Olympus E-620 vs E-M1

The Olympus E-620 and the Olympus OM-D E-M1 are two digital cameras that were revealed to the public, respectively, in February 2009 and September 2013. The E-620 is a DSLR, while the E-M1 is a mirrorless interchangeable lens camera. Both cameras are equipped with a Four Thirds sensor. The E-620 has a resolution of 12.2 megapixels, whereas the E-M1 provides 15.9 MP.

Below is an overview of the main specs of the two cameras as a starting point for the comparison.

Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus E-620 and the Olympus OM-D E-M1? 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-620 and the Olympus E-M1 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 measures are rounded to the nearest millimeter.

The E-M1 can be obtained in two different colors (black, silver), while the E-620 is only available in black.

Comparison E-620 or E-M1 rear

In this particular case, the Olympus E-620 and the Olympus E-M1 have exactly the same width and height, and, thus, have identically-sized bodies. However, the E-M1 is markedly lighter (5 percent) than the E-620. It is noteworthy in this context that the E-M1 is splash and dust-proof, while the E-620 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-620) and the Micro Four Thirds Lens Catalog (E-M1). Mirrorless cameras, such as the E-M1, 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-620 gets 500 shots out of its BLS-1 battery, while the E-M1 can take 350 images on a single charge of its BLN-1 power pack.

Any camera decision will obviously take relative prices into account. 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 markedly lower price (by 50 percent) than the E-M1, 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 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-M1 uses a more advanced image processing engine (TruePIC VII) than the E-620 (TruePic III+), with benefits for noise reduction, color accuracy, and processing speed.

Olympus E-620 and Olympus E-M1 sensor measures

While the two cameras under review share the same sensor size, the E-M1 offers a higher resolution of 15.9 megapixels, compared with 12.2 MP of the E-620. This megapixels advantage translates into a 14 percent gain in linear resolution. On the other hand, these sensor specs imply that the E-M1 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-620). However, it should be noted that the E-M1 is much more recent (by 4 years and 6 months) than the E-620, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size. Coming back to sensor resolution, it should be mentioned that the E-M1 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Olympus E-M1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the E-M1 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-620 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 E-M1 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Olympus E-620 has a native sensitivity range from ISO 100 to ISO 3200. The corresponding ISO settings for the Olympus OM-D E-M1 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.

E-620 versus E-M1 MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. Of the two cameras under consideration, the E-M1 offers substantially better image quality than the E-620 (overall score 18 points higher). The advantage is based on 1.7 bits higher color depth, 2.4 EV in additional dynamic range, and 0.5 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.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the E-M1 has an electronic viewfinder (2360k dots), while the E-620 has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The viewfinder in the E-M1 offers a wider field of view (100%) than the one in the E-620 (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the E-M1 has a higher magnification (0.74x vs 0.48x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The following table reports on some other key feature differences and similarities of the Olympus E-620, the Olympus E-M1, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The E-620 has one, while the E-M1 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 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-M1 does not have a selfie-screen.

The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the E-M1 is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).

The Olympus E-M1 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-620 writes its imaging data to Compact Flash or xD Picture cards, while the E-M1 uses SDXC cards. The E-620 features dual card slots, which can be very useful in case a memory card fails. In contrast, the E-M1 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 OM-D E-M1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the E-M1 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the E-620 does not provide wifi capability.

Studio photographers will appreciate that the Olympus E-M1 (unlike the E-620) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the E-620 and the E-M1 have been discontinued, but can regularly be found used on eBay. The E-620 was replaced by the Olympus E-600, while the E-M1 was followed by the Olympus E-M1 II. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Olympus website.

  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
  • Faster burst: Shoots at higher frequency (10 vs 4 flaps/sec) to capture the decisive moment.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • More legacy lens friendly: Can use many non-native lenses via adapters.
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • More modern: Reflects 4 years and 6 months of technical progress since the E-620 launch.

If the number of relative strengths (bullet points above) is taken as a guide, the E-M1 is the clear winner of the contest (24 : 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-620 and the Olympus E-M1 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 remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the E-620 or the E-M1. 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 expert reviews are important. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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.

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

Care should be taken when interpreting the review scores above, 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 comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
