Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus PEN E-PM1 and the Panasonic Lumix DMC-GF5? 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-PM1 and the Panasonic GF5 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-PM1 can be obtained in six different colors (black, silver, brown, pink, purple, white), while the GF5 is available in three color-versions (black, red, white).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic GF5 is somewhat larger (3 percent) than the Olympus E-PM1. Moreover, the GF5 is slightly heavier (1 percent) than the E-PM1. In this context, it is worth noting that neither the E-PM1 nor the GF5 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. If you would like to visualize and compare a different camera combination, just use the right or left arrows in the table to switch to the respective camera. Alternatively, you can also navigate to the CAM-parator app and make your selection from the full list of cameras there.

Any camera decision will obviously take relative prices into account. 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 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.
The size of the imaging sensor is a crucial determinant 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. 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 E-PM1 offers a slightly higher resolution of 12.2 megapixels, compared with 12 MP of the GF5. 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 GF5). Moreover, it should be noted that the GF5 is a somewhat more recent model (by 9 months) than the E-PM1, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of individual pixels.
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-GF5 are ISO 160 to ISO 6400, with the possibility to increase the ISO range to 160-12800.
For many cameras, data on sensor performance has been reported by DXO Mark. 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 GF5 has a markedly higher DXO score than the E-PM1 (overall score 9 points higher), which will translate into better image quality. The advantage is based on 0.4 bits higher color depth, 1.3 EV in additional dynamic range, and 0.3 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.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, and both provide the same movie specifications (1080/60i).
Apart from body and sensor, cameras can and do differ across a range of features. The E-PM1 and the GF5 are similar in the sense that neither of the two has a viewfinder. The images are, thus, framed using live view on the rear LCD. 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 GF5 in connection with corresponding information for a sample of similar cameras.
One feature that differentiates the E-PM1 and the GF5 is in-body image stabilization (IBIS). The E-PM1 reduces the risk of handshake-induced blur with all attached lenses, while the GF5 offers no blur reduction with lenses that themselves do not provide optical image stabilization.
Concerning the storage of imaging data, both the E-PM1 and the GF5 write their files to SDXC cards. The GF5 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the E-PM1 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-PM1 and Panasonic Lumix DMC-GF5 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the E-PM1 has a hotshoe, while the GF5 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.
Both the E-PM1 and the GF5 have been discontinued, but can regularly be found used on eBay. The E-PM1 was replaced by the Olympus E-PM2, while the GF5 was followed by the Panasonic GF6. 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 there a clear favorite between the Olympus E-PM1 and the Panasonic GF5? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.
Reasons to prefer the Olympus PEN E-PM1:
- More framing options: Can be equipped with a hotshoe-mounted accessory-viewfinder.
- Faster burst: Shoots at higher frequency (5.5 vs 4 flaps/sec) to capture the decisive moment.
- Sharper images: Has hand-shake reducing image stabilization built-in.
- Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
- More heavily discounted: Has been on the market for longer (launched in June 2011).
Advantages of the Panasonic Lumix DMC-GF5:
- Better image quality: Scores markedly higher (9 points) in the DXO overall evaluation.
- More dynamic range: Captures a broader range of light and dark details (1.3 EV of extra DR).
- More detailed LCD: Has a higher resolution rear screen (920k vs 460k dots).
- Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
- Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
- Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
- More modern: Was introduced somewhat (9 months) more recently.
If the count of relative strengths (bullet points above) is taken as a measure, the GF5 emerges as the winner of the match-up (7 : 5 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.
How about other alternatives? Do the specifications of the Olympus E-PM1 and the Panasonic GF5 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 says little about, for example, the shooting experience and imaging performance of the E-PM1 and the GF5 in practical situations. 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.
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.

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
