Olympus E-P1 vs Panasonic G7
The Olympus PEN E-P1 and the Panasonic Lumix DMC-G7 are two digital cameras that were revealed to the public, respectively, in June 2009 and May 2015. Both the E-P1 and the G7 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 15.8 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-P1 and the Panasonic Lumix DMC-G7? 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.
An illustration of the physical size and weight of the Olympus E-P1 and the Panasonic G7 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter.
The E-P1 can be obtained in three different colors (black, silver, white), while the G7 is available in two color-versions (black, silver).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic G7 is notably larger (27 percent) than the Olympus E-P1. Moreover, the G7 is markedly heavier (15 percent) than the E-P1. In this context, it is worth noting that neither the E-P1 nor the G7 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 following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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 listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The G7 was launched at a somewhat lower price (by 19 percent) than the E-P1, which makes it more attractive for photographers on a tight budget. 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. 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. 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.
While the two cameras under review share the same sensor size, the G7 offers a higher resolution of 15.8 megapixels, compared with 12.2 MP of the E-P1. This megapixels advantage translates into a 14 percent gain in linear resolution. On the other hand, these sensor specs imply that the G7 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-P1). However, it should be noted that the G7 is much more recent (by 5 years and 11 months) than the E-P1, 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 G7 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G7 for good quality output (200 dots per inch) amounts to 23 x 17.2 inches or 58.3 x 43.8 cm, for very good quality (250 dpi) 18.4 x 13.8 inches or 46.7 x 35 cm, and for excellent quality (300 dpi) 15.3 x 11.5 inches or 38.9 x 29.2 cm. The corresponding values for the Olympus E-P1 are 20.2 x 15.1 inches or 51.2 x 38.4 cm for good quality, 16.1 x 12.1 inches or 41 x 30.7 cm for very good quality, and 13.4 x 10.1 inches or 34.1 x 25.6 cm for excellent quality prints.
The Olympus PEN E-P1 has a native sensitivity range from ISO 100 to ISO 6400. The corresponding ISO settings for the Panasonic Lumix DMC-G7 are ISO 160 to ISO 25600 (no boost).
For many cameras, data on sensor performance has been reported by DXO Mark. 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 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 G7 provides a better video resolution than the E-P1. It can shoot movie footage at 4K/30p, while the Olympus is limited to 720/30p.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the G7 has an electronic viewfinder (2360k dots), which can be very helpful when shooting in bright sunlight. In contrast, the E-P1 relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Olympus E-P1 and Panasonic G7 along with similar information for a selection of comparators.
One feature that differentiates the E-P1 and the G7 is in-body image stabilization (IBIS). The E-P1 reduces the risk of handshake-induced blur with all attached lenses, while the G7 offers no blur reduction with lenses that themselves do not provide optical image stabilization.The G7 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-P1 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 G7 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 G7 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.
The E-P1 writes its imaging data to SDHC cards, while the G7 uses SDXC cards. The G7 supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the E-P1 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-P1 and Panasonic Lumix DMC-G7 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

| NFC |
It is notable that the G7 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the E-P1 does not provide wifi capability.
Both the E-P1 and the G7 have been discontinued, but can regularly be found used on eBay. The E-P1 was replaced by the Olympus E-P2, while the G7 was followed by the Panasonic G85. 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? Is the Olympus E-P1 better than the Panasonic G7 or vice versa? A synthesis of the relative strong points of each of the models is listed below.
Arguments in favor of the Olympus PEN E-P1:
- More compact: Is smaller (121x70mm vs 125x86mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 55g or 13 percent) and hence easier to carry around.
- Sharper images: Has hand-shake reducing image stabilization built-in.
- More heavily discounted: Has been available for much longer (launched in June 2009).
Advantages of the Panasonic Lumix DMC-G7:
- More detail: Has more megapixels (15.8 vs 12.2MP), which boosts linear resolution by 14%.
- Better video: Provides higher definition movie capture (4K/30p vs 720/30p).
- Better sound: Can connect to an external microphone for higher quality sound recording.
- Easier framing: Has an electronic viewfinder for image composition and settings control.
- More detailed LCD: Has a higher resolution rear screen (1040k vs 230k dots).
- More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
- Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- Faster burst: Shoots at higher frequency (7 vs 3 flaps/sec) to capture the decisive moment.
- Less disturbing: Has an electronic shutter option for completely silent shooting.
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- Longer lasting: Gets more shots (350 versus 300) out of a single battery charge.
- 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-II standard.
- More affordable: Was released into a lower priced segment (19 percent cheaper at launch).
- More modern: Reflects 5 years and 11 months of technical progress since the E-P1 launch.
If the count of relative strengths (bullet points above) is taken as a measure, the G7 is the clear winner of the contest (17 : 4 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding 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.

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-P1 or the G7 perform in practice. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.
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 (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.

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.
