Olympus E-620 vs Sony A3000

The Olympus E-620 and the Sony Alpha A3000 are two digital cameras that were revealed to the public, respectively, in February 2009 and August 2013. The E-620 is a DSLR, while the A3000 is a mirrorless interchangeable lens camera. The cameras are based on a Four Thirds (E-620) and an APS-C (A3000) sensor. The Olympus has a resolution of 12.2 megapixels, whereas the Sony provides 19.8 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 Sony Alpha A3000? 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 side-by-side display below illustrates the physical size and weight of the Olympus E-620 and the Sony A3000. 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.

Compare E-620 versus A3000 top
Comparison E-620 or A3000 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A3000 is somewhat smaller (5 percent) than the Olympus E-620. Moreover, the A3000 is markedly lighter (21 percent) than the E-620. In this context, it is worth noting that neither the E-620 nor the A3000 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. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can compare the optics available for the two cameras in the Four Thirds Lens Catalog (E-620) and the Sony E-Mount Lens Catalog (A3000). Mirrorless cameras, such as the A3000, 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 A3000 can take 470 images on a single charge of its NP-FW50 power pack. The power pack in the A3000 can be charged via the USB port, which can be very convenient when travelling.

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

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 A3000 was launched at a markedly lower price (by 53 percent) than the E-620, which puts it into a different market segment. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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 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.

Of the two cameras under consideration, the Olympus E-620 features a Four Thirds sensor and the Sony A3000 an APS-C sensor. The sensor area in the A3000 is 59 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.5. The sensor in the E-620 has a native 4:3 aspect ratio, while the one in the A3000 offers a 3:2 aspect.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.

Olympus E-620 and Sony A3000 sensor measures

With 19.8MP, the A3000 offers a higher resolution than the E-620 (12.2MP), but the A3000 has marginally smaller individual pixels (pixel pitch of 4.25μm versus 4.29μm for the E-620). Yet, the A3000 is a much more recent model (by 4 years and 6 months) than the E-620, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.

The resolution advantage of the Sony A3000 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A3000 for good quality output (200 dots per inch) amounts to 27.3 x 18.2 inch or 69.3 x 46.1 cm, for very good quality (250 dpi) 21.8 x 14.5 inch or 55.4 x 36.9 cm, and for excellent quality (300 dpi) 18.2 x 12.1 inch or 46.2 x 30.8 cm. The corresponding values for the Olympus E-620 are 20.2 x 15.1 inch or 51.2 x 38.4 cm for good quality, 16.1 x 12.1 inch or 41 x 30.7 cm for very good quality, and 13.4 x 10.1 inch or 34.1 x 25.6 cm for excellent quality prints.

The Olympus E-620 has a native sensitivity range from ISO 100 to ISO 3200. The corresponding ISO settings for the Sony Alpha A3000 are ISO 100 to ISO 16000 (no boost).

E-620 versus A3000 MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 A3000 offers substantially better image quality than the E-620 (overall score 23 points higher). The advantage is based on 2.4 bits higher color depth, 2.5 EV in additional dynamic range, and 1 stops in additional low light sensitivity. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the A3000 has an electronic viewfinder (202k 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 A3000 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. On the other hand, the viewfinder of the E-620 has a higher magnification (0.48x vs 0.47x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Olympus E-620 and Sony A3000 along with similar information for a selection of comparators.

One feature that differentiates the E-620 and the A3000 is in-body image stabilization (IBIS). The E-620 reduces the risk of handshake-induced blur with all attached lenses, while the A3000 has to rely on optical image stabilization in OIS-equipped lenses to achieve the same effect.

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 A3000 does not have a selfie-screen.

The E-620 writes its imaging data to Compact Flash or xD Picture cards, while the A3000 uses SDXC or Memory Stick PRO Duo cards. The E-620 features dual card slots, which can be very useful in case a memory card fails. In contrast, the A3000 only has one slot.

Both the E-620 and the A3000 have been discontinued, but can regularly be found used on eBay. The E-620 was replaced by the Olympus E-600, while the A3000 does not have a direct successor. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Olympus and Sony websites.



Review summary

So what conclusions can be drawn? Is the Olympus E-620 better than the Sony A3000 or vice versa? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Arguments in favor of the Olympus E-620:

  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.48x vs 0.47x).
  • 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 2.5 flaps/sec) to capture the decisive moment.
  • Sharper images: Has hand-shake reducing image stabilization built-in.
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • More heavily discounted: Has been available for much longer (launched in February 2009).

ilogo

Advantages of the Sony Alpha A3000:

  • More detail: Has more megapixels (19.8 vs 12.2MP), which boosts linear resolution by 30%.
  • Better image quality: Scores substantially higher (23 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (2.4 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (2.5 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (1 stops ISO advantage).
  • Broader imaging potential: Can capture not only stills but also 1080/60i video.
  • More framing info: Has an electronic viewfinder that displays shooting data.
  • More complete view: Has a viewfinder with a larger field of view (100% vs 95%).
  • Larger screen: Has a bigger rear LCD (3.0" vs 2.7") for image review and settings control.
  • Less heavy: Has a lower weight (by 110g or 21 percent) and is thus easier to take along.
  • Easier travel charging: Can be conveniently charged via its USB port.
  • 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 modern: Reflects 4 years and 6 months of technical progress since the E-620 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the A3000 is the clear winner of the contest (13 : 8 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.

E-620 08:13 A3000

How about other alternatives? Do the specifications of the Olympus E-620 and the Sony A3000 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-620 or the A3000. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.

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 (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.

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
