Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus PEN E-PL3 and the Panasonic Lumix DMC-GM1? 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-PL3 vs Panasonic GM1

The physical size and weight of the Olympus E-PL3 and the Panasonic GM1 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All size dimensions are rounded to the nearest millimeter.

The E-PL3 can be obtained in four different colors (black, silver, red, white), while the GM1 is available in three color-versions (black, silver, red).

Comparison E-PL3 or GM1 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic GM1 is notably smaller (23 percent) than the Olympus E-PL3. Moreover, the GM1 is substantially lighter (35 percent) than the E-PL3. In this context, it is worth noting that neither the E-PL3 nor the GM1 are weather-sealed.

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. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can compare the optics available in the Micro Four Thirds Lens Catalog. Mirrorless cameras, such as the two under consideration, have the additional advantage of having a short flange to focal plane distance, which makes it possible to mount many lenses from other systems onto the camera via adapters.

Concerning battery life, the E-PL3 gets 300 shots out of its BLS-5 battery, while the GM1 can take 230 images on a single charge of its DMW-BLH7 power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

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 listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The E-PL3 was launched at a somewhat lower price (by 20 percent) than the GM1, which makes it more attractive for photographers on a tight budget. 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: Olympus E-PL3 vs Panasonic GM1

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 associated with larger, more expensive camera bodies 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.

Olympus E-PL3 and Panasonic GM1 sensor measures

While the two cameras under review share the same sensor size, the GM1 offers a higher resolution of 15.8 megapixels, compared with 12.2 MP of the E-PL3. This megapixels advantage translates into a 14 percent gain in linear resolution. On the other hand, these sensor specs imply that the GM1 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.77μm versus 4.29μm for the E-PL3). However, it should be noted that the GM1 is much more recent (by 2 years and 3 months) than the E-PL3, 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 GM1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GM1 for good quality output (200 dots per inch) amounts to 23 x 17.2 inch or 58.3 x 43.8 cm, for very good quality (250 dpi) 18.4 x 13.8 inch or 46.7 x 35 cm, and for excellent quality (300 dpi) 15.3 x 11.5 inch or 38.9 x 29.2 cm. The corresponding values for the Olympus E-PL3 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-PL3 has a native sensitivity range from ISO 200 to ISO 12800. The corresponding ISO settings for the Panasonic Lumix DMC-GM1 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 125-25600.

E-PL3 versus GM1 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"). Of the two cameras under consideration, the GM1 offers substantially better image quality than the E-PL3 (overall score 14 points higher). The advantage is based on 1.4 bits higher color depth, 1.4 EV in additional dynamic range, and 0.4 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

One feature that differentiates the E-PL3 and the GM1 is in-body image stabilization (IBIS). The E-PL3 reduces the risk of handshake-induced blur with all attached lenses, while the GM1 has to rely on optical image stabilization in OIS-equipped lenses to achieve the same effect.

The E-PL3 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 GM1 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 GM1 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 GM1 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.

Concerning the storage of imaging data, both the E-PL3 and the GM1 write their files to SDXC cards. The GM1 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the E-PL3 cannot take advantage of Ultra High Speed SD cards.

 

Connectivity comparison: Olympus E-PL3 vs Panasonic GM1

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 PEN E-PL3 and Panasonic Lumix DMC-GM1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

  • More affordable: Was introduced into a lower priced segment (20 percent cheaper at launch).
  • More heavily discounted: Has been available for much longer (launched in June 2011).

ilogo

Advantages of the Panasonic Lumix DMC-GM1:

  • More detail: Has more megapixels (15.8 vs 12.2MP), which boosts linear resolution by 14%.
  • Better image quality: Scores substantially higher (14 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (1.4 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (1.4 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (0.4 stops ISO advantage).
  • More detailed LCD: Has a higher resolution rear screen (1036k vs 460k dots).
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • More compact: Is smaller (99x55mm vs 110x64mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 109g or 35 percent) and is thus easier to take along.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
  • More modern: Reflects 2 years and 3 months of technical progress since the E-PL3 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the GM1 is the clear winner of the contest (15 : 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 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.

How about other alternatives? Do the specifications of the Olympus E-PL3 and the Panasonic GM1 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera listing 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-PL3 or the GM1 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-PL3 vs Panasonic GM1

This is why hands-on reviews by experts are important. The following table reports the overall ratings of the cameras as published by some of the major 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.

A score, therefore, has to be seen in close connection to the price and market introduction time 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.
