds Lens Catalog (GX7). Mirrorless cameras, such as the GX7, 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-3 gets 750 shots out of its Olympus BLM-1 battery, while the GX7 can take 350 images on a single charge of its Panasonic DMW-BLG10 power pack.
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.

Any camera decision will naturally be influenced heavily by the price. 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 GX7 was launched at a markedly lower price (by 41 percent) than the E-3, 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.
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 generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have 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.
While the two cameras under review share the same sensor size, the GX7 offers a higher resolution of 15.8 megapixels, compared with 10 MP of the E-3. This megapixels advantage translates into a 26 percent gain in linear resolution. On the other hand, these sensor specs imply that the GX7 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.77μm versus 4.74μm for the E-3). However, it should be noted that the GX7 is much more recent (by 5 years and 9 months) than the E-3, 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 GX7 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GX7 for good quality output (200 dots per inch) amounts to 23 x 17.2 inches or 58.3 x 43.8 cm, for very good quality (250 dpi) 18.4 x 13.8 inches or 46.7 x 35 cm, and for excellent quality (300 dpi) 15.3 x 11.5 inches or 38.9 x 29.2 cm. The corresponding values for the Olympus E-3 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-3 has a native sensitivity range from ISO 100 to ISO 3200. The corresponding ISO settings for the Panasonic Lumix DMC-GX7 are ISO 125 to ISO 25600 (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.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 GX7 offers substantially better image quality than the E-3 (overall score 14 points higher). The advantage is based on 1 bits higher color depth, 1.7 EV in additional dynamic range, and 0.3 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 can also record movies. The GX7 indeed provides for movie recording, while the E-3 does not. The highest resolution format that the GX7 can use is 1080/60p.
Feature comparison
Beyond body and sensor, cameras can and do differ across a range of features. For example, the GX7 has an electronic viewfinder (2760k dots), while the E-3 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 viewfinders of both cameras offer the same field of view (100%), but the viewfinder of the GX7 has a higher magnification than the one of the E-3 (0.70x vs 0.58x), 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-3 and Panasonic GX7 along with similar information for a selection of comparators.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one. |
One feature that is present on the E-3, but is missing on the GX7 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.
The E-3 has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the GX7 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 GX7 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 GX7 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-3 writes its imaging data to Compact Flash or xD Picture cards, while the GX7 uses SDXC cards. The E-3 features dual card slots, which can be very useful in case a memory card fails. In contrast, the GX7 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-3 and Panasonic Lumix DMC-GX7 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the GX7 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the E-3 does not provide wifi capability.
Studio photographers will appreciate that the Olympus E-3 (unlike the GX7) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the E-3 and the GX7 have been discontinued, but can regularly be found used on ebay. The E-3 was replaced by the Olympus E-5, while the GX7 was followed by the Panasonic GX85. Further information on the features and operation of the E-3 and GX7 can be found, respectively, in the Olympus E-3 Manual (free pdf) or the online Panasonic GX7 Manual.
Review summary
So what is the bottom line? Which of the two cameras – the Olympus E-3 or the Panasonic GX7 – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.

If the count of individual advantages (bullet points above) is taken as a guide, the GX7 is the clear winner of the contest (19 : 9 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape 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-3 and the Panasonic GX7 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 comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the E-3 or the GX7 perform in practice. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.
Expert reviews
This is where reviews by experts come in. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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 assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
