Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus E-620 and the Olympus PEN E-P1? 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-620 and the Olympus E-P1 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 width, height and depth measures are rounded to the nearest millimeter.

The E-P1 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-P1 is considerably smaller (31 percent) than the Olympus E-620. Moreover, the E-P1 is markedly lighter (32 percent) than the E-620. In this context, it is worth noting that neither the E-620 nor the E-P1 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 Four Thirds Lens Catalog (E-620) and the Micro Four Thirds Lens Catalog (E-P1). Mirrorless cameras, such as the E-P1, 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.

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 naturally be influenced heavily by the price. 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 E-620 was launched at a somewhat lower price (by 13 percent) than the E-P1, 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. 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 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-P1 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-620 and the E-P1 have the same pixel density, as well as the same pixel size. It should, however, be noted that the E-P1 is a somewhat more recent model (by 3 months) than the E-620, and its sensor might have benefitted from technological advances during this time.

The Olympus E-620 has a native sensitivity range from ISO 100 to ISO 3200. The corresponding ISO settings for the Olympus PEN E-P1 are ISO 100 to ISO 6400 (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 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"). The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. 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. The E-P1 indeed provides for movie recording, while the E-620 does not. The highest resolution format that the E-P1 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-P1 relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Olympus E-620 and Olympus E-P1 in connection with corresponding information for a sample of similar cameras.

One difference between the cameras concerns the presence of an on-board flash. The E-620 has one, while the E-P1 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-620 writes its imaging data to Compact Flash or xD Picture cards, while the E-P1 uses SDHC cards. The E-620 features dual card slots, which can be very useful in case a memory card fails. In contrast, the E-P1 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-620 and Olympus PEN E-P1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the E-620 and the E-P1 have been discontinued, but can regularly be found used on ebay. The E-620 was replaced by the Olympus E-600, while the E-P1 was followed by the Olympus E-P2. Further information on the features and operation of the E-620 and E-P1 can be found, respectively, in the Olympus E-620 Manual (free pdf) or the online Olympus E-P1 Manual.

Review summary

So what conclusions can be drawn? Is the Olympus E-620 better than the Olympus E-P1 or vice versa? Below is a summary of the relative strengths of each of the two contestants.

Advantages of 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: Can take more shots (500 versus 300) on a single battery charge.
• Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
• Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
• More affordable: Was introduced into a lower priced segment (13 percent cheaper at launch).
• More heavily discounted: Has been on the market for longer (launched in February 2009).

Reasons to prefer the Olympus PEN E-P1:

• Better jpgs: Has a more modern image processing engine (TruePic V vs TruePic III+).
• Broader imaging potential: Can capture not only stills but also 720/30p video.
• 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 will fit more readily into a bag.
• Less heavy: Has a lower weight (by 166g or 32 percent) and is thus easier to take along.
• More legacy lens friendly: Can use many non-native lenses via adapters.
• More modern: Was introduced somewhat (3 months) more recently.

If the count of individual advantages (bullet points above) is taken as a guide, the E-620 emerges as the winner of the contest (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 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-620 and the Olympus E-P1 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it says little about, for example, the shooting experience and imaging performance of the E-620 and the E-P1 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 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. 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, please note that some of the review sites have changed their methodology and reporting over time.
