Olympus E-P3 vs Panasonic G10
The Olympus PEN E-P3 and the Panasonic Lumix DMC-G10 are two digital cameras that were announced, respectively, in June 2011 and March 2010. Both the E-P3 and the G10 are mirrorless interchangeable lens cameras that are equipped with a Four Thirds sensor. The Olympus has a resolution of 12.2 megapixels, whereas the Panasonic provides 12 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 PEN E-P3 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.
The physical size and weight of the Olympus E-P3 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-P3 can be obtained in three different colors (black, silver, 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 notably larger (24 percent) than the Olympus E-P3. Moreover, the G10 is markedly heavier (5 percent) than the E-P3. In this context, it is worth noting that neither the E-P3 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 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 retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The G10 was launched at a markedly lower price (by 38 percent) than the E-P3, which puts it into a different 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.
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 tend to be more expensive and 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.
In terms of underlying technology, both cameras are build around CMOS sensors.
While the two cameras under review share the same sensor size, the E-P3 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-P3 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-P3 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-P3 has a native sensitivity range from ISO 200 to ISO 12800. The corresponding ISO settings for the Panasonic Lumix DMC-G10 are ISO 100 to ISO 6400 (no boost).
Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the E-P3 provides a higher video resolution than the G10. It can shoot video footage at 1080/60i, while the Panasonic is limited to 720/30p.
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-P3 relies on live view and the rear LCD for framing. That said, the E-P3 can be equipped with an optional viewfinder – the VF-3. The table below summarizes some of the other core capabilities of the Olympus E-P3 and Panasonic G10 in connection with corresponding information for a sample of similar cameras.

One feature that differentiates the E-P3 and the G10 is in-body image stabilization (IBIS). The E-P3 reduces the risk of handshake-induced blur with all attached lenses, while the G10 offers no blur reduction with lenses that themselves do not provide optical image stabilization.
Concerning the storage of imaging data, both the E-P3 and the G10 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 G10 cannot take advantage of Ultra High Speed SD cards.
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-P3 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-P3 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-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.
So what is the bottom line? Which of the two cameras – the Olympus E-P3 or the Panasonic G10 – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.
Advantages of the Olympus PEN E-P3:
- Better low-light sensitivity: Requires less light for good images (0.4 stops ISO advantage).
- Better video: Provides higher definition movie capture (1080/60i vs 720/30p).
- 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 burst: Shoots at higher frequency (3 vs 2.6 flaps/sec) to capture the decisive moment.
- More compact: Is smaller (122x69mm vs 124x84mm) and thus needs less room in the bag.
- Sharper images: Has hand-shake reducing image stabilization built-in.
- Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
- 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 composition and settings control.
- Longer lasting: Gets more shots (380 versus 330) out of a single battery charge.
- More affordable: Was introduced into a lower priced category (38 percent cheaper at launch).
- 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-P3 is the clear winner of the match-up (9 : 4 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

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-P3 or the G10. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.
This is why expert reviews are important. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], 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 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.
