Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus E-5 and the Olympus PEN E-P5? 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-5 and the Olympus E-P5 is provided 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 size dimensions are rounded to the nearest millimeter.

The E-P5 can be obtained in three different colors (black, silver, white), while the E-5 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 Olympus E-P5 is considerably smaller (49 percent) than the Olympus E-5. Moreover, the E-P5 is substantially lighter (52 percent) than the E-5. It is worth mentioning in this context that the E-5 is splash and dust resistant, while the E-P5 does not feature any corresponding weather-sealing.

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. Both cameras have similarly sized sensors, but DSLRs have a larger flange-to-focal plane distance than mirrorless cameras, which imposes contraints on the optical engineering process and generally leads to bigger and heavier lenses. You can compare the optics available for the two cameras in the Four Thirds Lens Catalog (E-5) and the Micro Four Thirds Lens Catalog (E-P5). Mirrorless cameras, such as the E-P5, have moreover the advantage that they can use many lenses from other systems via adapters, as they have a relatively short flange to focal plane distance.

Concerning battery life, the E-5 gets 750 shots out of its Olympus BLM-5 battery, while the E-P5 can take 330 images on a single charge of its Olympus BLN-1 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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 obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The E-P5 was launched at a markedly lower price (by 41 percent) than the E-5, 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. 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 sensor inside a digital camera is one of the key determinants 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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its background. On the downside, larger sensors are more costly to manufacture and tend to 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.

Technology-wise, the E-P5 uses a more advanced image processing engine (TruePic VI) than the E-5 (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-P5 offers a higher resolution of 15.9 megapixels, compared with 12.2 MP of the E-5. This megapixels advantage translates into a 14 percent gain in linear resolution. On the other hand, these sensor specs imply that the E-P5 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-5). However, it should be noted that the E-P5 is much more recent (by 2 years and 7 months) than the E-5, 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-P5 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the E-P5 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-5 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 E-5 has a native sensitivity range from ISO 100 to ISO 6400. The corresponding ISO settings for the Olympus PEN E-P5 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.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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-P5 offers substantially better image quality than the E-5 (overall score 16 points higher). The advantage is based on 1.2 bits higher color depth, 1.9 EV in additional dynamic range, and 0.8 stops in additional low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the E-P5 provides a better video resolution than the E-5. It can shoot movie footage at 1080/30p, while the E-5 is limited to 720/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the E-5 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the E-P5 relies on live view and the rear LCD for framing. That said, the E-P5 can be equipped with an optional viewfinder – the VF-4. The adjacent table lists some of the other core features of the Olympus E-5 and Olympus E-P5 along with similar information for a selection of comparators.

One feature that is present on the E-5, but is missing on the E-P5 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.

The Olympus E-P5 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-5 writes its imaging data to Compact Flash or xD Picture cards, while the E-P5 uses SDXC cards. The E-5 features dual card slots, which can be very useful in case a memory card fails. In contrast, the E-P5 only has one slot.

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 E-5 and Olympus PEN E-P5 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the E-P5 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the E-5 does not provide wifi capability.

Studio photographers will appreciate that the Olympus E-5 (unlike the E-P5) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the E-5 and the E-P5 have been discontinued, but can regularly be found used on ebay. The E-P5 was replaced by the Olympus E-P7, while the E-5 does not have a direct successor. Further information on the features and operation of the E-5 and E-P5 can be found, respectively, in the Olympus E-5 Manual (free pdf) or the online Olympus E-P5 Manual.

Review summary

So what conclusions can be drawn? Is there a clear favorite between the Olympus E-5 and the Olympus E-P5? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

Advantages of the Olympus E-5:

• Easier framing: Has an optical viewfinder for image composition and settings control.

If the count of individual advantages (bullet points above) is taken as a guide, the E-P5 is the clear winner of the contest (17 : 9 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 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-5 and the Olympus E-P5 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Mirrorless Interchangeable Lens Camera listings 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 remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the E-5 or the E-P5. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

This is why hands-on reviews by experts are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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 are only valid when referring to cameras in the same category and of the same age. 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.
