Body comparison

The side-by-side display below illustrates the physical size and weight of the Olympus E-5 and the Olympus E-P2. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. 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-5 is only available in black.

Size Olympus E-5 vs Olympus E-P2
Compare E-5 versus E-P2 top
Comparison E-5 or E-P2 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-P2 is considerably smaller (49 percent) than the Olympus E-5. Moreover, the E-P2 is substantially lighter (59 percent) than the E-5. It is worth mentioning in this context that the E-5 is splash and dust resistant, while the E-P2 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-P2). Mirrorless cameras, such as the E-P2, 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-P2 can take 300 images on a single charge of its Olympus BLS-1 power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

Note: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

Any camera decision will naturally be influenced heavily by the price. 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-P2 was launched at a markedly lower price (by 53 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.

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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better isolate a subject from the 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.

In terms of chip-set technology, the E-5 uses a more advanced image processing engine (TruePic V+) than the E-P2 (TruePic V), with benefits for noise reduction, color accuracy, and processing speed.

Olympus E-5 and Olympus E-P2 sensor measures

The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 12.2 megapixels. This similarity in sensor specs implies that both the E-5 and the E-P2 have the same pixel density, as well as the same pixel size. It should, however, be noted that the E-5 is a somewhat more recent model (by 10 months) than the E-P2, and its sensor might have benefitted from technological advances during this time.

The Olympus E-5 has a native sensitivity range from ISO 100 to ISO 6400. The Olympus PEN E-P2 offers exactly the same ISO settings.

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.

E-5 versus E-P2 MP

For many cameras, data on sensor performance has been reported by DXO Mark. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety 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-P2 relies on live view and the rear LCD for framing. That said, the E-P2 can be equipped with an optional viewfinder – the VF-2. The following table reports on some other key feature differences and similarities of the Olympus E-5, the Olympus E-P2, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The E-5 has one, while the E-P2 does not. While the built-in flash of the E-5 is not very powerful, it can at times be useful as a fill-in light.

The E-5 has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the E-P2 does not have a selfie-screen.

The E-5 writes its imaging data to Compact Flash or xD Picture cards, while the E-P2 uses SDHC cards. The E-5 features dual card slots, which can be very useful in case a memory card fails. In contrast, the E-P2 only has one slot.

Review summary

So what is the bottom line? Is there a clear favorite between the Olympus E-5 and the Olympus E-P2? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.


Arguments in favor of the Olympus E-5:

  • Better jpgs: Has a more modern image processing engine (TruePic V+ vs TruePic V).
  • Easier framing: Has an optical viewfinder for image composition and settings control.
  • Easier setting verification: Features an LCD display on top to control shooting parameters.
  • More detailed LCD: Has a higher resolution rear screen (920k vs 230k dots).
  • More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
  • Faster burst: Shoots at higher frequency (5 vs 3 flaps/sec) to capture the decisive moment.
  • Longer lasting: Can take more shots (750 versus 300) on a single battery charge.
  • Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • More modern: Is somewhat more recent (announced 10 months after the E-P2).


Reasons to prefer the Olympus PEN E-P2:

  • More compact: Is smaller (121x70mm vs 142x117mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 518g or 59 percent) and is thus easier to take along.
  • More legacy lens friendly: Can use many non-native lenses via adapters.
  • More affordable: Was introduced into a lower priced category (53 percent cheaper at launch).
  • More heavily discounted: Has been on the market for longer (launched in November 2009).

If the number of relative strengths (bullet points above) is taken as a guide, the E-5 is the clear winner of the match-up (14 : 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

E-5 14:05 E-P2

How about other alternatives? Do the specifications of the Olympus E-5 and the Olympus E-P2 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-P2. 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 following table reports the overall ratings of the cameras as published by some of the major 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.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

The above review scores should be interpreted with care, 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
