Olympus E-400 vs Panasonic TS7

The Olympus E-400 and the Panasonic Lumix DC-TS7 (labelled Panasonic FT7 in some countries) are two digital cameras that were revealed to the public, respectively, in September 2006 and May 2018. The E-400 is a DSLR, while the TS7 is a fixed lens compact. The cameras are based on a Four Thirds (E-400) and a 1/2.3-inch (TS7) 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 DC-TS7? 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 TS7. 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 TS7 can be obtained in three different colors (black, blue, orange), while the E-400 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 TS7 is notably smaller (25 percent) than the Olympus E-400. It is noteworthy in this context that the TS7 is splash and dust-proof, while the E-400 does not feature any corresponding weather-sealing. More than that, the TS7 is water-proof up to 31m and can, thus, be used for underwater photography.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the TS7 has a lens built in, whereas the E-400 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the E-400 and their specifications in the Four Thirds Lens Catalog.

Concerning battery life, the E-400 gets 500 shots out of its Olympus BLS-1 battery, while the TS7 can take 300 images on a single charge of its Panasonic DMW-BCM13 power pack. The power pack in the TS7 can be charged via the USB port, which can be very convenient when travelling.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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 obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The TS7 was launched at a lower price than the E-400, despite having a lens built in. 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. 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Olympus E-400 features a Four Thirds sensor and the Panasonic TS7 a 1/2.3-inch sensor. The sensor area in the TS7 is 88 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 5.6. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

Despite having a smaller sensor, the TS7 offers a higher resolution of 20.2 megapixels, compared with 10 MP of the E-400. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 1.18μm versus 4.74μm for the E-400). However, it should be noted that the TS7 is much more recent (by 11 years and 7 months) than the E-400, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

The resolution advantage of the Panasonic TS7 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the TS7 for good quality output (200 dots per inch) amounts to 25.9 x 19.4 inches or 65.8 x 49.4 cm, for very good quality (250 dpi) 20.7 x 15.6 inches or 52.7 x 39.5 cm, and for excellent quality (300 dpi) 17.3 x 13 inches or 43.9 x 32.9 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.

The Olympus E-400 has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Panasonic Lumix DC-TS7 are ISO 80 to ISO 3200, with the possibility to increase the ISO range to 80-6400.

In terms of underlying technology, the E-400 is build around a CMOS sensor, while the TS7 uses a BSI-CMOS imager. 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"). The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Note: DXO values in italics represent estimates based on sensor size and age.

Many modern cameras are not only capable of taking still images, but can also record movies. The TS7 indeed provides for movie recording, while the E-400 does not. The highest resolution format that the TS7 can use is 4K/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the TS7 has an electronic viewfinder (1170k 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 TS7 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. On the other hand, the viewfinder of the E-400 has a higher magnification (0.46x vs 0.45x), 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-400 and Panasonic TS7 along with similar information for a selection of comparators.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

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 TS7 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 E-400 writes its imaging data to Compact Flash or xD Picture cards, while the TS7 uses SDXC cards. The E-400 features dual card slots, which can be very useful in case a memory card fails. In contrast, the TS7 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 DC-TS7 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the E-400 has a hotshoe, while the TS7 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

Both the E-400 and the TS7 have been discontinued, but can regularly be found used on ebay. The E-400 was replaced by the Olympus E-410, while the TS7 does not have a direct successor. Further information on the features and operation of the E-400 and TS7 can be found, respectively, in the Olympus E-400 Manual (free pdf) or the online Panasonic TS7 Manual.

Review summary

So what conclusions can be drawn? Is the Olympus E-400 better than the Panasonic TS7 or vice versa? Below is a summary of the relative strengths of each of the two contestants.

Arguments in favor of the Olympus E-400:

• Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.

• Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
• Brighter framing: Features an optical viewfinder for clear, lag-free composition.
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.46x vs 0.45x).
• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/1300s) to freeze action.
• More flexible: Can take a variety of interchangeable lenses, including specialty optics.
• Longer lasting: Can take more shots (500 versus 300) on a single battery charge.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• 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 September 2006).

Advantages of the Panasonic Lumix DC-TS7:

• More detail: Has more megapixels (20.2 vs 10MP), which boosts linear resolution by 42%.
• Broader imaging potential: Can capture not only stills but also 4K/30p 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%).

• More affordable: Was introduced at a lower price, despite coming with a built-in lens.
• More modern: Reflects 11 years and 7 months of technical progress since the E-400 launch.

If the number of relative strengths (bullet points above) is taken as a guide, the TS7 is the clear winner of the contest (18 : 12 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-400 and the Panasonic TS7 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Travel-Zoom 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 partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the E-400 or the TS7. 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 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 (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 above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. 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.
