Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus Evolt E-330 and the Sony Alpha A6000? 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-330 and the Sony A6000 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth dimensions are rounded to the nearest millimeter.

The A6000 can be obtained in three different colors (black, silver, white), while the E-330 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 Sony A6000 is considerably smaller (34 percent) than the Olympus E-330. Moreover, the A6000 is substantially lighter (46 percent) than the E-330. In this context, it is worth noting that neither the E-330 nor the A6000 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-330) and the Sony E-Mount Lens Catalog (A6000). Mirrorless cameras, such as the A6000, 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-330 gets 750 shots out of its Olympus BLM-1 battery, while the A6000 can take 360 images on a single charge of its Sony NP-FW50 power pack. The power pack in the A6000 can be charged via the USB port, which can be very convenient when travelling.

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 A6000 was launched at a markedly lower price (by 40 percent) than the E-330, 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 size of the sensor inside a digital camera is one of the key determinants of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixels in a sensor of the same technological generation. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to 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.

Of the two cameras under consideration, the Olympus E-330 features a Four Thirds sensor and the Sony A6000 an APS-C sensor. The sensor area in the A6000 is 63 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-330 has a native 4:3 aspect ratio, while the one in the A6000 offers a 3:2 aspect.

With 24MP, the A6000 offers a higher resolution than the E-330 (7.4MP), but the A6000 has smaller individual pixels (pixel pitch of 3.91μm versus 5.51μm for the E-330). Yet, the A6000 is a much more recent model (by 8 years) than the E-330, 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 A6000 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A6000 for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Olympus E-330 are 15.7 x 11.8 inches or 39.8 x 29.9 cm for good quality, 12.5 x 9.4 inches or 31.9 x 23.9 cm for very good quality, and 10.5 x 7.8 inches or 26.6 x 19.9 cm for excellent quality prints.

The A6000 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Olympus Evolt E-330 has a native sensitivity range from ISO 100 to ISO 400, which can be extended to ISO 100-1600. The corresponding ISO settings for the Sony Alpha A6000 are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 100-51200.

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.

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. 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 can also record movies. The A6000 indeed provides for movie recording, while the E-330 does not. The highest resolution format that the A6000 can use is 1080/60p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the A6000 has an electronic viewfinder (1440k dots), while the E-330 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 A6000 offers a wider field of view (100%) than the one in the E-330 (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the A6000 has a higher magnification (0.70x 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-330 and Sony A6000 along with similar information for a selection of comparators.

The E-330 writes its imaging data to Compact Flash or xD Picture cards, while the A6000 uses SDXC or Memory Stick PRO Duo cards. The E-330 features dual card slots, which can be very useful in case a memory card fails. In contrast, the A6000 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 Evolt E-330 and Sony Alpha A6000 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A6000 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the E-330 does not provide wifi capability.

Both the E-330 and the A6000 have been discontinued, but can regularly be found used on ebay. The A6000 was replaced by the Sony A6300, while the E-330 does not have a direct successor. Further information on the features and operation of the E-330 and A6000 can be found, respectively, in the Olympus E-330 Manual (free pdf) or the online Sony A6000 Manual.

Review summary

So how do things add up? Is there a clear favorite between the Olympus E-330 and the Sony A6000? Which camera is better? The listing below highlights the relative strengths of the two models.

Arguments in favor of the Olympus Evolt E-330:

• Brighter framing: Features an optical viewfinder for clear, lag-free composition.
• Longer lasting: Can take more shots (750 versus 360) on a single battery charge.
• Greater peace of mind: Features a second card slot as a backup in case of memory card failure.

If the count of relative strengths (bullet points above) is taken as a measure, the A6000 is the clear winner of the contest (21 : 4 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-330 and the Sony A6000 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 incomplete and does no justice, for example, to the way the E-330 or the A6000 perform in practice. 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 where reviews by experts come in. 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.

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. Also, please note that some of the review sites have changed their methodology and reporting over time.
