Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus PEN E-P2 and the Olympus E-620? 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-620 are illustrated in the side-by-side display below. 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 measures are rounded to the nearest millimeter.

The E-P2 can be obtained in three different colors (black, silver, white), while the E-620 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-620 is considerably larger (44 percent) than the Olympus E-P2. Moreover, the E-620 is substantially heavier (47 percent) than the E-P2. In this context, it is worth noting that neither the E-P2 nor the E-620 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. 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 Micro Four Thirds Lens Catalog (E-P2) and the Four Thirds Lens Catalog (E-620). Mirrorless cameras, such as the Olympus E-P2, have moreover the advantage that they have a relatively short flange to focal plane distance and can thus use many lenses from other systems via adapters.

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

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-620 was launched at a somewhat lower price (by 13 percent) than the E-P2, 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. 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 tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units 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-P2 uses a more advanced image processing engine (TruePic V) than the E-620 (TruePic III+), with benefits for noise reduction, color accuracy, and processing speed.

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-P2 and the E-620 have the same pixel density, as well as the same pixel size. It should, however, be noted that the E-P2 is a somewhat more recent model (by 8 months) than the E-620, and its sensor might have benefitted from technological advances during this time.

The Olympus PEN E-P2 has a native sensitivity range from ISO 100 to ISO 6400. The corresponding ISO settings for the Olympus E-620 are ISO 100 to ISO 3200 (no boost).

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 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 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 cannot only take still pictures, but also record videos. The E-P2 indeed provides movie recording capabilities, while the E-620 does not. The highest resolution format that the E-P2 can use is 720/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the E-620 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-P2, the Olympus E-620, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The E-620 has one, while the E-P2 does not. While the built-in flash of the E-620 is not very powerful, it can at times be useful as a fill-in light.

The E-P2 writes its imaging data to SDHC cards, while the E-620 uses Compact Flash or xD Picture cards. The E-620 features dual card slots, which can be very useful in case a memory card fails. In contrast, the E-P2 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 PEN E-P2 and Olympus E-620 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the E-P2 and the E-620 have been discontinued, but can regularly be found used on ebay. The E-620 was replaced by the Olympus E-600, while the E-P2 was followed by the Olympus E-P3. Further information on the features and operation of the E-P2 and E-620 can be found, respectively, in the Olympus E-P2 Manual (free pdf) or the online Olympus E-620 Manual.

Review summary

So what is the bottom line? Is the Olympus E-P2 better than the Olympus E-620 or vice versa? The listing below highlights the relative strengths of the two models.

Arguments in favor of the Olympus PEN E-P2:

• Better jpgs: Has a more modern image processing engine (TruePic V vs TruePic III+).
• Broader imaging potential: Can record not only still images but also 720/30p movies.
• Larger screen: Has a bigger rear LCD (3.0" vs 2.7") for image review and settings control.
• More compact: Is smaller (121x70mm vs 130x94mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 166g or 32 percent) and hence easier to carry around.
• More legacy lens friendly: Can take a broad range of non-native lenses via adapters.
• More modern: Is somewhat more recent (announced 8 months after the E-620).

Reasons to prefer the Olympus E-620:

• Easier framing: Has an optical viewfinder for image composition and settings control.
• 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 burst: Shoots at higher frequency (4 vs 3 flaps/sec) to capture the decisive moment.
• Longer lasting: Gets more shots (500 versus 300) out of a single battery charge.
• Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
• Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
• More affordable: Was released into a lower priced segment (13 percent cheaper at launch).
• More heavily discounted: Has been on the market for longer (launched in February 2009).

If the count of individual advantages (bullet points above) is taken as a guide, the E-620 emerges as the winner of the match-up (9 : 7 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 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-P2 and the Olympus E-620 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best DSLR 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 says little about, for example, the shooting experience and imaging performance of the E-P2 and the E-620 in practical situations. 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 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.

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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
