Olympus E-400 vs Panasonic S1

The Olympus E-400 and the Panasonic Lumix DC-S1 are two digital cameras that were revealed to the public, respectively, in September 2006 and February 2019. The E-400 is a DSLR, while the S1 is a mirrorless interchangeable lens camera. The cameras are based on a Four Thirds (E-400) and a full frame (S1) sensor. The Olympus has a resolution of 10 megapixels, whereas the Panasonic provides 24 MP.

Below is an overview of the main specs of the two cameras as a starting point for the comparison.

Body comparison

The side-by-side display below illustrates the physical size and weight of the Olympus E-400 and the Panasonic S1. 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 measures are rounded to the nearest millimeter.

Size Olympus E-400 vs Panasonic S1
Compare E-400 versus S1 top
Comparison E-400 or S1 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic S1 is notably larger (39 percent) than the Olympus E-400. Moreover, the S1 is substantially heavier (134 percent) than the E-400. It is noteworthy in this context that the S1 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. Hence, you might want to study and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.

Concerning battery life, the E-400 gets 500 shots out of its Olympus BLS-1 battery, while the S1 can take 400 images on a single charge of its Panasonic DMW-BLJ31 power pack. The power pack in the S1 can be charged via the USB port, which can be very convenient when travelling.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

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 E-400 was launched at a markedly lower price (by 72 percent) than the S1, 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 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. 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 associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Olympus E-400 features a Four Thirds sensor and the Panasonic S1 a full frame sensor. The sensor area in the S1 is 276 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.0. The sensor in the E-400 has a native 4:3 aspect ratio, while the one in the S1 offers a 3:2 aspect.

Olympus E-400 and Panasonic S1 sensor measures

With 24MP, the S1 offers a higher resolution than the E-400 (10MP), but the S1 nevertheless has larger individual pixels (pixel pitch of 5.94μm versus 4.74μm for the E-400) due to its larger sensor. Moreover, the S1 is a much more recent model (by 12 years and 4 months) than the E-400, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the S1 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Panasonic S1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the S1 for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Olympus E-400 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.

Unlike the E-400, the S1 has the capacity to capture high quality composite images (96MP) by combining multiple shots after shifting its sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).

The Olympus E-400 has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Panasonic Lumix DC-S1 are ISO 100 to ISO 51200, with the possibility to increase the ISO range to 50-204800.

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.

E-400 versus S1 MP

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").

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the S1 has an electronic viewfinder (5760k 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 S1 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 S1 has a higher magnification (0.78x 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 S1, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The E-400 has one, while the S1 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 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 S1 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 S1 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 S1 uses SDXC or XQD 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-400 and Panasonic Lumix DC-S1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the S1 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 provide wifi capability.

Studio photographers will appreciate that the Panasonic S1 (unlike the E-400) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

The S1 is a recent model that features in the current product line-up of Panasonic. In contrast, the E-400 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the E-400 was succeeded by the Olympus E-410. Further information on the features and operation of the E-400 and S1 can be found, respectively, in the Olympus E-400 Manual (free pdf) or the online Panasonic S1 Manual.

  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • Easier travel charging: Can be conveniently charged via its USB port.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
  • More legacy lens friendly: Can use many non-native lenses via adapters.
  • Faster data transfer: Supports a more advanced USB protocol (3.1 vs 2.0).
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • Easier wireless transfer: Supports Bluetooth for image sharing without cables.
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • More modern: Reflects 12 years and 4 months of technical progress since the E-400 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the S1 is the clear winner of the contest (29 : 8 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.

E-400 08:29 S1

How about other alternatives? Do the specifications of the Olympus E-400 and the Panasonic S1 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 partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the E-400 or the S1. 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 expert reviews 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.

The review scores listed above should be treated with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
