Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus PEN E-PM1 and the Panasonic Lumix DMC-G10? 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-PM1 vs Panasonic G10
The physical size and weight of the Olympus E-PM1 and the Panasonic G10 are illustrated 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 size dimensions are rounded to the nearest millimeter.
The E-PM1 can be obtained in six different colors (black, silver, brown, pink, purple, white), while the G10 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 G10 is considerably larger (48 percent) than the Olympus E-PM1. Moreover, the G10 is substantially heavier (46 percent) than the E-PM1. In this context, it is worth noting that neither the E-PM1 nor the G10 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.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

Any camera decision will obviously take relative prices into account. 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 two cameras under review were launched at the same price and fall into the same 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
Sensor comparison: Olympus E-PM1 vs Panasonic G10
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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better isolate a subject from the background. On the downside, larger sensors are more costly to manufacture and tend to 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.
While the two cameras under review share the same sensor size, the E-PM1 offers a slightly higher resolution of 12.2 megapixels, compared with 12 MP of the G10. This megapixels advantage translates into a 0.8 percent gain in linear resolution. On the other hand, these sensor specs imply that the E-PM1 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 4.29μm versus 4.33μm for the G10). In this context, it should be noted, however, that the E-PM1 is a somewhat more recent model (by 1 year and 3 months) than the G10, and its sensor might have benefitted from technological advances during this time that at least partly compensate for the smaller pixel size.
The Olympus PEN E-PM1 has a native sensitivity range from ISO 100 to ISO 12800. The corresponding ISO settings for the Panasonic Lumix DMC-G10 are ISO 100 to ISO 6400 (no boost).
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"). The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras are not only capable of taking still images, but can also record movies. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the E-PM1 provides a higher video resolution than the G10. It can shoot video footage at 1080/60i, while the Panasonic is limited to 720/30p.
Feature comparison: Olympus E-PM1 vs Panasonic G10
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the G10 has an electronic viewfinder (202k dots), which can be very helpful when shooting in bright sunlight. In contrast, the E-PM1 relies on live view and the rear LCD for framing. That said, the E-PM1 can be equipped with an optional viewfinder – the VF-2. The table below summarizes some of the other core capabilities of the Olympus E-PM1 and Panasonic G10 in connection with corresponding information for a sample of similar cameras.

One feature that differentiates the E-PM1 and the G10 is in-body image stabilization (IBIS). The E-PM1 reduces the risk of handshake-induced blur with all attached lenses, while the G10 has to rely on optical image stabilization in OIS-equipped lenses to achieve the same effect.
Concerning the storage of imaging data, both the E-PM1 and the G10 write their files to SDXC cards.
Connectivity comparison: Olympus E-PM1 vs Panasonic G10
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-PM1 and Panasonic Lumix DMC-G10 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the E-PM1 and the G10 have been discontinued, but can regularly be found used on eBay. The G10 was replaced by the Panasonic G3, while the E-PM1 was followed by the Olympus E-PM2. 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-PM1 vs Panasonic G10
So what is the bottom line? Is there a clear favorite between the Olympus E-PM1 and the Panasonic G10? Which camera is better? The listing below highlights the relative strengths of the two models.
Advantages of the Olympus PEN E-PM1:
- Better video: Provides higher definition movie capture (1080/60i vs 720/30p).
- Faster burst: Shoots at higher frequency (5.5 vs 2.6 flaps/sec) to capture the decisive moment.
- More compact: Is smaller (110x64mm vs 124x84mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 123g or 32 percent) and hence easier to carry around.
- Sharper images: Has hand-shake reducing image stabilization built-in.
- More modern: Is somewhat more recent (announced 1 year and 3 months after the G10).
Reasons to prefer the Panasonic Lumix DMC-G10:
- Easier framing: Has an electronic viewfinder for image framing and settings control.
- Longer lasting: Gets more shots (380 versus 330) out of a single battery charge.
- Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
- More heavily discounted: Has been on the market for longer (launched in March 2010).
If the count of individual advantages (bullet points above) is taken as a guide, the E-PM1 emerges as the winner of the contest (6 : 4 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-PM1 and the Panasonic G10 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 the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the E-PM1 or the G10 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-PM1 vs Panasonic G10
This is why hands-on reviews by experts 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.

Care should be taken when interpreting the review scores above, 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 comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
