Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus PEN E-PL2 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.

Body comparison

An illustration of the physical size and weight of the Olympus E-PL2 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 width, height and depth measures are rounded to the nearest millimeter.

The E-PL2 can be obtained in four different colors (black, silver, red, 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 notably smaller (12 percent) than the Olympus E-PL2. Moreover, the GF5 is markedly lighter (26 percent) than the E-PL2. In this context, it is worth noting that neither the E-PL2 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.

Concerning battery life, the E-PL2 gets 280 shots out of its Olympus BLS-5 battery, while the GF5 can take 360 images on a single charge of its Panasonic DMW-BLE9 power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

The price is, of course, an important factor in any camera decision. 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 GF5 was launched at a somewhat lower price (by 17 percent) than the E-PL2, 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.

Sensor comparison

The size of the imaging sensor is a crucial determinant 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 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.

While the two cameras under review share the same sensor size, the E-PL2 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-PL2 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 1 year and 2 months) than the E-PL2, 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-PL2 has a native sensitivity range from ISO 200 to ISO 6400. 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.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

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 review, the E-PL2 has a notably higher overall DXO score than the GF5 (overall score 5 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.9 bits higher color depth, 0.2 EV in additional dynamic range, The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-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 GF5 provides a better video resolution than the E-PL2. It can shoot movie footage at 1080/60i, while the Olympus is limited to 720/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The E-PL2 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-PL2 can be equipped with an optional viewfinder – the VF-2. The table below summarizes some of the other core capabilities of the Olympus E-PL2 and Panasonic GF5 in connection with corresponding information for a sample of similar cameras.

One feature that differentiates the E-PL2 and the GF5 is in-body image stabilization (IBIS). The E-PL2 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.

The E-PL2 writes its imaging data to SDHC cards, while the GF5 uses SDXC cards. The GF5 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the E-PL2 cannot take advantage of Ultra High Speed SD cards.

Connectivity comparison

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-PL2 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-PL2 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-PL2 and the GF5 have been discontinued, but can regularly be found used on ebay. The E-PL2 was replaced by the Olympus E-PL3, while the GF5 was followed by the Panasonic GF6. Further information on the features and operation of the E-PL2 and GF5 can be found, respectively, in the Olympus E-PL2 Manual (free pdf) or the online Panasonic GF5 Manual.

Review summary

So how do things add up? Is there a clear favorite between the Olympus E-PL2 and the Panasonic GF5? Which camera is better? The listing below highlights the relative strengths of the two models.

Reasons to prefer the Olympus PEN E-PL2:

• Better image quality: Scores markedly higher (5 points) in the DXO overall assessment.
• More framing options: Can be equipped with a hotshoe-mounted accessory-viewfinder.
• 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 January 2011).

Advantages of the Panasonic Lumix DMC-GF5:

• Better video: Provides higher definition movie capture (1080/60i vs 720/30p).
• 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.
• Faster burst: Shoots at higher frequency (4 vs 3 flaps/sec) to capture the decisive moment.
• More compact: Is smaller (108x67mm vs 114x72mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 95g or 26 percent) and is thus easier to take along.
• Longer lasting: Gets more shots (360 versus 280) out of a single battery charge.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More affordable: Was released into a lower priced segment (17 percent cheaper at launch).
• More modern: Was introduced somewhat (1 year and 2 months) more recently.

If the number of relative strengths (bullet points above) is taken as a guide, the GF5 is the clear winner of the contest (10 : 5 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 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-PL2 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 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-PL2 or the GF5. 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

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], digitalcameraworld [DCW], 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 review scores listed above should be treated 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 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.
