Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus PEN E-P3 and the Panasonic Lumix DMC-FZ100? 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: Olympus E-P3 vs Panasonic FZ100

An illustration of the physical size and weight of the Olympus E-P3 and the Panasonic FZ100 is provided 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 E-P3 can be obtained in three different colors (black, silver, white), while the FZ100 is only available in black.

Compare E-P3 versus FZ100 top
Comparison E-P3 or FZ100 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic FZ100 is notably larger (21 percent) than the Olympus E-P3. In this context, it is worth noting that neither the E-P3 nor the FZ100 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the FZ100 has a lens built in, whereas the E-P3 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-P3 and their specifications in the Micro Four Thirds Lens Catalog.

Concerning battery life, the E-P3 gets 330 shots out of its BLS-5 battery, while the FZ100 can take 410 images on a single charge of its DMW-BMB9 power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

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

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 FZ100 was launched at a lower price than the E-P3, 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: Olympus E-P3 vs Panasonic FZ100

The size of the sensor inside a digital camera is one of the key determinants 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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to 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.

Of the two cameras under consideration, the Olympus E-P3 features a Four Thirds sensor and the Panasonic FZ100 a 1/2.3-inch sensor. The sensor area in the FZ100 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.

In terms of underlying technology, both cameras are build around CMOS sensors.

Olympus E-P3 and Panasonic FZ100 sensor measures

Despite having a smaller sensor, the FZ100 offers a higher resolution of 14 megapixels, compared with 12.2 MP of the E-P3. 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 1.41μm versus 4.29μm for the E-P3). Moreover, it should be noted that the E-P3 is a somewhat more recent model (by 11 months) than the FZ100, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the FZ100 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Panasonic FZ100 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the FZ100 for good quality output (200 dots per inch) amounts to 21.6 x 16.2 inch or 54.9 x 41.1 cm, for very good quality (250 dpi) 17.3 x 13 inch or 43.9 x 32.9 cm, and for excellent quality (300 dpi) 14.4 x 10.8 inch or 36.6 x 27.4 cm. The corresponding values for the Olympus E-P3 are 20.2 x 15.1 inch or 51.2 x 38.4 cm for good quality, 16.1 x 12.1 inch or 41 x 30.7 cm for very good quality, and 13.4 x 10.1 inch or 34.1 x 25.6 cm for excellent quality prints.

The Olympus PEN E-P3 has a native sensitivity range from ISO 200 to ISO 12800. The corresponding ISO settings for the Panasonic Lumix DMC-FZ100 are ISO 100 to ISO 1600, with the possibility to increase the ISO range to 100-6400.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The E-P3 has a touchscreen, while the FZ100 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The FZ100 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-P3 does not have a selfie-screen.

Concerning the storage of imaging data, both the E-P3 and the FZ100 write their files to SDXC cards. The E-P3 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the FZ100 cannot take advantage of Ultra High Speed SD cards.

 

Connectivity comparison: Olympus E-P3 vs Panasonic FZ100

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.

Both the E-P3 and the FZ100 have been discontinued, but can regularly be found used on eBay. The FZ100 was replaced by the Panasonic FZ150, while the E-P3 was followed by the Olympus E-P5. 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.


Review summary: Olympus E-P3 vs Panasonic FZ100

So how do things add up? Which of the two cameras – the Olympus E-P3 or the Panasonic FZ100 – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.

ilogo

Advantages of the Olympus PEN E-P3:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Better image quality: Features a larger and more technologically advanced imaging sensor.
  • Richer colors: The sensor size advantage translates into images with better, more accurate colors.
  • More dynamic range: Larger sensor captures a wider spectrum of light and dark details.
  • Better low-light sensitivity: Larger sensor produces good images even in poorly lit environments.
  • More detailed LCD: Has a higher resolution rear screen (614k vs 460k dots).
  • Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
  • Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
  • More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
  • More compact: Is smaller (122x69mm vs 124x82mm) and thus needs less room in the bag.
  • Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
  • More modern: Is somewhat more recent (announced 11 months after the FZ100).

ilogo

Arguments in favor of the Panasonic Lumix DMC-FZ100:

  • More detail: Has more megapixels (14 vs 12.2MP), which boosts linear resolution by 7%.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Easier framing: Has an electronic viewfinder for image framing and settings control.
  • More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Faster burst: Shoots at higher frequency (11 vs 3 flaps/sec) to capture the decisive moment.
  • Ready to shoot: Has an integrated lens, whereas the E-P3 necessitates an extra lens.
  • Longer lasting: Gets more shots (410 versus 330) out of a single battery charge.
  • More affordable: Was introduced at a lower price, despite coming with a built-in lens.
  • More heavily discounted: Has been on the market for longer (launched in July 2010).

If the count of relative strengths (bullet points above) is taken as a measure, the E-P3 emerges as the winner of the contest (12 : 10 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 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.

E-P3 12:10 FZ100

How about other alternatives? Do the specifications of the Olympus E-P3 and the Panasonic FZ100 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best Superzoom 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 remains incomplete and does no justice, for example, to the way the E-P3 or the FZ100 perform in practice. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.

Expert reviews: Olympus E-P3 vs Panasonic FZ100

This is why expert reviews are important. The adjacent summary-table relays the overall verdicts of several of the most popular camera 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.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (-) not available.

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. 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, please note that some of the review sites have changed their methodology and reporting over time.
