Going beyond this snapshot of core features and characteristics, what are the differences between the Sony Alpha A5000 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 side-by-side display below illustrates the physical size and weight of the Sony A5000 and the Olympus E-620. 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 A5000 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 (76 percent) than the Sony A5000. Moreover, the E-620 is substantially heavier (94 percent) than the A5000. In this context, it is worth noting that neither the A5000 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. 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 Sony E-Mount Lens Catalog (A5000) and the Four Thirds Lens Catalog (E-620). Mirrorless cameras, such as the Sony A5000, 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.

Concerning battery life, the A5000 gets 420 shots out of its Sony NP-FW50 battery, while the E-620 can take 500 images on a single charge of its Olympus BLS-1 power pack. The power pack in the A5000 can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

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 A5000 was launched at a markedly lower price (by 36 percent) than the E-620, 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 imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Sony A5000 features an APS-C sensor and the Olympus E-620 a Four Thirds sensor. The sensor area in the E-620 is 37 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 2.0. The sensor in the A5000 has a native 3:2 aspect ratio, while the one in the E-620 offers a 4:3 aspect.

With 19.8MP, the A5000 offers a higher resolution than the E-620 (12.2MP), but the A5000 has marginally smaller individual pixels (pixel pitch of 4.25μm versus 4.29μm for the E-620). However, the A5000 is a much more recent model (by 4 years and 10 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 pixels.

The resolution advantage of the Sony A5000 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A5000 for good quality output (200 dots per inch) amounts to 27.3 x 18.2 inches or 69.3 x 46.1 cm, for very good quality (250 dpi) 21.8 x 14.5 inches or 55.4 x 36.9 cm, and for excellent quality (300 dpi) 18.2 x 12.1 inches or 46.2 x 30.8 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 Sony Alpha A5000 has a native sensitivity range from ISO 100 to ISO 16000. 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"). Of the two cameras under review, the A5000 provides substantially higher image quality than the E-620, with an overall score that is 24 points higher. This advantage is based on 2.5 bits higher color depth, 2.7 EV in additional dynamic range, and 1 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The A5000 indeed provides movie recording capabilities, while the E-620 does not. The highest resolution format that the A5000 can use is 1080/60i.

Feature comparison

Apart from 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 A5000 relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Sony A5000 and Olympus E-620 in connection with corresponding information for a sample of similar cameras.

One feature that differentiates the E-620 and the A5000 is in-body image stabilization (IBIS). The E-620 reduces the risk of handshake-induced blur with all attached lenses, while the A5000 offers no blur reduction with lenses that themselves do not provide optical image stabilization.

The A5000 writes its imaging data to SDXC or Memory Stick PRO Duo 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 A5000 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 Sony Alpha A5000 and Olympus E-620 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A5000 offers wifi support, while the E-620 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Both the A5000 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 A5000 was followed by the Sony A5100. Further information on the features and operation of the A5000 and E-620 can be found, respectively, in the Sony A5000 Manual (free pdf) or the online Olympus E-620 Manual.

Review summary

So what is the bottom line? Which of the two cameras – the Sony A5000 or the Olympus E-620 – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.

Advantages of the Sony Alpha A5000:

• More detail: Offers more megapixels (19.8 vs 12.2MP) with a 30% higher linear resolution.
• Better image quality: Scores substantially higher (24 points) in the DXO overall assessment.
• Richer colors: Generates images with noticeably better colors (2.5 bits more color depth).
• More dynamic range: Captures a larger spectrum of light and dark details (2.7 EV of extra DR).
• Better low-light sensitivity: Requires less light for good images (1 stops ISO advantage).
• Broader imaging potential: Can record not only still images but also 1080/60i movies.
• Larger screen: Has a bigger rear LCD (3.0" vs 2.7") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (461k vs 230k dots).
• More compact: Is smaller (110x63mm vs 130x94mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 252g or 48 percent) and hence easier to carry around.
• Easier travel charging: Can be conveniently charged via its USB port.
• More legacy lens friendly: Can take a broad range of non-native lenses via adapters.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• More affordable: Was introduced into a lower priced category (36 percent cheaper at launch).
• More modern: Reflects 4 years and 10 months of technical progress since the E-620 launch.

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.
• Faster burst: Shoots at higher frequency (4 vs 3.5 flaps/sec) to capture the decisive moment.
• Longer lasting: Gets more shots (500 versus 420) out of a single battery charge.
• Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
• More heavily discounted: Has been around for much longer (launched in February 2009).

If the number of relative strengths (bullet points above) is taken as a guide, the A5000 is the clear winner of the match-up (16 : 8 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 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 Sony A5000 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 A5000 and the E-620 in practical situations. 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 where reviews by experts come in. The adjacent summary-table relays the overall verdicts of several of the most popular 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.

The above review scores should be interpreted with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. A score, therefore, has to be seen in close connection to the price and market introduction time 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.
