Olympus E-400 vs Panasonic GX8

The Olympus E-400 and the Panasonic Lumix DMC-GX8 are two digital cameras that were officially introduced, respectively, in September 2006 and July 2015. The E-400 is a DSLR, while the GX8 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 20.2 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-400 and the Panasonic Lumix DMC-GX8? 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 side-by-side display below illustrates the physical size and weight of the Olympus E-400 and the Panasonic GX8. 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 measures are rounded to the nearest millimeter.

The GX8 can be obtained in two different colors (black, silver), while the E-400 is only available in black.

Compare E-400 versus GX8 top
Comparison E-400 or GX8 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic GX8 is notably smaller (12 percent) than the Olympus E-400. However, the GX8 is markedly heavier (12 percent) than the E-400. It is noteworthy in this context that the GX8 is splash and dust-proof, while the E-400 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-400) and the Micro Four Thirds Lens Catalog (GX8). Mirrorless cameras, such as the GX8, 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-400 gets 500 shots out of its BLS-1 battery, while the GX8 can take 330 images on a single charge of its DMW-BLC12 power pack.

Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.

The price is, of course, an important factor in any camera decision. 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 E-400 was launched at a markedly lower price (by 42 percent) than the GX8, 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 size of the imaging sensor is a crucial determinant 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.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.

Olympus E-400 and Panasonic GX8 sensor measures

While the two cameras under review share the same sensor size, the GX8 offers a higher resolution of 20.2 megapixels, compared with 10 MP of the E-400. This megapixels advantage translates into a 42 percent gain in linear resolution. On the other hand, these sensor specs imply that the GX8 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.34μm versus 4.74μm for the E-400). However, it should be noted that the GX8 is much more recent (by 8 years and 10 months) than the E-400, 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 GX8 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GX8 for good quality output (200 dots per inch) amounts to 25.9 x 19.4 inch or 65.8 x 49.4 cm, for very good quality (250 dpi) 20.7 x 15.6 inch or 52.7 x 39.5 cm, and for excellent quality (300 dpi) 17.3 x 13 inch or 43.9 x 32.9 cm. The corresponding values for the Olympus E-400 are 18.2 x 13.7 inch or 46.3 x 34.7 cm for good quality, 14.6 x 10.9 inch or 37.1 x 27.8 cm for very good quality, and 12.2 x 9.1 inch or 30.9 x 23.2 cm for excellent quality prints.

The Olympus E-400 has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Panasonic Lumix DMC-GX8 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.

E-400 versus GX8 MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports").

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The GX8 indeed provides for movie recording, while the E-400 does not. The highest resolution format that the GX8 can use is 4K/30p.

 

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the GX8 has an electronic viewfinder (2360k dots), while the E-400 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 GX8 offers a wider field of view (100%) than the one in the E-400 (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the GX8 has a higher magnification (0.77x vs 0.46x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The following table reports on some other key feature differences and similarities of the Olympus E-400, the Panasonic GX8, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The E-400 has one, while the GX8 does not. While the built-in flash of the E-400 is not very powerful, it can at times be useful as a fill-in light.

The GX8 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-400 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 GX8 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 GX8 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-400 writes its imaging data to Compact Flash or xD Picture cards, while the GX8 uses SDXC cards. The E-400 features dual card slots, which can be very useful in case a memory card fails. In contrast, the GX8 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-400 and Panasonic Lumix DMC-GX8 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the GX8 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the E-400 does not offer wifi capability.

Both the E-400 and the GX8 have been discontinued, but can regularly be found used on eBay. The E-400 was replaced by the Olympus E-410, while the GX8 was followed by the Panasonic GX9. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Olympus and Panasonic websites.

If the count of individual advantages (bullet points above) is taken as a guide, the GX8 is the clear winner of the contest (21 : 7 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision on a new camera. 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.

E-400 07:21 GX8

How about other alternatives? Do the specifications of the Olympus E-400 and the Panasonic GX8 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 technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the E-400 or the GX8 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 why hands-on reviews by experts are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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 above review scores should be interpreted 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.
