Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus PEN E-P2 and the Olympus PEN E-PL7? 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

The physical size and weight of the Olympus E-P2 and the Olympus E-PL7 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth dimensions are rounded to the nearest millimeter.

The E-P2 can be obtained in three different colors (black, silver, white), while the E-PL7 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 Olympus E-PL7 is notably smaller (9 percent) than the Olympus E-P2. However, the E-PL7 is slightly heavier (1 percent) than the E-P2. In this context, it is worth noting that neither the E-P2 nor the E-PL7 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-P2 gets 300 shots out of its Olympus BLS-1 battery, while the E-PL7 can take 350 images on a single charge of its Olympus BLS-50 power pack.

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.

The price is, of course, an important factor in any camera decision. 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 E-PL7 was launched at a somewhat lower price (by 25 percent) than the E-P2, which makes it more attractive for photographers on a tight budget. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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

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.

Technology-wise, the E-PL7 uses a more advanced image processing engine (TruePic VII) than the E-P2 (TruePic V), with benefits for noise reduction, color accuracy, and processing speed.

While the two cameras under review share the same sensor size, the E-PL7 offers a higher resolution of 15.9 megapixels, compared with 12.2 MP of the E-P2. This megapixels advantage translates into a 14 percent gain in linear resolution. On the other hand, these sensor specs imply that the E-PL7 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.76μm versus 4.29μm for the E-P2). However, it should be noted that the E-PL7 is much more recent (by 4 years and 9 months) than the E-P2, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size.

The resolution advantage of the Olympus E-PL7 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the E-PL7 for good quality output (200 dots per inch) amounts to 23 x 17.3 inches or 58.5 x 43.9 cm, for very good quality (250 dpi) 18.4 x 13.8 inches or 46.8 x 35.1 cm, and for excellent quality (300 dpi) 15.4 x 11.5 inches or 39 x 29.3 cm. The corresponding values for the Olympus E-P2 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-P2 has a native sensitivity range from ISO 100 to ISO 6400. The corresponding ISO settings for the Olympus PEN E-PL7 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.

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.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 E-PL7 offers substantially better image quality than the E-P2 (overall score 16 points higher). The advantage is based on 1.2 bits higher color depth, 2 EV in additional dynamic range, and 0.8 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 also of capturing video footage. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the E-PL7 provides a better video resolution than the E-P2. It can shoot movie footage at 1080/30p, while the E-P2 is limited to 720/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The E-P2 and the E-PL7 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. However, optional viewfinders – the VF-2 for the E-P2 and the VF-4 for the E-PL7 – are available as accessories. The following table reports on some other key feature differences and similarities of the Olympus E-P2, the Olympus E-PL7, and comparable cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The E-PL7 has a touchscreen, while the E-P2 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The Olympus E-PL7 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-P2 writes its imaging data to SDHC cards, while the E-PL7 uses SDXC cards. The E-PL7 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the E-P2 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-P2 and Olympus PEN E-PL7 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the E-PL7 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the E-P2 does not provide wifi capability.

Both the E-P2 and the E-PL7 have been discontinued, but can regularly be found used on ebay. The E-P2 was replaced by the Olympus E-P3, while the E-PL7 was followed by the Olympus E-PL8. Further information on the features and operation of the E-P2 and E-PL7 can be found, respectively, in the Olympus E-P2 Manual (free pdf) or the online Olympus E-PL7 Manual.

Review summary

So how do things add up? Which of the two cameras – the Olympus E-P2 or the Olympus E-PL7 – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.

Arguments in favor of the Olympus PEN E-P2:

• More heavily discounted: Has been available for much longer (launched in November 2009).

Reasons to prefer the Olympus PEN E-PL7:

• More detail: Has more megapixels (15.9 vs 12.2MP), which boosts linear resolution by 14%.
• Better image quality: Scores substantially higher (16 points) in the DXO overall evaluation.
• Richer colors: Generates noticeably more natural colors (1.2 bits more color depth).
• More dynamic range: Captures a broader range of light and dark details (2 EV of extra DR).
• Better low-light sensitivity: Can shoot in dim conditions (0.8 stops ISO advantage).
• Better jpgs: Has a more modern image processing engine (TruePic VII vs TruePic V).
• Better video: Provides higher definition movie capture (1080/30p vs 720/30p).
• More detailed LCD: Has a higher resolution rear screen (1037k vs 230k dots).
• More flexible LCD: Has a tilting screen for odd-angle shots in 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 (8 vs 3 flaps/sec) to capture the decisive moment.
• 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 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-I standard.
• More affordable: Was released into a lower priced segment (25 percent cheaper at launch).
• More modern: Reflects 4 years and 9 months of technical progress since the E-P2 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the E-PL7 is the clear winner of the contest (18 : 1 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 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-P2 and the Olympus E-PL7 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the E-P2 or the E-PL7. 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.

Expert reviews

This is where reviews by experts come in. 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.

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, please note that some of the review sites have changed their methodology and reporting over time.
